Simple To Do List: Password Protection your Information
You've got a possibility to protect your database from unauthorized access by setting a password.
To do this you need to enter the dialogue [Tools | Options]
Then you should enable the checkbox "Password Protection". The "Change Password" button will be active if you already have a password, else the dialog opens automatically.
In the dialogue that comes up, enter your password twice.
After restart of the program and later on every time on the program's start you'll be asked to enter your password.
To remove the password from a database, call the [Tools | Options] dialog again and uncheck the "Password Protection" option.
