Try these checks in order:

Unlock the Microsoft Authenticator app on the device first. If the app is locked, the entry box might not appear.
Make sure notifications are enabled for Microsoft Authenticator. Silent or disabled notifications can prevent the prompt from appearing. Also check text messages in case a code arrived silently.
Update Microsoft Authenticator to the latest version.
Check connectivity on the phone. If possible, switch between Wi‑Fi and mobile data.
Verify the phone’s date and time settings are correct.
If phone verification is failing, try another verification option if one is available.
Confirm the phone number and country/region code registered for verification are correct.
Review whether the phone blocks texts from unknown numbers, whether the inbox is full, or whether a messaging app problem is preventing SMS from appearing.
If many attempts were made recently, stop retrying repeatedly. Microsoft can temporarily block or limit verification attempts. Wait at least 24 hours, and in some cases longer, before trying again.

If this is a work or school account and the app still cannot be unlocked or codes still do not arrive, send logs from Authenticator using Send feedback in the app, then contact the IT admin. A Microsoft Entra administrator may need to unblock the user or reset authentication methods.

If this is a personal Microsoft account and the issue continues after the checks above, send logs from Authenticator using Send feedback in the app and use the sign-in helper or account recovery options if access to security info is lost.
