Q: How to obtain a temporary or guest ASURITE in order to give sharepoint access to partners outside of ASU?

A: Blackboard Access
If you want an ASURITE ID to be able to take a class in Blackboard, please do the following: 

• Contact someone in the ASU department that you are working with and ask them to submit an online Courtesy Affiliate Request form at forms.asu.edu to request an account for you.

If you are a department and need to sponsor someone that requires an ASURITE ID to access ASU resources, please do the following:

• Go to forms.asu.edu, Computer Account Requests, and fill out a Courtesy Affiliate Request form on behalf of the person who needs the account;You must give the full name, birth date, non ASU email address, and if possible the last 4 digits of the SSN so we can make sure they aren't already in our system.

• If you have Guest access make sure to switch to the Folder view (the List view is by default and you can't see the content in that setting)
