Probably the silliest thing I have run into was some game. It asked you to set two passwords. You needed both to login. The second password couldn’t be changed. This is why it was secure, see. (…What.)

When I created my account and set the second password, I couldn’t log on the second time. Because I had entered a 20 character second password. It was accepted and verified during the account creation just fine. On the second login, it only accepted 16 characters. (It let you enter 20 characters but said it was too long.) Trying to enter first 16 characters of the second password didn’t work, of course.

I then contacted the support, and they did manage to reset the second password anyway. (What is this even)
