It's a great online password manager I've been using a lot - check it out at http://www.clipperz.com/
They got everything I need - locally encrypted database, one-time passes to login without risk of compromising your master password, offline backups (fully encrypted). Their "Zero-knowledge web applications" concept is of particular interest.
The service is free, they're running off donations, so I talked them into accepting bitcoin as well - here is the donations page, listing the address: http://www.clipperz.com/donations
I'm not affiliated with them, just a satisfied user.
