A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Try these steps in order:
- On the sign-in screen, select Other ways to sign in and then Approve a request on my Microsoft Authenticator app if that option appears.
- Open Microsoft Authenticator on the phone and make sure the app is unlocked. If the app is locked, the number entry box may not appear.
- In Authenticator, pull down to refresh or tap Refresh. Some sign-in requests do not generate a notification automatically, and the request must be refreshed inside the app.
- If a number is shown on the computer, enter the matching number in Authenticator and tap Approve.
- If notifications are silent or disabled, enable notifications for Microsoft Authenticator. Silent or disabled notifications can prevent the prompt from appearing.
- Make sure the phone has internet access. If needed, switch between Wi-Fi and mobile data.
- Check that the phone’s date and time are correct.
- Update Microsoft Authenticator to the latest version.
If approval still does not work:
- Try Use a verification code if that option is offered during sign-in. The app can generate an OATH verification code that can be entered manually.
- If this is a work or school account, an administrator can require MFA re-registration for the account so Authenticator can be set up again.
- If another sign-in method is available, select I don’t have any of these and follow the prompts to add or verify security info.
- If no codes are arriving and no alternate method works, use the Sign-in helper or Contact Microsoft Support. Support agents cannot send verification codes or change account details.
For remote computer setup with a work or school account, Authenticator also supports Sign in from another device, but that feature works only if the admin has enabled remote sign-in.
