LessPass

An open source password generator. Rather than store all your passwords it re-generates them each time using a master password and other criteria that you already know. It does this in a way that guarantees the same password for any particular site. Features ability to select upper or lower case, special characters, length and a counter that allows you to create a new site password without changing your master password. Provides access via home site or use Chrome or FireFox extensions. Allows hosting on your own server.
