Frequently Asked Questions
What should I do if my Microsoft Authenticator codes are being rejected?
This often occurs if your phone's clock is slightly out of sync. Go to your device's system settings and ensure the date and time are set to update automatically from the network.
Can I bypass the Authenticator app if I cannot sign in?
Yes, if you previously set up alternative verification methods (like an email or phone number), click 'Sign in another way' on the login screen to receive your verification code via SMS or email instead.
Why did I lose my Microsoft Authenticator accounts after switching phones?
Authenticator accounts do not transfer to a new device automatically unless you enabled cloud backup on your old device. Without a backup, you must use alternative recovery methods to sign in and manually re-add the accounts to your new phone.
