Just to add - if this is about Internet forms and the mess of different standards for passwords and UserId's - switch to Firfox. You will never go back and you won't need a password tool like RoboForm (which I agree is one of the better ones)
FireFox has it built in and it is intelligent and customizable. Best of all whenever you go to that page/site it remembers and puts both UserID and password in the fields -0 no need to click another button it just remembers it

Might not want this for a portable in case you loose it...?
