LastPass is the last password you’ll ever have to remember. Setup LastPass using your Windows/Mac/Linux machine once done you’ll have your login and password data on your PC and your iPhone/iPod Touch seamlessly synced via a Host Proof Hosting method which does not allow LastPass (or anyone else) access to your sensitive data. LastPass for the desktop (Windows, Mac, Linux) is free.
LastPass allows you to quickly login to your accounts via a built in browser (Safari integration is _NOT_ possible yet), edit your accounts, see and fill your form fill data, generate new passwords all seamlessly synced to your LastPass account.
After an initial login your data is available to you even when you’re offline.
