To remove or invite new users to your Archera account go to the user section of the settings page:
Then you can click the remove button to revoke access or change the user's role in the "Archera Organization Members" table.
To add users click the "Invite Members" button at the bottom of the page to invite a new user via their email & with a specific role.
If you would like to opt-out of giving your cloud account representatives or MSP/Reseller/Cloud-Consultants access to your environment you can restrict their role or remove them from your account entirely via this page as well.
