I personally use unique 65-100char passwords, so data breaches cannot touch me any more. Also a possiblity of keylogger is possible as well, or some kind of data leak.
you would be the luckiest person in the world to get 8 alphanumerics done in 12 rights.
You need help dude
100 char password, wow...That is more then 512 bits of data. Servers don't even use hashes larger that 512 bits.
It would be more profitable for someone to just try to get a collision, then to actually guess a password.
Especially since they are unique, they would have no use of the password, just a random number that gives that hash.
