A system provides a way for a person to control access to digital assets, including financial accounts, through a common gateway that can interact on the person's behalf with service providers that manage the digital assets. Brokers may act as intermediaries between the gateway and the service providers, providing a common interface to the gateway and a specific interface to a service provider. Trigger events can cause the gateway to interact with the service providers, causing the service providers to take a desired action. The trigger events may include notification sent by the person, timed events, and other detected events.
