Lastpass is good at what it does, remembering passwords. However, once you install it, you'll find that many websites don't work properly. For example, reddit will cease to function at all until you remove your cookies and login using lastpass. Other sites will have the username and password fields on their login page completely removed by lastpass so you literally cannot login until you remove (or disable) lastpass. Needless to say, I do not want lastpass to prevent me from ever logging into websites again, so it has been removed and I'll find a competitor.
