I’ve been using 1Password for almost a year now and I love it. 1Password Mini (that thing that lives in the OS X menu bar) is my favorite, especially combined with the Cmd+Alt+\ (or ⌘⌥\) shortcut key that opens the menu, focused on Search. Type a few letters, hit the right arrow, hit the down arrow, hit Enter and boom — you have your password in your clipboard for 90 seconds. Amazing...
