A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
If you no longer have access to the Microsoft Authenticator app and are being asked for app approval to sign in, you will need to follow a few steps to regain access:
- Alternative Sign-in Methods: Check if there are any alternative methods available for signing in, such as SMS or email verification. If these options are available, use them to log in.
- Contact Support: If you do not have alternative sign-in methods, you will need to contact Microsoft support. Since you mentioned you are in a critical situation, it is advisable to reach out to the support hotline. When you call, follow the prompts to indicate that you are a business email user and need technical support. Make sure to explain that you are locked out due to the Authenticator app.
- Data Protection Team: If you are the only global administrator of your account, you may need to involve the Microsoft Data Protection team. They have the necessary tools to verify your identity and help you reset your multi-factor authentication (MFA) settings.
- Creating a Trial Tenant: As a workaround, you can create a trial Microsoft 365 tenant. This will allow you to access the Admin Center and submit a support ticket directly from there. Make sure to clearly state that you are locked out of your original account and provide all necessary details.
- Reset MFA: If you manage to contact support, they can assist you in resetting your MFA settings, allowing you to set up the Authenticator app again.
These steps should help you regain access to your account without the Authenticator app approval.
