You can set up an unlimited number of users in your ASQ Online account. And, each of those users can be assigned as an Account Admin, Program Admin, and/or Provider for all programs within your online account. A user who has Reviewer access in a program, can only have Reviewer access within that program as the Reviewer has no access to child profile data.
There is no limit to the number of Account Administrators, Program Administrators, Providers, and Reviewers that you can assign.
You can also assign multiple roles to a single user. Users that have multiple roles can toggle between those roles using the dropdown menu at the top of the ASQ Online webpage.
