Frequently Asked Questions

Why is my Microsoft Authenticator code suddenly being rejected?

The most common reason for a rejected code is a time synchronization issue. If the internal clock of your mobile device is off by even a few seconds compared to Microsoft's servers, the generated codes will be invalid. You can fix this by syncing the time within the app's settings.

Can I update my Microsoft 365 payment method without using the Authenticator app?

Yes, usually. When prompted for a code, click 'Sign in another way' or 'I can't use my Microsoft Authenticator app right now'. If you have set up alternative verification methods (like an SMS number or backup email), you can choose to receive your code through one of those channels instead.

Will a rejected Authenticator code lock my Microsoft account?

Entering an incorrect or rejected code multiple times can temporarily lock your account to protect against unauthorized access. If your codes are consistently failing, stop attempting to enter them and post your issue on the Microsoft Q&A forum for assistance.
