Windows Hello Your password was changed on a different device Windows 10
The said message is not an error. It’s just an info telling you that your account password was changed on a different device. To overcome the error, you must first understand the problem.
The PIN or biometric gesture such as face recognition, fingerprint recognition or iris recognition you’ve set up in Windows Hello will be tied to the specific device. You account’s password, however, is server specific. You can set up Windows Hello for the same account on multiple devices.
So, if you have recently changed your Microsoft account’s password on a different device, the other devices which use the same account won’t recognize the password changes and will show you the error: Your password was changed on a different device.
For example, assuming you are using the same Microsoft account on computer A and computer B and have set up a PIN or biometric gesture for both of the computers. If you change your password on computer A, the next time you see Windows Hello on computer A, you will be able to login via PIN or biometric gesture. If you are on computer B and you try to sign in using your PIN on Windows Hello, it will fail and show the “Your password was changed on a different device” message because it couldn’t recognize the password change that was made on computer A. It also applies to Windows 10 mobile device and laptop that uses the same account.
