Hello,
Thank you for approaching us.
The first user that logged in is the domain owner.
You can identify the domain owner by below things :
- The domain owner has some by default permissions like if a user creates an account or project, the domain owner is by default present in the Account or Project(the user need not invite the domain owner explicitly).
- Also, the domain owner has some additional Settings panel which is only limited to him and is not viewed by other users. Please refer below link:
If you still have any issues, Kindly feel free to contact us. We are happy to help you.
Thanks,
