how to reset users that blocked by login using authenticator app

[Dr Atul G- LNG]

Resetting a user blocked by a login authenticator app typically requires an administrator to revoke the user's current Multi-Factor Authentication (MFA) device in the admin panel. This forces the user to re-register their app upon the next login. [1, 2, 3, 4]

Here are the specific steps for major platforms as of 2026.

Microsoft 365 / Entra ID (Azure AD) 

Admins can unblock users through the Azure portal or Entra ID center: 

1. Sign in to the Microsoft Entra admin center.
2. Navigate to Users > All users.
3. Select the user who is blocked.
4. Select Authentication methods.
5. Click Require re-register multifactor authentication.

Hi @Alon Grod 

• Navigate to User Setup: Go to Multi-Factor Authentication > User Multi-Factor Setup.
• Locate User: Search for the specific user blocked by the authenticator app.
• Unvalidate: Set the "Validated" flag to false.
