Systems and methods for network-based authentication for connected vehicle access

In some implementations, an authentication system may receive a user authentication request identifying a primary device. The authentication system may generate a challenge associated with a user profile mapped to the primary device. The authentication system may transmit a challenge message including the challenge. The authentication system may receive a challenge response including a response to the challenge, wherein the response to the challenge includes identification information regarding the user profile. The authentication system may determine a set of primary services associated with the user profile mapped to the primary device and a set of secondary services associated with a set of secondary devices. The authentication system may generate a set of security keys mapped to the set of primary services and the set of secondary services. The authentication system may provision the primary device and the set of secondary devices with the set of security keys.
