I hate it that each website has different rules and that most of the time they don't tell you them all. Like they don't tell you what are illegal characters. Sometimes the error messages are inscrutable. They each seem to have different length constraints. I hate it when they have a length limitation. One site I went to had a maximum length but just truncated my password without telling me, but worse was that when it truncated my password, it wouldn't accept my original full password. I had to keep deleting characters off the end until it worked.
