Passwords do NOT support "#"
I've had a problem changing my password and login in for many years. After a ton of testing, i figured out that the "#" i use in pretty much all of my passwords(hey don't hack me!) doesn't work ! If i make a reset password to one with "#" and then try to login, i CANNOT.

This is immediately resolved once i remove the "#". My password includes lower and upper case as well as numbers along the "#". I believe other symbols of the type "#" belongs to may also be affected, or it may simply be an anomaly.
