Abstract: A virtual application container can manage a plurality of secondary applications using a graphical user interface (GUI). The secondary applications may be selectively downloadable by a user and/or provided by third-party external providers. The application execution container may include a common feature or services interface that is used by the secondary applications that are executed in the GUI, which may include user verification and/or authentication information. The application execution container may include security and control functions that may be used by external service providers to ensure that users are properly authenticated, and the ability to add and/or utilize individual secondary applications may be granted based on predetermined eligibility criteria.
