Hi @杯莫停
Could you please tell me if you have tried to log into your Microsoft account using email verification, SMS verification, or phone verification?
- If you have set up other verification methods besides Authenticator (such as phone verification, SMS verification)-you can usually see a "Sign in with other methods" link on the login screen, please click to verify with other verification methods. Once the verification is successful, go to the "Other security verification" page, turn off Authenticator, and re-enable it later, see Change your two-step verification method and settings.
- If you are the only administrator in your tenant and have not set up other verification methods, in this case, if you have not logged out of your Microsoft 365 admin center, you can turn off multi-factor authentication (MFA) yourself and re-enable it later; if you have logged out of your Microsoft 365 admin center before, you must call technical support, see Phone support, and let them help you unlock your account. Find support phone numbers by country or region
Thanks for your understanding and support.
