Now, if you are like me, already have a huge database of password stored in your KeePass (or KeePassX), you won’t want to enter individually to LastPass. You just have to visit the site and it will auto-login for you.
LastPass is an online password manager that works in (almost) all browsers. One thing that it doesn’t support is a browser plugin that can detect the site you are visiting and auto-fill the login field for you. It works in all platforms, including portable USB drive and can generate secure passwords and store them securely.
KeePass ( KeepassX for Linux) has always been my favorite password manager.
