A source device for systems and methods of verifying an authentication based on dynamic scoring is disclosed, wherein the source device is configured to receive at least one identification feature from a user, and to communicate the identification feature to a verification unit. The verification unit is configured to generate a base verification score associated with the user based on at least one identification input, the identification input comprising the identification feature, a feature validity rating, and a source device validity rating, to receive a request to access a service, wherein the verification unit compares the base verification score with a service authorization threshold associated with the service, and to grant access to the service when the base verification score meets the service authorization threshold.
