I stumbled upon a video about this yesterday.

One thing that has worked for me is to slowly type random keys while randomly hitting the shift key. This seems to work better for me than using a random password generator. I think it is because I remember the pattern of the keys that my fingers are pressing. One problem I have is remembering which place the password is used for. I usually have to try a couple of different ones to get it right--say if I don't go to that website that often. --- Sorry My English

Sounds awesome, but I just can't imagine this being better than playing with a keyboard and a mouse(optional).

who would trust phones nowadays anyways?

boom goes the dynamite.
