Assign Owners to Automated Workloads

One pitfall I would highlight as a cybersecurity IAM practitioner is designing identity management around employees and treating non-human identities as an afterthought. Teams focus on single sign-on, MFA, and employee onboarding, but they need to give service accounts, API keys, and automated workloads the same attention.

That gap can leave applications relying on long-lived credentials with more access than they need. Even with strong controls for employees, unmanaged machine access can remain a blind spot.

I would avoid this by including non-human identities in the IAM implementation from day one. Each identity should have a clear owner, a documented purpose, and permissions limited to its actual function. Where supported, I would use workload identity federation and short-lived tokens instead of hardcoded secrets or permanent passwords. When static credentials are unavoidable, store them securely and rotate them regularly.

I would also include these identities in ongoing access reviews, checking whether they are still needed, whether their owner is still responsible, and whether their permissions remain appropriate. An identity without an owner should trigger investigation—not immediate deletion that could interrupt a critical service.

For me, the key is to manage machine identities with the same discipline as human identities, while accounting for how applications operate. Security should reduce unmanaged access without breaking the services people depend on.

 

Embed Consent Safeguards in Design

A common pitfall is implementing identity management without aligning it to data privacy and consent requirements, such as GDPR, HIPAA, or CCPA. Avoid this by applying data minimization, encrypting identity data, and enforcing role-based access control so only necessary identifiers are stored and seen. Provide clear transparency to users about how their identity data is used and build mechanisms that let users revoke access. Make these privacy and consent controls a requirement when selecting vendors and designing workflows.

 

Prune Stale Entitlements Continuously

One common pitfall is giving users more access than they actually need and then leaving that access in place for too long.

This usually happens when provisioning is easy but removing or reviewing access does not happen consistently. Over time, people can end up with old permissions, duplicate roles, or access they no longer need.

One way to avoid that is to build the identity lifecycle into the process from the beginning. Access should be based on role and business need, reviewed regularly, and removed automatically when someone changes roles or leaves the organization.

I would also make MFA and strong default settings part of the design instead of adding them later.

For me, good identity management is not just about getting users into a system. It is about making sure they only have the access they need, for as long as they need it.

These comments reflect my personal professional views and do not represent the views of my employer.

 

Bring Service Identities Into Scope

The pitfall I see most often is building identity management around people and forgetting the machines. Teams roll out single sign-on and multi-factor authentication for employees and call the project done. Meanwhile, service accounts, API keys, cloud workloads, and now AI agents all log in too. In most large environments they outnumber human users, and many of them have broad access, passwords that never change, and no named owner.

That’s the gap attackers go after. A stolen employee password usually runs into multi-factor authentication. A leaked API key often doesn’t, and nobody notices because nobody owns it.

To avoid it, put every identity in scope from day one, human or not. Start with an inventory of every account that can authenticate. Assign each one a named owner who is accountable for it. Then replace long-lived secrets with short-lived credentials that expire on their own. On large estates, I’ve found the ownership step does the most work. Once someone’s name is attached to an account, unused access gets cleaned up fast.

If your identity program only covers people, you’ve secured the front door and left the loading dock open.

 

Model Least Privilege Upfront

The biggest pitfall I see is over-provisioning access during the initial migration. Companies move from whatever they had before, maybe spreadsheets, maybe a legacy directory, and they dump everyone into broad role groups just to keep things running. Nobody wants to be the person who locks someone out on day one.

The problem is that temporary becomes permanent. At Softline Solutions I manage a GCP platform serving 1,500+ client accounts. When we onboarded a new identity management layer, we started with tight role definitions from day one. It took longer. People complained. But six months later we had clean access logs and no role explosion. Teams that skip this step end up with 200 custom roles that nobody understands, and revoking access becomes a political problem instead of a technical one.

My advice: define your least-privilege model before migration, not after. It’s way harder to take access away than to never grant it.

Anchor Records to Immutable Subject IDs

Using a person’s name as the identity key is a common implementation mistake. Names change, collide and get entered differently across systems. If permissions and audit events point to a name, a rename can break the link between a person and their history. A second person with the same name can make an account merge especially dangerous.

