A payment server for authenticating digital transactions, comprising:

• at least one processor;
• and
• a memory communicatively coupled to the at least one processor, wherein the memory stores processor instructions which, upon execution, causes the at least one processor to:
• receive a device registration request and a device attestation response including a first token from a device, wherein the first token is sent by a first server to a second server, and wherein, in response to receiving the first token from the first server, the second server sends device information to the first server;
• in response to the device registration request, provide a device registration response to the device, wherein the device registration response is stored on the device;
• receive, from the device, a first payment transaction request and an enrollment request to authenticate a second payment transaction request using a first type of authentication technique;
• and
• enroll the device to the first type of authentication technique and provide 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.
