Question details

The user forgot their PIN for the Microsoft Authenticator app and needs to unlock it or reset their authentication methods to access their accounts.

Product: Microsoft Authenticator
Device & OS: not provided
Scenario: Trying to approve a sign-in request or access secured accounts but locked out of the Authenticator app due to a forgotten PIN.
Observed behavior: The app prevents access and stops the user from verifying logins because the correct security PIN cannot be entered.

Before you start

Verify whether the Microsoft Authenticator app is linked to a personal Microsoft account or an organizational (work or school) account, as the recovery steps differ significantly based on the account type.

Solution 1Recommended

Contact Your IT Administrator (For Work or School Accounts)

If you are using an educational or corporate account, your organization's IT department is the only entity authorized to reset your MFA settings.

For security reasons, users cannot independently bypass or reset the PIN on managed corporate or educational accounts without administrative intervention.

Identify IT support

Locate the contact information for your school's IT helpdesk or your company's network administrator.

Request an MFA reset

Contact the admin and request them to 'Reset multifactor authentication' or 'Require re-register MFA' for your specific user account.

Set up Authenticator again

Once the administrator clears your previous settings, open your Authenticator app, add your work or school account, and follow the on-screen prompts to scan the new QR code.

Important: Microsoft support cannot reset MFA settings for organizational accounts. Only your internal IT administrator has the permissions to do this.

Solution 2

Recover Using Account Backup (For Personal Accounts)

If you previously enabled Cloud Backup for your personal Microsoft account, you can recover your credentials by reinstalling the app.

Solution 3

Consult the Microsoft Authenticator Q&A Forum

If standard recovery steps fail, seek targeted guidance from Microsoft experts in the official support forums.

Frequently Asked Questions

Can I bypass the Microsoft Authenticator PIN if I forget it?

No, for security reasons, the PIN cannot be bypassed. You must either recover your accounts from a cloud backup (for personal accounts) or have your IT administrator reset your multi-factor authentication (for work/school accounts).

Will reinstalling the Authenticator app remove my accounts?

Yes, uninstalling the app will wipe the current accounts stored on it. You must have a cloud backup enabled previously to restore personal accounts smoothly, otherwise you will need to re-register each account manually.

What happens if I don't have an IT admin for my personal account?

If it is a personal Microsoft account, you can use alternative verification methods (like a backup email or SMS text message) to sign into your Microsoft account online. From there, you can navigate to your Security settings to remove the old Authenticator app and set up a new one.
