Used Whisper for many years but switched to KeePass earlier this year and like it. The availability of a conversion tool for my several hundred passwords was a key factor in the choice. I did briefly try Roboform in between, but I must be a klutz because I could not get it to work the way it should. Anyway, sounding a little like sour grapes, I'm somewhat wary of apps that automatically fill in login info, even if it is done securely. I don't find the extra effort of opening KeePass and doing Ctrl-B, Ctrl-C for the login and password a chore.

Has anyone mentioned Siren - http://www.scarabee-software.net/en/siren.html
