What's the alternative? Generate randomized passwords and memorize them all? I have 250+ passwords for different websites, and not a great deal of choice about it. This is certainly way better than the actual likely alternative -- using the same password on all 250+ sites.

1Password's browser extension v4, in contrast, fills in the form only when you press a key combination (⌘-\ on OSX), and has you enter your master password into a dropdown from the OSX Menu Bar, and not inside the browser frame. Pretty snazzy all around.

Aha, I see the distinction now. Thanks. Enough to simply disable autofill in LastPass then? I'm loathe to learn a new system because of such a seemingly small size vulnerability.

LastPass has me enter the master password in a pop up window when I click on the icon from the extension (firefox/chrome), although I suppose that's maybe not as good as an independent application?

Exactly.

I can, not only disable autofill in the Lastpass configuration, but also set to require password reprompt for any of my credentials. I could also individually disable autofill for any credential.

Please should first know how something works before criticizing.

Just because there's no autofill doesn't mean you don't have a password manager.

In 1Password 4, there is no auto-filling. People can use Ctrl-\ or Cmd-\ to tell 1Password to "fill this page". In versions prior to 4, auto-fill was an option. (I'm not sure which versions had what defaults.)

Oh I know. I use 1Password. I forgot to mention that your solution works better but I believe blazingice mentioned it above.
