On any system there are tools I feel I always need, Lasspass is one of those tools.

Using computers means using security and that means passwords. And good passwords are about impossible to remember, so, Lastpass. Make one GOOD password you will remember and Lasspass will help you make good ones for all the sites you visit and it will remember them. Even better once it has your login information and you have logged into it visiting a site will just mean opening the site and hitting Login, the information will already be in their fields.
