The Lock function is one of Password Depot's most important local security features: It allows you to safely leave Password Depot running on your computer without having to bother that someone could take a look at your database.
If you lock the program, this moves the application into the tray bar and in this way secures ('locks') it. The Lock function can be found at two places:
in the toolbar on the Home tab,
in the top bar.
To restore the application, you must enter the authentication method of the currently opened file - i.e. its master password and/or key file:
Click on the tray bar icon of Password Depot.
A window opens asking for the file's authentication.
Enter the master password and/or select the path to the key file.
NOTE: If you have entered a wrong master password and/or selected a wrong key file, you will receive an "Invalid master password/key file" error message. The application will be locked briefly. Afterwards, you can re-enter the master password and/or re-select the key file.
Click the OK button.
NOTE: As long as the application is locked, you can not perform any actions: neither edit the presently opened list, nor add a new list, nor open a different list. This may seem annoying, but only this guarantees the highest security standards possible on your computer.
