That's what I'm thinking also. I don't understand how a computer can know if a password is partially correct. If that were true, a brute force attack on the following password could be cracked rather easily on the weakest of computers:
&*&*(89234897sdlkjehruipIIOPUE3R-708760340=-23-0-0978s-89234^&^234897^&^7@3
In other words, the computer would be able to know the correct first character and then move on to the next, etc. I'm almost certain it is NOT possible to crack a password this way.
By the way, again, it's always possible to criticize anything that is not "long and random". It would be helpful to propose an improvement on a password recall system if you see a notable weakness. Not everybody can have their password vault program/notebook with them at all times.
