Extremely useful. Rated 5 out of 5 stars

Once adopted, it's for the rest of your life. Lastpass saves me big amount of time every day. I no longer hesitate switching web sites or computer, as logging in and out is no longer the pain it used to be. Add bookmarklets on your iphone, and browsing the web from a mobile device becomes at last a reality. Definitely a must have. Kudos to the developers.
