A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Try these in order:
- Unlock Microsoft Authenticator on the phone first. If the app is locked, the box to enter or approve the sign-in may not appear.
- Check notifications for Authenticator:
- Open the phone settings.
- Go to Notifications for Microsoft Authenticator.
- Make sure notifications are allowed and not silent.
- Also check text messages in case a code arrived silently.
- Force close and reopen the app, then try the sign-in again.
- Check network connectivity:
- Switch from Wi-Fi to mobile data, or from mobile data to Wi-Fi.
- Make sure Airplane mode is off.
- If a VPN is enabled, disconnect it and test again.
- Update Microsoft Authenticator to the latest version. Versions older than 12 months are not supported.
- In Authenticator, open Settings and:
- turn on App updates
- select Turn off battery optimization
- open Notification Settings and make sure Show notifications is on
- Check the phone date and time and make sure they are correct.
- If the sign-in screen offers it, choose Use a different way to sign in, I don’t have my authenticator app, or another verification method such as SMS or email.
- If the account is a work or school account and the loop continues, complete the sign-in in Authenticator, Company Portal, or the primary Microsoft app on the device. If that still fails, contact the IT admin to reset or help with the sign-in method.
If the issue is specifically that the two-digit prompt never appears, the most relevant fixes are: unlock the app, enable notifications, and confirm the phone has a stable internet connection.
