How to Fix Microsoft Authenticator Loop After Clearing App Data
Question details
The user is trapped in a multifactor authentication loop and cannot sign in or reconfigure the app because they cleared the app data.
- Product
- Microsoft Authenticator
- Device & OS
- not provided
- Scenario
- Trying to sign into a Microsoft account or re-add the Authenticator app after clearing app data without having a backup verification method configured.
- Observed behavior
- The sign-in process repeatedly requests MFA approval from the Authenticator app that the user is currently trying to set up, creating an inescapable login loop.
Before contacting support, click 'Sign in another way' on the login screen to see if you previously configured an alternative verification method, such as a text message or a secondary email address.
Request an MFA Reset from Your IT Administrator
Since you do not have a backup verification method, only a network administrator can break the loop by unregistering your previous device token.
When you clear the data of your Microsoft Authenticator app, the local security token is destroyed, but the Microsoft Entra ID server still expects approval from it. To resolve this, the server-side registration must be wiped so you can start fresh.
Reach out to your organization's IT help desk or Microsoft Entra ID administrator via phone, email, or your company's support portal.
Ask the administrator to find your profile in the Microsoft Entra ID portal and remove or unregister the old Authenticator device.
Have the administrator select the 'Require re-register MFA' option for your specific user account.
Once the admin confirms the reset, attempt to sign in to your Microsoft account. You will now be prompted to set up the Authenticator app as if it were a brand-new device.

Frequently Asked Questions
Why does Microsoft Authenticator ask for approval from itself?
This loop happens because the organization's server still considers your cleared app as the primary MFA device. Since the app data was erased, it lost its registration token, but the server doesn't know that and continues sending prompts to the missing token.
Can I recover my Microsoft Authenticator accounts without an admin?
You can only recover it yourself if you previously enabled cloud backup within the Authenticator app and have access to the recovery account, or if you set up an alternative sign-in method like an SMS phone number.
Does uninstalling the Authenticator app remove the account registration?
No, uninstalling the app or clearing its data only removes the local credentials from your physical device. The account registration remains active on your organization's server until an admin manually revokes it.
