i cant get a auth number on my phone with authenticator \after my new phone

Hello, thank you for reaching out to Microsoft Q&A.

Do you still have your old device with you? If so, you can use it to access the Authenticator app. If you’ve switched to a new device, install the Authenticator app on that device and follow the steps provided here to successfully add your account to the app.

Did you back up your account credentials to a recovery account before you switched to a new mobile device?

If you previously added a recovery account, select "Start Recovery" in the Authenticator app and enter your recovery account credentials before signing in.

Enter the recovery email address and Password.

1• You'll be prompted to verify your identity through the Authenticator app.

2• Select "I can't use the Authenticator app right now" or choose "Show more verification methods."

3• You can then use alternative verification methods, such as your phone number or email address, to confirm your identity.

Sometimes you may be prompted to reset your password. After the reset, select "Start Recovery" again and add your account to the Authenticator app.
