Rated 5 out of 5 stars
First aspect of this extension is that it adds an extra security level between you and the potential account hijackers you are afraid of.
Secondly, it encrypts and stores all your passwords in a safe cloud and whenever you log in to last pass with your master password, it relieves you of duty to remember all of them.
Thirdly, it lets you skip the annoying process of filling your name and password. It automatically fills the empty parts or just auto-logins to every website that usually don't according to what you desire unless they are ultra secure like university account websites. Remember though, that the third option endangers your security if you share your system with someone else and may be interested in additional security options lastpass presents.
