Hi steve m clubley,
The fact that the account still works on the Android phone does not necessarily mean the Windows sign-in credentials are still valid, as the apps may be using an existing signed-in session. However, the “PIN isn’t available” message can also be a Windows Hello issue rather than a complete Microsoft account lockout.
As a first check, have your wife try signing in to her Microsoft account from a private or Incognito browser window on another device.
- If she can sign in there, return to the laptop’s sign-in screen, select Sign-in options, and choose the password icon instead of the PIN. Make sure the laptop is connected to the Internet. Once she is signed in, the PIN can be reset from Settings > Accounts > Sign-in options.
- If she cannot sign in online or the account is specifically reported as locked, use the official Microsoft Account Sign-in Helper. This tool can identify whether the issue involves the password, verification method, or an account lock and provide the appropriate recovery path.
When the verification prompt appears, please also check the partially displayed destination carefully. A security code will only be sent to a recovery email address or phone number already associated with your wife’s account. If the destination is unfamiliar or inaccessible, avoid repeatedly requesting codes and follow the recovery option shown by the Sign-in Helper instead.
I would not recommend resetting or reinstalling Windows at this stage, since this may introduce additional recovery requirements without resolving the account issue. Thank you so much for your understanding.
