problem verify my authenticator account

Question

Answer 1

Follow these steps depending on what is happening when trying to sign in with Microsoft Authenticator.

1. If the message is “Authentication did not complete”:
   • Make sure the Microsoft Authenticator app is unlocked when trying to approve a sign‑in.
   • Check that notifications are enabled for Authenticator and not set to silent. Also check SMS messages for any codes that may have arrived quietly.
   • Confirm the app is updated to the latest version from the store.
   • Make sure the phone has a working internet connection; if needed, switch between Wi‑Fi and mobile data and try again.
   • Verify the device date and time are set correctly (prefer automatic time).
   • If the problem is actually a forgotten password, use the Reset your password option provided in the sign‑in flow.
2. If the message is “Authenticator did not complete login” or similar:
   • Complete the login in Microsoft Authenticator, Company Portal, or the primary Microsoft app on the device when prompted.
   • If the password is forgotten or sign‑in still cannot be completed, contact the IT administrator for the work or school account to reset MFA or provide another method.
3. If unable to sign in after many attempts:
   • Too many failed attempts can temporarily block sign‑in for security reasons. Wait and try again later, or use a different MFA method (SMS, phone call, alternate app) if available.
   • If this is a work or school account, ask the IT administrator to review Microsoft Entra sign‑in logs and, if needed, reset MFA methods.
4. If access to the Authenticator app was lost because of a new or reset phone and this is a work/school account:
   • If there is another global admin in the tenant, that admin can require a re‑register MFA for the user so new methods can be set up.
   • If this is the only admin account and there is no other way to approve sign‑in, contact Microsoft via the Customer service phone numbers and ask for the Data Protection team to help reset the authentication methods for the tenant admin account.

If none of these options work and this is a business/tenant admin scenario with no other admins, recovery must be done through Microsoft support (Data Protection team) as described above.
