Years ago it used to be the case that Unix passwords were limited to 8 characters, or that if you made the password longer than 8 characters the extra wouldn\'t make any differe
I think around the time when actual passwords were moved from /etc/passwd to shadow, on Linux . I am guessing around 2000, Red Hat 6.x had long passwords IIRC. Around 2000 there were still a lot of old SUN, and they had password and username limits.
