OrbitKit uses Google authentication, which means each human user should log in with their own Google account. You can invite others to work on your Organization!
On the Settings page, invite them by email. They will receive an email with instructions for accepting your invitation.
You must pick a role for each user. There is one permanent role, ADMIN, which has full access to everything - including the ability to add/remove users. You may optionally create additional roles and assign them limited permissions:
If you would like additional permissions, please reach out to support.
