You can try the following steps to resolve this issue:
- Uninstall the Microsoft Authenticator app from your device.
- Clear your browser cache and cookies.
- Reinstall the Microsoft Authenticator app.
- Sign in to your account using your email address and password.
- Follow the prompts to set up the Microsoft Authenticator app.

If this doesn't work, you can try resetting your password and then setting up the Microsoft Authenticator app again.
I hope this helps.
Kind regards,
Jayzar
