I use KeePass as my password manager which works very well on Windows. Running it on Linux is not as easy but it has gotten better over the years for example in 14.04. Integrating it into browsers on the other hand is the missing link. The post was based on Ubuntu 14.04 LTS
KeePass is still a Windows application running on .Net but now KeePass is part of the Ubuntu respository so to install it is like any other software:
sudo apt-get install keepass mono-complete
Go to KeePass tab and make sure the following at set:
Replace user with the username and xxxxxxx is made up of random letters and numbers and the .default means its the default password.
The plugin requires KeePassRPC.plgx file copied to the KeePass directory.
The instructions post KeeFox install can be found here. By default the file can be found in:
or what was set in KeePass options above for KeePassRPC plugin installation location.
Create a plugin folder and copy the file to the KeePass install directory:
sudo mkdir /usr/lib/keepass2/plugins
sudo cp /email@example.com/deps/KeePassRPC.plgx /usr/lib/keepass2/plugins/
where user is the name of the user.
After completing the above, restart Firefox and it will prompt for a one time password in Firefox and in turn launch KeePass to generate one.
If either has been upgraded it may require going through the above steps again. The difference is all the software is installed so it should just be the settings.
When upgrading make sure you close KeePass and restart Firefox. Check Keefox settings. Once done, go onto a site so that the Load KeePass database bar appears. Click on the button to open KeePass. When it loads, it should have a progress bar (albeit very quick). Enter you password / key file and the upgrade is done.
Ubuntu KeePass installation is not as straight forward as Windows but in the it works.
