Unpairing a pairing code

[scotty702]

I have a problem with Canvas. I had a parent who wanted a pairing code. I did it wrong, and now the parent is actually observing me as a teacher, not their child's account. How do I undo this?

I am a controller - this comes from one of my teachers.  Is there any way to reset this , or generate a new code so the parent is not observing the teacher?

Thank you
