Newbie here. I am having a difficult time understanding all the logins required for various Canvas resources. For example, I just tried to enroll in an Admin course found on the Canvas Resources page here The specified item was not found. but this course itself Canvas Admin Orientation wanted to know if I already have a "Community Resources Login". I have no idea which set of credentials they are asking for, or if I need to create another set for this system.
So I keep running into Canvas instances (like the course above on "resources.instructure.com") that require a login. Some systems seem to be connected to others, some not. Could someone please explain how all these systems are connected? I already have several sets of credentials and it is getting confusing. Thanks.
