A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
It sounds like the Authenticator app is not generating the verification code for your account. Here are a few things you can try:
- Ensure your phone's date and time settings are set to automatic.
- Check if the Authenticator app is up to date.
- Remove and re-add your Microsoft account in the Authenticator app.
- If you have backup codes, use one of those to log in and then troubleshoot the Authenticator app.
If these steps don't work, you may need to contact Microsoft support for further assistance.