We require consistent name spelling across our internal systems so accounts can be matched, and we turn on two-factor authentication for work accounts from day one. Those controls serve different purposes. Consistent spelling helps people reconcile records; two-factor authentication protects sign-in. Neither makes a name a durable technical identifier.

For a digital identity product, I’d assign an opaque, immutable subject ID when the account is created. Keep names and email addresses as editable attributes, and have authorization rules, integrations and audit records refer to the subject ID. A change of surname or email then updates the profile without transferring access or severing the audit trail. Define the lifecycle for duplicate accounts and rehires before migration, since automatic matching on a name can join the wrong records. Test a rename and a duplicate name end to end before rollout; if either changes who can access what, the identity model isn’t ready.

 

Purge Legacy Records Before Cutover

One of the most common pitfalls is migrating identities as they are, without cleaning them up first.

Most organizations have years of identity debt: accounts for people who left long ago, contractors who were never removed, duplicate accounts for the same person, and shared or service accounts that nobody owns. Old group memberships pile up as people change roles, so many users have far more access than their current job needs. When a new identity management solution is implemented on top of that, it simply automates the mess. Worse, stale and orphaned accounts are exactly what attackers look for, because nobody notices when they are used.

How to avoid it: treat the identity inventory as its own project phase before migration.

1. Discover every account across directories, cloud apps and local systems, including service accounts and API keys.

2. Match each account to a real owner. Anything without an owner is disabled first, then removed after a short waiting period.

3. Make HR the source of truth, so joiners, movers and leavers are created, changed and removed automatically instead of by ticket.

4. Review service accounts separately. They often have broad permissions and passwords that never change, so give them named owners, least-privilege access and a rotation plan.

5. Start with role-based access built from what people actually need, not from copying old group memberships.

Doing this upfront takes extra weeks, but it means the new system starts clean, access reviews become meaningful, and you are not carrying old risk into a new platform.

 

Reconcile Lifecycle States Across Applications

One pitfall is treating identity management as a successful-login project. Authentication can work perfectly while the person retains access they no longer need after a role change or departure.

I would define the joiner, mover, and leaver workflows before rolling out the solution. Each application needs an owner, an authoritative source for the user’s status, an explicit access rule, and evidence that provisioning or revocation actually completed. Test a role change and a departure across downstream applications, including systems that do not participate fully in single sign-on. A disabled central account is not, by itself, proof that every downstream account, session, or credential has been addressed.

Microsoft’s identity lifecycle guidance makes the same lifecycle distinction and emphasizes workflow history and audit logs. My practical recommendation is to make failed or incomplete steps visible to a named owner and reconcile the expected access state with the applications’ actual state. The result to verify is correct access throughout the lifecycle, not merely the ability to sign in on day one.

Begin With Broad Functional Personas

The most detrimental pitfall in the implementation of digital identity management is complexity creep, whereby organizations confuse hyper-granular access control with strong security. Identity architecture is often seen faltering when it is overloaded with complex permissions designed for individual users or extreme edge cases. When you try to set up access rights down to each file, field, or action from day one, the administrative burden increases many times. The result is significant security bottlenecks where IT and engineering teams are swamped with access requests. Unintentionally, the business units facing delays turn to manual alternatives or request drastic exceptions that undermine the security perimeter.

To escape this problem, organizations need to have a structured, layered role-based access control strategy before touching the identity software configuration. The foundation has to rest on broad functional personas that encapsulate the vast majority of standard access needs based on type of department and its responsibilities. After establishing the basic level of access, organizations should implement other types of conditional and attribute access controls only for exceptions that involve risks or dynamic environment. This approach saves the identity management architecture clean, easy to audit and maintain by the operations team.

 

Frame Login Changes as Customer Care

My greatest fear with identity management is that people treat it as an IT project instead of a customer relationship project. The login screen is the front door of your business. If you suddenly add three more steps of verification without explaining why, your customers will get the impression that you don’t trust them as much as before instead of getting the impression that you are adding more ways to protect them. At CheapForexVPS, our traders are typically signing in under time pressure. And it takes so little to cause friction in the onboarding process that it causes a spike in abandoned sign-ups and a deluge of support requests wondering if a system has gone down. In the same way that changing the locks on the front door of a property showroom and not telling the agents would be a nightmare, technically more secure but complete mayhem, adding more verification steps to the login process needs to be treated as a customer experience project. Bring sales, support and marketing into the rollout from the start and walk through the new process of signing up for services step by step as a new customer would. Pilot test with a group of dedicated customers first and then communicate the change clearly and simply to customers before it happens so that one additional step to verify their identities is experienced as further care of them instead of a further obstacle to them.

