So I am attempting to do an ER diagram over a login, with just login data, and the base data of the person loggin in, and the connection between login_ID and Basedata/Stamdata_ID. Is this correct, or how would you guys do it?

Anytime I see "password" in a database field I ask about that. The days of putting a clear user password in the database is over. Are they still teaching this bad idea?

To be fair, "password" could be the encrypted/hashed value. It is not necessarily in clear text. Although I suspect you are correct in your assumption.
