KeePass not only creates strong passwords, but it keeps track of them for you in an encrypted database using Advanced Encryption Standard (AES, Rijndael) and the Twofish algorithms. It will even enter your user name and passwords into a website with the shortcut key of CTRL+ALT+A. It knows which website by matching the titlebar with the entry title.

It works on more than just websites and has limited macro code that can be written to get around those (attempted) “Two Factor” logins. It gets confused since some websites use the same generic names in their titlebars (eg “Sign In”). With Firefox, You can overcome this limitation with the “Customize Titlebar” plugin and the “Auto-Type-Window” functionality of KeePass.
