LastPass brings secure password management to Safari on Mac
Those of you running Snow Leopard, you'll need to run Safari in 32-bit mode - the LastPass installer will notify you when you launch it.
The LastPass plugin supports importing from 1Password, and their iPhone app is currently available on the App Store [iTunes link]. It's a great way to securely manage your passwords on Windows, Linux, and Mac - and in an ever-increasing number of browsers.
Google Chrome users, sit tight - a .crx extension can't be too far away now.
