It sounds like you are experiencing issues with Multi-Factor Authentication (MFA). Here are a few steps you can try:
- Check Authenticator App Settings: Ensure that the Authenticator app is set up correctly and is generating the correct codes. Sometimes, re-syncing the time in the app settings can resolve issues with code mismatches.
- Alternate Verification Methods: If you have set up alternate verification methods (like SMS or email), try using those to log in.
- Account Recovery: Use the account recovery options provided by Microsoft to regain access. This might involve verifying your identity through security questions or alternate email addresses.
- Support Request: If none of the above steps work, you may need to contact Microsoft Support for assistance. They can help you regain access to your account.
