Microsoft authentificator & webmail

Question

My microsoft authentificator app doesn't work, I have 2 emails registered with the app, and any time I try to identify myself with the app, it never works, highly annoying.
And now i can't log into one of my emails on my laptop or other devices that are not my phone, because when i enter my password and i asks for further identification, I of course can't use the app made for that for whatever reason, and when I ask to receive a text on my phone number, that doesn't work anymore either.

Answer 1

For a personal Microsoft account, try these checks first in Microsoft Authenticator:

1. Make sure the app is unlocked on the phone.
2. Turn on notifications for Microsoft Authenticator. Silent or disabled notifications can prevent the prompt from appearing.
3. Update Microsoft Authenticator to the latest version. Versions older than 12 months are not supported.
4. Check network connectivity. Switch between Wi-Fi and mobile data, and make sure Airplane mode is off.
5. Verify the phone’s date and time are correct.
6. If a VPN is enabled, disconnect it and try again.
7. In Authenticator, open Settings and make sure battery optimization is turned off and notifications are enabled.

If the app shows "Authentication did not complete", these are the documented causes: app locked, silent notifications, outdated app version, network issues, incorrect device date/time, or needing a password reset.

For the sign-in problem when SMS also no longer works:

1. Do not make excessive or repeated code requests, because that can temporarily block code delivery.
2. Check whether the phone blocks texts from unknown numbers.
3. Make sure the phone inbox is not full and the messaging app is working normally.
4. If another verification method appears during sign-in, use it.
5. If the account password is no longer accepted, use the account recovery flow and reset the password.

If Authenticator still fails after those steps, send logs from the app:

• Open Microsoft Authenticator
• Open the app’s top-level menu
• Select Send feedback

After that:

• For a personal account, contact Support or use the Microsoft Authenticator app forum.
• For a work or school account, reach out to the IT admin.

If repeated sign-in attempts were made, Microsoft Entra multifactor authentication can temporarily block more attempts. In that case, wait and try again later, or use a different MFA method if one is available.
