LastPass is an online password manager that automatically fills in saved logins and forms with the click of a button. This handy little Web freeware and browser plug-in also syncs your data to any computer you use regularly. With LastPass you won't need to remember passwords anymore. You can easily log into your websites with a single click of your mouse. You can set up multiple 'profiles' and automatically fill your personal information into web forms accurately and safely. It protects against identity theft by keeping sensitive data encrypted on your PC. Your LastPass vault isn't limited to only securely storing usernames and passwords, any confidential text data can be placed in your vault for safe keeping.
