You have forgotten the password of your laptop and now you can't access your device anymore ? Rest assured, this might solve your issue.

How to reset the password of your laptop

After entering a wrong password, click "Reset password", which will appear in white on your login screen. Answer the security questions you set up upon installing Windows and create a new password. Then, log in with your new password.
