Several IT-people in higher education has recommended KeePass for keeping track of keys and credentials. KeePass is a free open source password manager. You can put all your passwords in one database, which is locked with one master key or a key file.

They claim to be very happy about the way that wallet works. Of course this carries the usual risks you get when you put all your eggs in the same basket

  • nice target for hacking attempts
  • if you lose one key, you lose all keys
  • software is only secure as long as it is patched
  • remembering the single key that will unlock all keys

On the other hand, in addition to the benefits of an open source transparent solution you also get the usual benefits from putting all your eggs in the same basket

  • being able to find your keys
  • awareness of having a basket
  • easier to secure the one key to bind them all
  • you are more likely to discover if there has been an incident with your keys

Key wallets of this kind, including KeePass and PasswordSafe, seem to be better implemented than the password wallets found in browsers.
