Hi, this usually happens because of a small setting on the phone, so please try these steps one by one:
- Fix the phone time. Go to your phone settings and set Date & Time to “Automatic”. If the clock is even a little wrong, the code from the app gets rejected.
- Check notifications. Allow notifications for Microsoft Authenticator, turn off battery saver for the app, and make sure Do Not Disturb is off.
- Update the app. Get the newest version from the Play Store or App Store, and make sure your internet is working.
- Enter the code manually. Authenticator doesn’t send SMS. Open the app, find your account, and type the 6-digit code that is shown there. It changes every 30 seconds, so type it quickly.
- Try another way to sign in. On the sign-in page, click “I can’t use my Microsoft Authenticator app right now” and choose another option, like email or a phone number, if you added one before.
If it’s a work or school account, your IT admin can reset your sign-in method. Let us know if it still doesn’t work.
