Admins have full access to their Teamstack organization including billing and subscription information. Only Admins are able to create other Admin users. 

Managers have the ability to manage users, groups, applications and security in their Teamstack organization. They don’t have access to change organization settings. 

Users only have the ability to manage their own resources and edit their user profile. They have the ability to add multiple emails to the user profile, which allows users to log in with every email address associated with the user profile. However, the system emails will only be sent to the “primary” email address.
