Không đăng nhập được ondrive do không nhận mã authenticator

To regain access to your OneDrive account after resetting your phone and losing access to the Microsoft Authenticator app, you can follow these steps:

1. Alternative Sign-In Method: If you have any alternative sign-in methods set up (like SMS or email verification), try using those to log in.
2. Contact Your Administrator: Since you mentioned you are having trouble with Multi-Factor Authentication (MFA), if this is a business account, contact your organization's admin. They can reset your MFA settings through the Microsoft Entra Admin Center, which will allow you to set up the Authenticator app again.
3. Microsoft Data Protection Team: If you are the only administrator and cannot access your account, you will need to contact Microsoft’s Data Protection team. You can find the appropriate customer service phone numbers for your region and request assistance to reset your MFA settings. Be prepared to verify your identity.
4. Create a Temporary Account: As a last resort, you can create a new trial tenant to submit a support ticket to Microsoft on behalf of your original account. This will allow you to communicate with support and explain your situation.

These steps should help you regain access to your OneDrive account and retrieve your data.
