Each StatusPage account has only one Account Owner. There can be multiple team members within an account.
The difference between these two types of users is the Account Owner can delete Team Members and assign account ownership to others. That's it. Both users can manage and access everything within the status page aside from this one difference.
Only the existing Account Owner has permissions to grant someone else Account Ownership.
An account can have multiple pages. Each page has it's own subscription and cost. See adding additional pages.
All team members and the account owner have access to all of the pages within the account.
