Systems and methods for remote authentication using Single Sign-On (SSO) credentials are disclosed. An implementation includes transmitting a request for an identification code from an application to a wireless service provider, the request provided through an encrypted transport protocol, receiving the identification code as a messaging service message from the wireless service provider, securely routing the received identification code to the requesting application, upon receipt of the identification code at the application, retrieving an authentication token for the application through the encrypted transport protocol and providing the authentication token to an application content server to allow content transfer between the application content server and the application.
