A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
The app is creating a loop because the same Microsoft Authenticator account is being used both as the sign-in method and as the thing being signed into. In this situation, a different verification method or an admin reset of MFA is required; the app itself will not show a code until the account is added/verified.
Use one of these paths:
- Use an alternative sign-in method (if configured)
- Try signing in with another method already on the account, such as:
- SMS/text code
- Email code to a backup email
- Another registered authenticator app or hardware token
- Once signed in, go to the security/MFA settings for the account and either:
- Add Microsoft Authenticator again, or
- Remove the old Authenticator registration and re-register it.
- If this is a work/school (Microsoft Entra / Microsoft 365) account
- If there is an IT/admin for the tenant:
- Ask the admin to reset MFA for the account in the Microsoft Entra admin center by requiring re-registration of multifactor authentication. After that, sign in and set up Authenticator from scratch using the QR code.
- If this is a business account and the user is the only admin and locked out:
- Contact Microsoft support by phone and ask for a ticket with the Data Protection team to reset MFA for the tenant admin, as described in the referenced answers. This is required when no other admin can reset MFA.
- If this is a personal Microsoft account and no other method works
- If no backup sign-in method (SMS/email/other) is available and Authenticator is the only method, account recovery must be handled by Microsoft support/Data Protection team via phone support. They can verify identity and reset MFA from their side.
Once MFA is reset or another method is used to get in, re-add the account to Microsoft Authenticator so that the app shows either push notifications or a “One-time password code” entry for that account.
