Admin users are user which have been granted access to the Admin app. Non-admin users do not have access to the Admin app.
By default the first innius user in a company is an admin user, and from then on new users are non-admin users.
Other company users can become admin users when an existing admin
user grants them access. To do this open the People page in the Admin
app, by clicking the side menu open (1). and then opening the People page (2).
Here you will see the names of the users in your company, and their designated authorisation level (3). You can edit users, by clicking on the 3 dots button on the right of each user row (4).
The User page shows the details associated with each user, and allows these to be changed, except from their email address. You can open the authorisation field and select a different level of authorisation, such as Administrator (5).
Once you've made the change, you can click Save (6).
The user will now have access to the Admin app, in addition to the Operations and Insight apps.
