Identity Vault Service

Concepts and technologies are disclosed for an identity vault service. According to one aspect disclosed herein, an identity vault service system can collect self-attested and operator-attested user information. The operator-attested user information can be associated with a user and a mobile telecommunications service provided to the user by a mobile network operator. The system can create a trusted digital identity of the user based upon the self-attested and operator-attested user information. The system can receive an identity access request from a third party. The request can be for access to at least a portion of the trusted digital identity for use by the third party in performance of an act. The system can send a consent request to a user device and can receive a consent response that indicates whether the user permits access to at least the portion of the trusted digital identity of the user.
