LastPass for Chrome
LastPass is a free online password manager and Form Filler that not only helps you track the zillions of passwords for social networks and other Web sites, but helps make them more secure. This extension allows you to import from every major password storage vendor (such as Roboform, KeePass, PasswordSafe, MyPasswordSafe, Sxipper, TurboPasswords, PassPack, Firefox and IE's built in password manager) and export too. It captures passwords that some others don't like for AJAX forms. Sensitive data is encrypted locally before it is uploaded so anyone sniffing around can't get access. One-time passwords and a screen keyboard also help protect your password list.
