! - USER CANNOT SIGN IN - MFA

[tianaranjo]

Greetings, 

I have shared an app with a user. When she tries to sign into Power Apps, she either:
1. Keeps getting redirected in MFA to approve login OR

2. Is directed back to the sign in screen getting Session ID 163f80c0-9a29-4e7f-bd39-2ebb4581cc76 error

I am preparing to release this app to ~100 users and would like to resolve this issue and determine the cause in an effort to avoid this with others.  

Immediate attention and response would be greatly appreciated.

Sorry to hear that your users are facing authentication issue. We have seen issues where if user had accidentally logged in with a personal account, they are no longer able to login again. We have also seen issues related to the Microsoft Authenticator app not responding properly, causing authentication failure. Some of these failures have also happened due to system restrictions for Android devices (See here.)

In most cases, uninstalling and reinstalling both 'Power Apps' and 'Microsoft Authenticator' app will resolve the issue.

Please have your user follow the steps below and let us know if it helps:

1. Back up your 'Microsoft Authenticator' accounts
2. Uninstall 'Microsoft Authenticator'
3. Uninstall 'Power Apps'
4. Reboot the device
5. Reinstall 'Power Apps'
6. Reinstall 'Microsoft Authenticator', add back your accounts
7. Try to sign in to 'Power Apps' again
