In some implementations, a computing system can manage access to media sources associated with a user's media account. For example, the system can coordinate access to a user's media account between local and network devices such that when access to the user's media account is granted to an application on a user device, the application can access both local and network media sources associated with the user's media account. Similarly, when access to the user's media account is revoked from an application at a user device or at a network device, the application is prevented from accessing both local and network media sources associated with the user's media account.
