Thank you for reaching out to Microsoft Q&A Forum and sharing your experience.
I understand how confusing this can be, especially when a verification number is shown but the Microsoft Authenticator app never prompts you to approve it.
Please try the steps below on the phone that has the Microsoft Authenticator app installed:
- Open Microsoft Authenticator and pull down to refresh the account.
- Verify that notifications are enabled for Authenticator at the operating‑system level.
- Ensure Date & Time on the device is set to automatic.
- Disable battery optimization or power‑saving modes for the Authenticator app.
- Try signing in again while the Authenticator app is open in the foreground.

If this is a work or business account and the issue continues, please contact your tenant’s Global Administrator and ask them to follow this official Microsoft guidance to reset your multi‑factor authentication (MFA) settings so the Authenticator setup can be completed again.
If you are the only Global Administrator and are unable to sign in, you will need to contact Microsoft Support directly for account recovery. You can reach them by phone using the numbers listed here: Customer service phone numbers – Microsoft Support
If I have misunderstood your situation, please don't hesitate to clarify, and I will adjust my recommendations accordingly. I'm looking forward to seeing your response soon.
