Knowing the length makes is defined easier, maybe not easy but easier.


It saves 1/Nth of the total time taken to brute force an N character password compared to starting from length 1. So any password where this is a significant fraction is so short that the time saved isn't really relevant.

So yes, "easier", technically. But not in any meaningful way.


Unless you attack a group and want to know which target has an easier to brute force password.