 

Establish Emergency Credentials for IdP Outages

One of the biggest, most unexpected failures that can occur with Identity Providers is to design them as a single point of failure for your overall system. Yes, it’s great that you can centralize SSO and MFA for all of your applications. But if the IdP fails for any reason (whether it’s a bug, a hardware or network failure, or simply an expired certificate), then you’re left unable to log into your servers when you most need to. I’ve spent 40 minutes locked out of a console in the middle of a market hour trading incident just because the auth chain included the service that was failing. This kind of security can actually hinder your recovery from a failure, rather than helping. To avoid this failure, you should build the break-glass accounts that you’ll use to access your systems in case of failure before you go live with your IdP. You should store their credentials securely, offline from your main IdP, with split custody, of course. Then you should alert loudly every time they’re used, and rotate them for every use. And then you need to test failure of your IdP on a regular basis, e.g., every quarter. Simulate an IdP outage, and then see how long it takes for you to get a root shell on your servers. If nobody has tried to do this, then it clearly doesn’t work.

 

Conduct Quarterly Ghost Credential Hunts

The biggest pitfall I see with identity management is that everyone designs for the front door and forgets the back one. All the energy goes into login. SSO, MFA, a slick onboarding flow where a new hire gets access to everything on day one. Then somebody leaves and it’s a checklist in a Google Doc that half gets followed.

Here’s the sneaky part. Even with SSO, disabling someone’s main account doesn’t always cut everything off. When we audited ours, we found stuff hanging around that SSO never touched. API keys created by a contractor months earlier. OAuth connections to third-party tools that kept working on their own. A shared login for an old analytics tool that three former team members still technically knew. Nothing bad had happened. But “nothing bad happened yet” isn’t a security policy.

How to avoid it: build your offboarding flow first, before onboarding. Sounds backwards, but if you can’t cleanly remove someone, you shouldn’t be granting them access in the first place. Every time you add a tool, the question isn’t just “how do people get in?” It’s “how do we get them out, and what do they leave behind?”

Then do a quarterly ghost hunt. Pull every active account, key, and token across your tools and match it against your current team list. Anything without a living, current owner gets killed. It’s boring, takes an afternoon, and it’s probably the highest-value security hour you’ll spend all quarter.

 

Test Department Workflows With Users

One of the biggest mistakes is deploying identity management without considering its impact on workflows in advance, treating it as a purely technical implementation project. Teams are focused on technical integration and compliance, and only after implementing do they realize that the user login experience disrupted workflows that were not even considered.

This is what happened with our single sign-on deployment. From a technical point of view, everything worked perfectly with all 14 internal applications, but after the launch, help desk tickets regarding access problems grew by 52% in one month, as some departments had workflows relying on specific behavior of the previous system, such as joint logins for certain shift-based positions.

To solve this problem, we deployed an additional testing phase two weeks before the implementation involving real end-users from each department, rather than only IT. When deploying the next system migration using this approach, access-related tickets became 8% of the number in the previous deployment.

Conclusion: a technically correct solution can fail if it is not validated against actual workflows in advance.

 

Move Tenant Enforcement Into Databases

The pitfall: enforcing identity in application code and assuming that’s a boundary. It isn’t. It’s a convention that holds until one developer forgets a filter, and in a system where every tenant’s data lives in the same tables, that one omission hands a user someone else’s records with no error and no log entry.

I built a breach harness for exactly this in a multi-tenant agent-memory system. It plays an agent acting for one tenant against an app layer with the scoping bug in it, and the failure it produces is silent, which is the worst way to fail. Nothing crashes. The wrong data just comes back.

