I guess, but I use a "Pass-Phrase" on my new MacBook Pro, and it is under 40 characters and I think it's a bear to remember and type in every time, and realistically it is very secure.
I can maybe see upping things to 60 characters, but beyond that its just silly in my humble opinion...
On a side note, could someone explain how the hashing thing works?
I know that felgall has consistently talked about how passwords get hashed to some fixed-length, and if that is so, then it makes me wonder...
Don't you end up with tons of collisions if you take any length password and change it to, say a 40-character hash?
In your case, Force Flow, your 150 character Password would have to get condensed down to a 40-character hash, as would a 100-character Password, and so on.
