This form is only for requesting a guest account for an external user that MUST have access to Canvas, and can only be filled out by UT employees. Guests can't request an account for themselves. For other guest accounts use the LISA service portal https://selfservice.utwente.nl choose "Order Services", "Authorization" and "Guest Account (X-account)".
Before requesting a guest account search the UT people pages to check if the person you want to request Canvas access for is already known at the University. People listed on the People pages already have Canvas access.
