"Lock the application" and "Authentication password" should be the same setting
Currently, these are separate settings, which causes two problems:
- If you set a password but don't set the ability to lock the application, the application will not lock on startup as expected
- If you set the ability to lock the application, but close the window without setting a password, you won't be able to unlock the application again (without editing dconf manually)
It would be better to have an option to set a password and an option to clear it. If there is a password set, then the application can be locked, otherwise it cannot.
