MFA Re-Registration with Temporary Access Pass

Users regularly lose access to their MFA method — replaced phone, factory reset, uninstalled Authenticator, or a registration that never completed. Without a fallback, they can't sign in to MFA-protected enterprise apps.

Restore sign-in quickly without weakening identity assurance — verify the human, avoid a lingering bypass, and leave the user on a working MFA method they own.

• Verified user identity through the enterprise-approved out-of-band check.
• Coordinated a Temporary Access Pass scoped to the re-registration window.
• Walked the user through Microsoft Authenticator install and re-enrollment.
• Validated MFA sign-in against a protected app before closing the ticket.
• Documented the resolution in ServiceNow.

1. 01

   Verify identity out of band

   Confirm the human on the other end using the approved verification path — not the compromised channel.

2. 02

   Coordinate a Temporary Access Pass

   Have a short-lived, one-time-use TAP issued for the re-registration window per the enterprise process.

3. 03

   Guide Authenticator re-enrollment

   Install the app, add the account, complete number-matching, and confirm the notification loop.

4. 04

   Validate end-to-end sign-in

   Sign the user into an MFA-protected app to confirm the new method works.

5. 05

   Document in ServiceNow

   Record the pattern so the next occurrence is faster for any technician.

Verification paths, TAP lifetimes, and app names are intentionally omitted.

Users are signing in again in minutes on a method they control. The ServiceNow record makes the next occurrence faster for any technician.

• Working knowledge of Entra ID authentication methods and Temporary Access Pass.
• Discipline around identity assurance during account recovery.
• Comfort operating in the identity plane where enterprise access actually breaks.
