In this version, users may no longer set their password to be the same as their username. Users affected by this will be forced to change their password on their first login. Additionally, a tool has been added to the Admin Control Panel to reset these users’ passwords.
I hate having to do that for work. So when I’m forced to change one, I go through and change the rest of them at the same time so I only have to remember 1 instead of 4 different ones.
