LastPass seems like a pretty good solution for password storage and management

Cross browser, cross platform, cloud-based... could be good. Storing all my passwords on a server I don\'t control makes me nervous, but I'll just have to check it out.

UPDATE:
They claim to en/decrypt locally, and transmit/store the encrypted blob only. I've been using LastPass now for a while and am totally in love!
