Microsoft authentication

Question

My Microsoft authentication is not working and I am not able to log into my outlook email

Answer 1

Use these steps to restore access, starting with Authenticator and then the Outlook account itself.

1. Check common Authenticator issues
   • Make sure the Microsoft Authenticator app is unlocked on the device.
   • Confirm notifications are enabled for Authenticator and that they are not set to silent. Also check SMS messages for any codes that may have arrived quietly.
   • Install the latest version of Microsoft Authenticator from the store to avoid issues caused by an outdated app.
   • Ensure the device has a working internet connection; if needed, switch between Wi‑Fi and mobile data.
   • Verify the device’s date and time are set correctly (automatic time is recommended).
   • If the sign‑in still fails because of credentials, use Reset your password and follow the prompts: Reset your password.
2. If Outlook sign‑in itself is failing
   • If the issue is with the Outlook mobile app, run the sign‑in helper tool for Microsoft personal accounts from the article and follow its guidance: Start.
   • If recurring password prompts appear, install or update to the latest Outlook mobile app: download the latest version.
3. If the password is not accepted or was recently changed
   • If the username or password stopped working, use the Recover your account flow and follow all steps to reset the password: Recover your account.
   • Ensure the correct email domain is used (for example, .com vs .co.uk) and that the email name is typed correctly.
   • If the primary email is not recognized, try another alias or phone number on the account.
4. If “Authentication did not complete” appears
   • Confirm Authenticator is unlocked, notifications are on, the app is updated, the network is working, and device time is correct, as listed above.
   • If the problem is forgotten credentials, use Reset your password from the same article.
5. If sign‑in is still not possible
   • If none of the above works and access to Outlook email is still blocked, use the account recovery and support options described in the account‑recovery articles (for example, the account recovery form and “I don’t have any of these” options when prompted for verification methods) and follow the on‑screen instructions until the account is recovered.
