Q1. I am not receiving notifications from Microsoft Authenticator

Please check the following:

If notifications are not received, you can sign in using a verification code.

Steps:

1. Select “Sign in another way” or “Use a code”
2. Open the Microsoft Authenticator app
3. Check the 6-digit code
4. Enter the code on the sign-in screen

Please sign in using another method or re-register your authentication methods.
