How do I unblock sign in

If the PC is blocked at sign-in, use the recovery options available on the Windows sign-in screen first:

1. At the sign-in screen, select I forgot my password if the account uses a Microsoft account.
2. If using a PIN, select I forgot my PIN.
3. Enter the Microsoft account password if prompted. For a Microsoft account, the Windows password is the same as the Microsoft account password.
4. If Windows Hello is configured, try another sign-in method such as password instead of PIN.
5. If the account was blocked because of unusual sign-in activity, follow the instructions on the sign-in screen and choose where to receive a security code. Enter the code to unlock access.

If the blocked sign-in is for an Outlook.com or Microsoft account:

1. Use the Sign-in Helper: https://aka.ms/sign-in-helper
2. If sign-in was blocked due to unusual activity, complete the security code verification or change the password.
3. If traveling or using a new device, try signing in from a trusted device or a usual location.

If the account is a smart card sign-in and the PIN is blocked on Windows 10, try one of these before signing in again:

1. Restart the computer.
2. Sign in using another method such as username and password.
3. Sign in with another account, then sign out.
4. Try the blocked smart card on another computer.
