User passwords printed on paperwork at a dental office?

My dental office just printed my password (to their portal) on some checkout paperwork.

I asked on law stackexchange and it doesn’t sound like this is a HIPAA violation, but I am really curious if this violates other regulations or goes against known best practices, as it seems really bad security-wise.

It doesn’t feel right that they can even see my password.

Any thoughts / resources much appreciated.
