If you demand security for your personal data, then KeepassX is one of the best manager for you. KeepassX is a open source software under the GNU GPL, is cross-platform, with an easy to use interface.
You can generate secure passwords using the fast and simple, customizable password generation utility that comes built into KeepassX.
Using KeepassX is easy and intuitive, but I always recommend going through a tutorial before installing a new, unfamiliar software; you can view one such document by clicking here. Since I’ll be telling you how to install KeepassX on Debian 8.X Linux, you can overlook the Debian KeepassX white paper if you so choose.
I consider Debian Linux to be the most stable of all Linux distributions, and has an excellent balance of security and user interface properties. That being said, here is all you need to do to install KeepassX on Debian 8.X Linux:
Open a terminal window and type:
sudo apt-get install KeepassX
That’s all there is to it. Now you can generate and save all of your password, and usernames in the KeepassX 256-encrypted database, and retrieve them using a master password.
