How to reset the master password if I forget it?

I forgot the master password, thus I can't change it. I wanna reset the master password so I wouldn't enter the password every time when login. Btw, if it's possible to disable the master password check function?

Start by reviewing the existing master-password and login behavior described by the issue, then locate the relevant implementation and any tests for password checks. Clarify whether recovery, changing the forgotten password, or disabling the check is intended; done should be a documented, tested behavior for the chosen scope.
