The long term solution would be to see 100% adoption of OpenID. Inevitably many sites will always be behind the curve, so until that day comes, I recommend Revelation.

Revelation is an easy to use, secure and lightweight password manager for Linux. It is written in GTK so those running the GNOME desktop (the default for Ubuntu) will be right at home. You can have several different folders to help organize your passwords, and define actions based on the type of password being stored.

A picture is worth a thousand words, so here is a screenshot of Revelation in action:

What makes this great is that all of your passwords are stored encrypted. This means if someone takes your computer, without your master password your passwords would be useless. This also means we can store our password using Ubuntu One or Dropbox.

If you are curious about Dropbox I wrote a post with screenshots showing exactly how it works. Simply save your Revelation password file there, and all of your systems that have Dropbox will now have access to those passwords (once you unlock it for that session of course).

Under the preferences window in Revelation you can also adjust your default password size (when you use Revelation you simply randomly generate a new password for each website) for as long as you need, with the longer the better.

If you are running Ubuntu, you can install Revelation by clicking Applications -> Ubuntu Software Center and searching for Revelation. If you would prefer the command line version:

# sudo apt-get install revelation

There are many alternatives out there, but if you are running Linux and just need a simple, no-hassle password manager Revelation is worth five minutes to try it out.
