Abstract: A system and computer-implemented method for authenticating digital transactions. The method includes receiving a device registration request and a device attestation response including at least a device integrity status from a device. In response to the device registration request, the method includes providing a device registration response to the device, based on validation of the device integrity status. Further, the method includes receiving a first payment transaction request and an enrolment request from the device via an application to authenticate a second payment transaction request using a first type of authentication technique. Finally, the method includes enrolling the device to the first type of authentication technique and providing a second token to the device based on a result of the first payment transaction request, wherein the second token is used for authenticating the second payment transaction request.
