In Cenedril you manage roles under Team on the Team Members tab. In the table, the per-row buttons switch a member’s role between Admin and Member. Only the current owner can transfer the Account Owner role, by promoting another person to owner and confirming the transfer in the confirmation dialog.
Change a member’s role
Open Team
In the sidebar open Team. The page starts on the Team Members tab and shows a table with name, email, role, and last login. Each row carries the available actions on the right.
Pick the member
Find the row of the person whose role you want to change. The Role column shows the current level: Account Owner, Admin, or Member. No actions appear on your own entry.
Switch the role
Click the role button in the row. For a member it reads Promote to Admin and grants admin rights. For an admin it reads Revoke Admin Rights and returns the person to Member. The new role is saved immediately and the table refreshes.
Result: the Role column shows the changed level, and the person now has the matching rights.
Transfer ownership
Promote the person to owner
In the row of the person you want, click Promote to Owner. This button appears only when you are the Account Owner and the row belongs to another person.
Confirm the transfer
The Confirm Transfer of Ownership dialog opens, warning that you will lose the owner role and give up billing responsibility. Check the named person and click Confirm. Cancel closes the dialog without any change.
Result: the selected person now holds the Account Owner role, your own account has been downgraded to Admin, and billing access sits with the new owner.
