In Pulsar there are currently 4 user access levels. Superadmin, Admin, User and Reader.

If you need to edit user permissions within your org, you'll need to head over to the User Settings Page.

These users have the highest level of access, granting them rights to all functions and the privilege to manage the team sub-domain and users. At the time of on-boarding and depending on your subscription, your Account Manager may grant you super admin access to allow you to manage your team, users, and data usage.

These users can create new searches. They also have almost the same privileges as Super Admins, but they are not able to view privatised searches, which have been set up by other Admin users, nor are they able to manage or override a Super admin user. Admin users are not able to archive searches.
While Admins are able to create log ins for other admins, readers, and users they are not able to create Super Admins.

These users can modify current searches. They can also launch historic and real-time data. They cannot create new searches or add new users, nor can they view private searches set up by an Admin or Super Admin.

This is an observer type of role, therefore these users can only view searches made available to them and are unable to modify, delete or create searches.
