There have been a few issues with a 10 character minimum in the past. I've received complaints from people that they could not create an account because they did not realize that the password needs to be at least 10 characters (when 8 is much more common). Ideally, we would improve the UI so that the password character minimum is more clear, but this is a quick fix to solve the issue so that GM runs more smoothly.
