What is the difference between Passwords, Access Keys and Activation Keys?

Passwords are used to encrypt or hide files.

If you have many passwords, you can store all of them in a list, open with one “master password”. That master password is called Access Key (to a list of passwords).

Activation Keys are useful only to those that want to develop their own encryption algorithms or new carriers. It’s an internal security system of east-tec InvisibleSecrets.
