Comment on My password is not accepted because it is too long
CaptainBasculin@lemmy.bascul.in 1 week agoThink of it from a random guess perspective. Guessing a number randomly generated between 0-16 is easier than guessing one between 0-8.
Now think that all passwords are stored in certain amount of bits, so let’s compare 4 and 8 bits.
Each bit has a chance to be either 0 or 1, so guessing a single bit’s possibility is 1/2.
Guessing the correct orientation of 4 different bits takes 1/2^4^ = 1/16 Guessing the correct orientation of 8 different bits takes 1/2^8^ = 1/256

At a certain point it doesn’t matter as the password is effectively unguessable.
One weakness with longer passwords is that if they are created by humans chances are it will be easier to guess the pattern. This is true for all human created passwords but I think the longer ones are worse since there is more space to create a easily guessable pattern.
