Everyday we have a lot of passwords to manage corresponding to a lot of accounts we use. It's hard to remain all of these, moreover if we don't use it often. So, what we most people do is to generate only a subset of passwords easy to remain. This implies two common errors :
The best way to avoid these errors is to have a unique strong password for each account. gPass helps to reach this goal : you keep a subset of passwords and for each login/password tuple you chose, gPass returns the real password by querying a password server.
To have a high level of security, all information is stored encrypted. The decryption is done on the fly when it's needed and only with user input. So, a hacker can get your password database, it will not be able to see any information (except if it bruteforce your masterkey) !
This addon is like [last pass](https://lastpass.com/) one, but I wanted it to be open source and home hostable (be careful on server down !). Moreover, with gPass, you can have multiple master key !
The first thing to do is to populate your database (from your/a password server) with login/password/master key values. If you want to make strong password, there is a password generator. After that, configure your addon in addons -> gPass -> preferences to point to your password server (+ username).
When you're in a login form and you want to use gPass. Type your login and fill "@@masterkey" in password field. Then, submit and password willll automatically be replaced by the one in the database (after decryption).
