Account owners can give access to any other user on your PeopleGoal account. There's no limit to the number of Account owners you can have (and no extra charge for adding more owners). However, you are giving users access to your full User list and Account settings, so make sure your new Account owner is authorized to see this data.
If they're not, you can make someone a Workspace owner or an App owner without giving them full Account owner access. You'll set this up in your App Settings, and you can view our Permissions and Visibility article to learn how to do this.

When you set someone as an account owner, they are not automatically set as an app or a workspace owner. You'll need to go to the individual Workspace settings and App settings to give them owner access in your Permissions menu.
