What is NGINX reverse proxy authentication passthrough?

An authentication passthrough setup when using Nginx as a reverse proxy involves Nginx not authenticating the client itself but instead sending the authentication request directly to the backend server. To put it another way, Nginx serves as a transparent middleman, transmitting the client’s authentication credentials to the backend server for verification.

Advantages are as follows:

• • Simple configuration
  • Compatibility with existing authentication systems
  • Centralized authentication
  • Flexibility in authentication methods

How does the authentication passthrough works?

1. Through Nginx, the client (such as a web browser) submits a request to access a protected resource.

2. The request is obtained by Nginx, who then sends it to the backend server to handle the authentication procedure.

3. By comparing the client’s credentials, such as username and password, to a user database or authentication service, the backend server (such as an application server or API server) carries out the authentication.

4. Following request authentication, the backend server replies to Nginx with information about whether the client is permitted access to the requested resource.

5. The backend server sends the response to Nginx, who then sends it back to the client. The response tells Nginx whether to provide the client access to the resource, and it then serves the appropriate content in response.
