Introduction
------------
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 :
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 most people do is to generate only a subset of passwords easy to remain. This implies two common errors :
* Password are not very strong
* We use them for multiple accounts
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) !
To have a high level of security, all information is stored encrypted (server side). Nothing is stored on client. 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 !

Usage
-----
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).
