About Application Ownership and Management

Applications are managed by individuals and owned by accounts.

The application manager has administrative rights to control the application. Initially, the user who creates an application is its manager. However, this person can transfer management of the application at any time. Once you transfer management of the application to another user, that user has the ability to remove your application access. Only a manager (and anyone the manager has granted administrative or share rights) can add and remove users from an application's access list and control user permissions (roles).

One account owns the application. The Billing Account Administrator is the individual who controls the account. Usually, an application lives in the account where the manager created it, but a Billing Account Administrator can transfer application ownership to another account at any time. If you're an account administrator, you cannot view the contents of an application in your account unless that application's manager has explicitly granted you access to it. However, you can delete an application from the account. As a Billing Account Administrator, you don't control user access to applications (application managers do), but you can deny a user access to the entire account (and therefore any application within it), if necessary.

Tip: What happens if an application manager isn't available? Say a manager has left your company without notice. No one can log in as the manager, leaving the application without a leader. In this case, you can promote an existing user of the application to manager.
