A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
If Microsoft Authenticator is not showing the code, try these steps in order:
- Check whether the prompt or code is going to an older phone. If Authenticator was previously active on another device, the notification may still be sent there. If that old device is available, open Authenticator on it and approve the sign-in.
- On the current phone, make sure the Authenticator app is unlocked.
- Verify notifications are enabled for Microsoft Authenticator. Silent or disabled notifications can prevent the prompt from appearing.
- Make sure the app is updated to the latest version. Microsoft does not support Authenticator app versions more than 12 months old.
- Check connectivity. Switch between Wi‑Fi and mobile data, make sure Airplane mode is off, and if a VPN is enabled, disconnect it temporarily.
- Check the phone date and time settings and make sure they are correct.
- In Authenticator, open Settings and turn off battery optimization if that option is available.
- If the sign-in page offers another verification method, use it instead, such as SMS.
If the account is a personal Microsoft account, another recovery path is to use the security settings page to set up the identity verification app again: security settings page.
If none of the steps work, send Authenticator logs from the app by opening the top-level menu and selecting Send feedback. After that, contact Support for a personal account.
