Entra ID Hygiene: A Quarterly Checklist for Growing Businesses

Your identity system quietly accumulates risk as your business grows. Use this quarterly Entra ID hygiene checklist to clean up accounts, roles, and access before they become findings.

As a business grows, its identity system grows with it, and not always neatly. Accounts get created, guests are invited, applications are connected, and roles are handed out. Very little of this ever gets cleaned up on its own. Over time, your Entra ID environment becomes a record of every decision you ever made, including the ones you have long since forgotten.

Because identity is the foundation of everything else in your cloud environment, letting it drift is how small gaps become audit findings. A short, disciplined quarterly review keeps it healthy. Here is what to look at each time.

Stale accounts and lingering guests

Start with the accounts that should no longer exist. Former employees, contractors whose engagements ended, and test accounts created for a one-time need all accumulate quietly. Guest accounts are especially easy to lose track of, because they were invited for a specific purpose that has usually long since passed.

• Identify accounts that have not signed in for an extended period and confirm whether they are still needed.
• Review every guest account and remove those whose reason for access has ended.
• Confirm that departed staff and finished contractors are fully disabled, not just forgotten.

Unused app registrations and their secrets

Every application you connect to your environment leaves behind a registration, and many of those hold secrets or credentials that grant access. Applications you stopped using rarely get cleaned up, which means live credentials can sit unwatched for years.

Review your app registrations, retire the ones no longer in use, and pay particular attention to any secrets or credentials that are old or unnecessary.

Review privileged roles

Administrative access should be rare, deliberate, and current. Over time, people get elevated for a specific task and never get lowered again. The result is more administrators than the business actually needs, which widens the blast radius if any one account is compromised.

Confirm that every person with a privileged role still requires it, and remove standing administrative access that is no longer justified. Fewer administrators, each genuinely needed, is a stronger position.

Conditional access and legacy authentication

Conditional access policies are how you control where and how people sign in, but coverage gaps creep in as new accounts and applications appear. Check that your policies actually cover everyone and everything they should, with no accidental exceptions.

At the same time, hunt for legacy authentication remnants. Older protocols that bypass modern protections are a favorite target, and they tend to linger long after they are needed. Microsoft has been enforcing mandatory multi-factor authentication for signing in to Azure administration portals since late 2024, which reflects the broader direction: modern, enforced authentication is now the baseline expectation, and old sign-in methods are a liability.

Test your break-glass accounts

Most organizations create emergency access, or break-glass, accounts so they are never locked out of their own environment. Far fewer ever test them. An emergency account that does not work when you need it is worse than none, because it creates false confidence.

• Confirm your break-glass accounts exist and are properly excluded from policies that could lock them out.
• Verify their credentials are stored securely and known to the right people.
• Actually test that you can sign in with them, on a schedule, before you ever need to.

Make it a standing routine

None of these checks are difficult, but they only work if they happen on a rhythm. Put a recurring quarterly review on the calendar, work through this list each time, and document what you changed. The documentation itself becomes useful evidence of diligence if you are ever examined.

A managed services partner can help you sequence this work, but the habit is the real value. Clean identity is quiet identity, and quiet is exactly what you want here.
