HMAC API Authentication
& ExtraAuth: Securing Your APIs

ExtraAuth is the Only Solution for ZeroTrust HMAC & Two-Factor Authentication for APIs

ExtraAuth is a comprehensive solution for securing API to API authentication with HMAC. With the increasing need for robust security measures, ExtraAuth provides an additional layer of protection to ensure secure and reliable communication between APIs.

How HMAC API Authentication Works
HMAC (Hash-based Message Authentication Code) API authentication is a cryptographic mechanism used to verify the integrity and authenticity of API requests. Here's a high-level overview of how it works:
​
  • The client and server establish a shared secret key known only to them.</li>   
  • The client constructs an API request message, which typically includes the request method, URL, headers, and payload.   
  • Using a hashing algorithm (such as SHA-256 or SHA-512), the client combines the request message with the shared secret key to generate an HMAC, which is a unique hash code.   
  • The client includes the HMAC as an authentication token in the API request, typically in the request headers.   
  • On the server side, the server reconstructs the HMAC using the received request message and the same hashing algorithm.   
  • The server compares the computed HMAC with the received HMAC to authenticate and verify the integrity of the request.

Unlock the Power of ExtraAuth with HMAC 
API Authentication

ExtraAuth simplifies and fortifies the API authentication process with its advanced features and functionalities.
Here's how it works:
STEP 01

Client Requests HMAC Code

The client initiates the authentication process by requesting HMAC from ExtraAuth.

STEP 03

Client Includes TOTP Code in API Request

The client includes the HMAC in the API request header to authenticate itself.

STEP 02

ExtraAuth Generates HMAC

ExtraAuth generates a unique HMAC based on the client's request.

STEP 04

Server Validates HMAC with ExtraAuth

The server verifies the HMAC with ExtraAuth to authenticate the client and authorize the API to API communication.
