yes, the keychain is cool. but i use many browsers. including ones (firefox) naming no names that don't support it. i don't want to have to keep remembering all my passwords in every different browser. enter 1passwd.
cool little util that has a plugin for all of the major browsers. it can access all your passwords in all your browsers. it can fill in forms for you automatically too. it will even make you a nice cup of coffee in the morning for you too (probably not)
share and enjoy
