KeePassX is a cross platform port of the windows application "Keepass Password Safe". It is an OpenSource password safe which helps you to manage your passwords in an easy and secure way. It uses a highly encrypted database locked with one master key.
What the Hell is going on with your forum? I mistakenly deleted a USB stick with KeePassX on it. I was able to recover the DB and Key but so far haven't been able to access it. Having access to the forum would most likely expedite my process!
I use KeePassX (2.0.3, currently), via dropbox, on three or four computers with ease. I also import the database to "MiniKeePass" (1.6.3, currently) on my iPhone (a slight hassle that I can live with, although an iPhone port of KeePassX would be ideal). I also use the "Notes" field copiously, to keep track of business details that are not strictly credential-related (such as name servers and account numbers). Thanks to the developers for creating this tool that imposes order on the chaos of using unique passwords for every web site!
