Systems and techniques for an adaptive authentication system are described herein. In an example, an adaptive authentication system is adapted to receive a request at a first entity from a second entity for secure data of a user, where the second entity is remote from the first entity. The adaptive authentication system may be further adapted to transmit a prompt to a user device associated with the user for authentication of the user and authentication of the request. The adaptive authentication system may be further adapted to receive a response to the prompt and authenticate the user and the request based on the response. The adaptive authentication system may be further adapted to transmit the secure data of the user to the second entity.
