Account sign in issue with authenticator

Question

I am unable to sign into one of my accounts. I can't generate a code that works in authenticator. When I am in the authenticator app, it asks to verify a code that is never generated.

Answer 1

Follow these steps to resolve the sign-in loop where Authenticator asks for a code that never appears or never works:

1. Check for the “Authentication did not complete” causes
   • Make sure the Microsoft Authenticator app is unlocked when trying to approve or enter a code.
   • Confirm notifications are enabled for Authenticator on the device and not set to silent, so prompts are visible.
   • Ensure the app is updated to the latest version.
   • Verify the device has a working internet connection (try switching between Wi‑Fi and mobile data).
   • Confirm the device date and time are set correctly (automatic time is recommended).
   If any of these are wrong, the app may never complete the verification and can appear to be “waiting” for a code that doesn’t show.
2. Try an alternate verification/sign-in method
   • On the sign-in screen, look for options like “Use a different verification option”, “I don’t have a code”, or “I can’t use my authenticator app right now” and select another method (SMS, email, backup method) if available.
   • If verification codes are not arriving (SMS/email), follow the guidance in the verification-code troubleshooting article: check junk mail, phone SMS blocking, VOIP numbers, and avoid repeated requests that can cause a temporary block.
3. If the account is a work or school account
   • If there is another sign-in method configured (SMS, email, security key), use that to sign in.
   • If no other method works, contact the organization’s IT admin/Help desk and ask them to reset MFA / require re-register multifactor authentication for the account in the Microsoft Entra admin center. After they do this, sign in again and re-register Authenticator from scratch.
4. If the account is personal and no method works
   • Use the sign-in helper to diagnose sign-in issues and see available recovery options.
   • If still blocked and no verification method is usable, contact Microsoft Support via the Contact Microsoft Support page and follow the prompts to get routed to the appropriate support option. Support cannot send codes or change security info directly, but can guide through the allowed recovery paths.

If the app is simply not showing any one-time password (OTP) for this account at all, and there is no alternative method and no admin who can reset MFA, the only resolution path is through Microsoft support/data protection processes as described in the referenced articles.