The fix was to move the identity boundary into the database itself with row-level security, so the tenant’s identity travels with every query and the database refuses rows that don’t belong to it. The point isn’t that the database is smarter. It’s that app-code bugs now fail closed: a forgotten filter returns nothing instead of everything. You still write the app-layer checks, you just stop trusting them to be the last line.

The cost is real and I’d say so: row-level policies make some queries slower and harder to reason about, and debugging a query that returns nothing takes longer than debugging one that returns too much. That’s the trade. I’d take it every time, because the second failure is the one you read about.

 

Decouple Authentication From Authorization

I’m Aleks Sztemberg, co-founder of Stormly, and one pitfall is treating authentication as if it automatically answers the authorization question.

Knowing who someone is doesn’t mean every system acting on their behalf should have access to everything they can access. This becomes particularly important with AI agents. At Stormly, for example, a user can connect an AI client through MCP to investigate analytics data, but we scope that access to the specific Stormly project rather than assuming the agent should inherit broad access.

My recommendation is to design permissions around the task and resource, not just the identity. “We know who you are” and “you’re allowed to access this” should always be two separate decisions.

That principle becomes even more important as identities increasingly authorize software and AI agents to act on their behalf.

 

Set Contractor Expirations at Hire

The pitfall I see most in identity management is accounts for freelancers and contractors who’ve finished a project staying live for months. Managing a marketing team plus outside contractors myself, my advice is to tie every access grant to an end date at the point of onboarding, not offboarding, and put someone named in charge of revoking it the day the contract ends.

 

Recheck Trust as Risk Shifts

The pitfall that quietly kills digital identity rollouts is treating verification as a one-time gate instead of a continuous trust signal.

We ran into this directly with Sumsub, one of the brands using Pageloot. Their workflow needed QR codes tied to verified user journeys, and the first version we helped configure treated the scan as the endpoint. Verification happened once, at onboarding, and then the system assumed that identity stayed valid forever. Six months later they were dealing with flagged accounts that had passed initial checks but drifted outside compliance thresholds, because nothing downstream was re-evaluating trust.

The fix is building re-verification triggers into the product logic, not just the onboarding flow. Set conditions: if a user’s behavior pattern changes significantly, if a document approaches expiration, if access scope expands, re-verify. The identity isn’t static, so the system checking it shouldn’t be either.

Most implementations skip this because re-verification adds friction and friction reads as a UX failure in early demos. But a single compromised account that passed initial KYC and then went dormant in the system costs more to explain than the friction ever would have.

 

Validate Devices Alongside Credentials

Leading Netsurit across North America, South Africa, and Europe, our teams manage identity and security architectures for hundreds of organizations, from mid-market firms to enterprise deployments.

A major pitfall is treating identity management solely as user credential verification while completely ignoring device health and context-based access rules. This blind spot exposes systems to account hijacking whenever a compromised or unmanaged device connects with valid login details.

To avoid this, implement automated Conditional Access policies paired with multi-factor authentication and endpoint compliance. When we deployed the Microsoft Enterprise Mobility + Security (EMS) Suite and Microsoft Intune for a major bank supporting over 40,000 users, we ensured that only verified, compliant devices across mobile and desktop could access core data and services.

Always tie identity controls directly to device compliance and multi-layered verification rather than relying on standard logins alone. This stops unauthorized access in its tracks before an unverified endpoint ever touches your cloud resources.

 

Map Authorized Email Senders Early

The biggest pitfall teams hit when rolling out identity management is treating email domains as an afterthought, focusing only on internal user logins. When organizations don’t map out third-party sending services before locking down domain identity policies like DMARC, legitimate vendor emails break and communications stall out.

To avoid this, organizations need automated visibility into every service sending on their behalf before enforcing strict Zero Trust rules. Auditing DNS records and cloud vendors manually leaves blind spots. Setting policies to monitor-only while automating authentication for authorized senders keeps critical workflows intact while shutting down impersonation.

At Valimail, we help teams automate this discovery so domain identity enforcement doesn’t break daily operations.

 

Prove Revocation Across Existing Sessions

A common pitfall is testing that people can sign in but never testing that they can actually lose access. Successful single sign-on is not proof of successful offboarding.

