If you are a student who teaches the login screen, there are three scenarios to consider.
- You do not know your WeBWorK username. Or you think you know it, but you are wrong.
- You do not know your WeBWorK password. Or you think you know it, but you are wrong.
- You correctly know both.
The first two situations are common when a student had their account created with LTI.
Only the third situation is something where it makes sense and is security-wise to acknowledge the person is a student and actively redirect to the LMS.
