I can vouch for 1Password as well. Fantastic software, and they have numerous posts detailing their exact encryption techniques. Remember one really good password, and the rest of your passwords can all be completely random. You can sync it over wifi or Dropbox. I don't know the passwords to just about any websites now thanks to 1Password. We mandate it at our company now too. If you can tell me the password to "Important Website X" off the top of your head, you're doing it wrong.

<BTW: This goes without saying, but I'll say it anyway: Don't lose your 1 master password or your password database. ;) >