Microsoft documents a concrete example: an application can issue its own session token, and Microsoft Entra ID cannot directly revoke that application-issued session. Blocking a new identity-provider login therefore should not be treated as evidence that every existing application session has ended. The application’s own controls matter.

Before rollout, I would make a test account, grant only the access needed for a representative job, then change its role and revoke its access. Check both a new login and an already-open session. Record which connected applications require a separate deprovisioning step, who owns that step, and how completion will be verified. Do not assume that removing a user from one directory instantly invalidates every downstream credential.

For an agency using several client tools, that means making the exit checklist as specific as the onboarding checklist. A list of approved apps is incomplete without the owner and removal procedure for each one. My practical test is: can we demonstrate that the former user can no longer perform the protected action, rather than merely show that somebody clicked “disable”?

Monitor Access After Personnel Changes

The pitfall I see most often is treating identity management as an onboarding project. Companies invest heavily in verifying people and granting access when they join, then pay far less attention to what happens afterward.

Access accumulates over time. An employee changes roles and keeps permissions from the old one. A contractor finishes a project and their account stays active. Someone leaves, and a shared credential they used never gets changed. Each of these gaps is small on its own. Together they create the conditions fraud depends on, because an account nobody is watching is an easy one to misuse.

To avoid this, plan for the full life of every identity before you launch. Assign permissions by role and by task, so access follows the work instead of the person’s history. Keep administrative credentials in a protected list that only a few people control. Schedule regular access reviews and treat every departure as a trigger to remove access and rotate any shared credentials.

At Blue Ocean Global Technology, we apply role-based and task-level permissions in our CRM for this reason. The technology matters, but discipline around change matters more. Most identity failures happen in the months after launch, when nobody is looking.

 

Question Whether Identification Is Necessary

I’m Maurice Sikkink, founder of Yogile, and one pitfall is requiring identity simply because your system is capable of collecting it.

A good example is photo sharing. Someone invited to contribute photos to a family or wedding album doesn’t necessarily need a permanent account and profile just to complete that task. At Yogile, guests can contribute to shared albums without creating an account.

That reduces friction, but it also reduces the amount of identity data we need to collect and protect. After running Yogile for more than 15 years, I’ve become a strong believer that identity management should start by asking whether you actually need to identify the person at all.

Every identity you create becomes something you have to secure and maintain. Sometimes the safest identity record is the one you never needed to create.

 

Attach Expiry Dates to Elevated Grants

One damaging pitfall is designing identity governance around annual certification. A quarterly or annual review may satisfy a control requirement, yet modern teams change access through contractors, acquisitions, incidents, and fast product releases every week. By review time, the record can be accurate only as history, while unnecessary access has already become an operational dependency.

Treat identity changes as engineering changes with evidence attached at the moment they occur. I suggest requiring a reason, an accountable approver, and an automatic end date whenever access exceeds a standard role. Feed departures, team transfers, and dormant accounts into immediate removal workflows, then measure how long exceptions survive. This prevents temporary access becoming entrenched.

 

Maintain One Source for Business Details

The pitfall I see most often is treating identity as something you publish once, instead of something you maintain. A business prints its number, address and links on cards, standees, packaging and a handful of profile pages, and every one of those becomes a separate copy. The day something changes, most of those copies quietly go wrong, and the business usually finds out only when a customer says the number didn’t work.

The fix is to have one live source of truth and point everything else at it. Every printed card, QR code, NFC tag or bio link should open the same profile, so an update happens once and is reflected everywhere immediately. Before rolling anything out, I’d ask one simple question: if this detail changes next month, how many places will I have to fix? If the honest answer is more than one, the setup needs rethinking.

 

Formalize Urgent Access Paths

The common failure is configuring an identity platform around the happy path and discovering later that exceptions are the real operating model. Agencies routinely deal with urgent coverage, regional handoffs, client escalations, and short-term collaborators. If every exception requires an informal workaround, people will create parallel accounts or share access to keep work moving.

I would document the ten most frequent exceptions before launch, then design controlled routes for each one. A temporary access request should have an owner, a stated reason, an automatic expiry, and a reviewable record. This is more practical than imposing rigid rules that teams evade under pressure. Mature governance makes exceptions visible, bounded, and reversible.
