Great to see that graph over there. I will probably use this as an argument the next time someone tries to make a sign up feature.
The only problem I see with these weird requirements people added to passwords is that it probably has to do with forcing the user to make it non-obvious. If you let people just type anything in they will type their names or something like that. So if that’s the case the problem eventually comes down to EASE OF USE X FAILPROOFING THE USER
