On a different PC, Windows Hello options (PIN, fingerprint, face, passkey) are tied to that specific device and account. To sign in to Microsoft Store with an account that has no PIN/Hello set up on that PC, use the password sign-in path and, if needed, reset the password or set up a new PIN on that device.
Use these steps on the Windows 10 PC:
- On the sign-in prompt where it asks for PIN/Hello, look for Sign-in options.
- Choose the option to sign in with password instead of PIN/Hello.
- Enter the Microsoft account password.
- If the password is not known, reset it:
- On the sign-in screen, select I forgot my password and follow the prompts, or
- From another device, go to Reset password as described in the documentation.
- After successfully signing in with the password, optionally set up a PIN on this PC:
- Open Settings > Accounts > Sign-in options (or use the Sign-in options shortcut).
- Under PIN (Windows Hello) select Add or Change PIN and follow the instructions.
If Windows Hello keeps forcing a PIN that does not exist or fails repeatedly, sign in with the password first and then remove/recreate the PIN from Settings > Accounts > Sign-in options as described above.
