Lastpass is a multi-platform, browser-integrated password and secure note manager. It is available as a plugin for Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and Safari. There is also a LastPass Password Manager bookmarklet for other browsers.
Passwords in LastPass Password Manager are protected by a master password and are encrypted locally and are synchronized to any other browser. It also has a form filler that automates password entering and form filling (sensitive and non-sensitive data alike). It also supports password generation, site sharing ("send password to a friend") and site logging.
LastPass offers a premium subscription that includes iPhone, BlackBerry, Android, Windows Phone, Windows Mobile, WebOS and Symbian applications, enhanced support, multi-factor authentication and no advertisements.
