Authenticating user requests via interactionless authentication

Abstract

Methods and systems for reducing network traffic associated with authenticating user requests via interactionless authentication are disclosed. For example, in connection with a user device transmitting a user request to access a resource, the system determines a first address associated with the user device. The system then transmits the first address to a third-party authentication platform that determines a Uniform Resource Locator (URL) that is specific to a mobile carrier. The system then transmits a verification token request associated with the mobile carrier. The system receives a verification token from the URL, and transmits an authentication request to the third-party authentication platform comprising the verification token. The system then receives, from the third-party authentication platform, an authentication response comprising a user device identifier. In response to receiving the authentication response, the system performs an authentication action associated with the user request.
