I knew that students would be forgetting their passwords (already more than 10 have come to me asking me what their passwords were) so rather than making a password retrieval/changing system, I made the executive decision that it didn't particularly matter on a system I made the morning before a class that has no impact on grades or anything else. The system is purely for the students' convenience at testing code. The only reason there are usernames/passwords to begin with is so students can view all of their past submissions to the system.
