If Microsoft Authenticator gives a code, and the computer provides a code there is no place to enter a code. No instructions, but blocked for 24 hours.....

When a number appears on the PC saying to “plug this number into your Microsoft Authenticator,” it is usually asking to approve the sign-in in the Authenticator app, not to type that number back into the PC.

From the available information, the main issues and actions are:

1. No place to enter a code in Authenticator
   • Microsoft Authenticator is a mobile app that shows verification prompts and one-time codes for each account.
   • If only another company/account appears in the app and there is no Microsoft account entry, then the Microsoft account was never added to Authenticator.
   • In that case, the app cannot display a code or prompt for that Microsoft account, so the PC’s “enter this number in your Authenticator” step cannot complete.
2. “Authentication did not complete” / blocked after too many attempts
   • If the app is locked, notifications are disabled, the app is out of date, or the device has network/time issues, authentication can fail and eventually trigger a temporary block.
   • Blocks can also occur after many repeated attempts or unusual activity; the service may then show messages like “Try another verification method” or temporarily block sign-in.
3. What to do next time
   • Ensure Microsoft Authenticator is installed on the phone from the official store (Apple App Store or Google Play) and updated to the latest version.
   • Add the Microsoft account to the app first, following the “Add your accounts to Microsoft Authenticator” guidance. Once the account is present, the app will show either:
     • A push notification asking to approve the sign-in and match a number, or
     • A “One-time password code” that can be used where requested.
   • If a block occurs (for example, after many failed attempts):
     • Use another verification method already on the account (SMS, alternate email) if available.
     • Avoid repeated attempts; wait at least 24 hours before trying again, as repeated retries can extend the block.
     • Try another network (switch between Wi‑Fi and mobile data) if network issues are suspected.

If the Authenticator app still does not show any Microsoft account or one-time password code, and no alternate verification method works, recovery may require working through Microsoft’s sign-in helper or support paths referenced in the documentation.
