Abstract: An authentication system is implemented for authenticating the identity of an entity. By registering and verifying user accounts for entities using the authentication system, the authentication system ensures with high confidence that user accounts are associated with verified entities. Authenticating identities between entities may be established and represented in the authentication system by authenticated identity objects. The entities may access the authenticated identity objects by requesting dynamic tokens linked to the authenticated identity object. A requesting entity can provide the dynamic token to another entity who may then provide the dynamic token back to the authentication system. Based on verifying the dynamic token, the authentication system provides an indication of a verification of the entity. In this way, an entity may rely on the verification prior to further interacting with another entity or individual.
