Authenticator login

Question

I am trying to sign in to my authenticator app but I can't get the code from the authenticator app while trying to sign into the app

Answer 1

The code to complete sign-in does not come from signing in to the Authenticator app itself. Instead, use one of these supported flows:

1. Use push notification from Authenticator
   1. Go to the site or app where the account is being signed in.
   2. Enter the username and select Next.
   3. Choose Send notification (or Other ways to sign in → Approve a request on my Microsoft Authenticator app).
   4. When prompted to Check your Authenticator app, open Microsoft Authenticator on the phone.
   5. Approve the sign-in (or enter the number shown on the sign-in screen) inside Authenticator.
2. Use a verification code from Authenticator
   1. On the sign-in page, first enter username and password.
   2. When asked for the second step, choose the option to use a code from the authenticator app (for example, Use a verification code or Use a code instead).
   3. Open Microsoft Authenticator, tap the account, and use the One-time password code shown there.
   4. Enter that code into the Enter code box on the sign-in page.
3. If “Authentication did not complete” or no prompt appears Check the common causes:
   1. Make sure the Authenticator app is unlocked so the approval box can appear.
   2. Confirm notifications are enabled for Authenticator and not set to silent.
   3. Update Authenticator to the latest version.
   4. Ensure the phone has a working internet connection (try switching between Wi‑Fi and mobile data).
   5. Verify the device date and time are correct.
4. If the notification is going to an old phone
   1. If an older device still has Authenticator installed, the push may be going there. Check that device and approve from it if possible.
   2. If the old device is not available, use another verification method offered on the sign-in screen (such as SMS or phone call) to get in and then remove the old device from the account’s security info.
5. If completely locked out If no alternative method (SMS, phone call, backup email, or another admin) is available and access to Authenticator is lost, the account’s admin or Microsoft’s Data Protection team must reset MFA from their side. For work/school tenants where the locked-out user is the only admin, this must be done via Microsoft support.
