nforwardauth is a lightweight and straightforward reverse proxy authentication service designed to enhance access control for other web applications, particularly those hosted on a server without built-in authentication mechanisms. By intercepting incoming requests to specific URLs, nforwardauth authenticates users against an external OpenID Connect provider, such as Google or GitHub, allowing seamless single sign-on (SSO) functionality. This tool is particularly useful for users managing self-hosted applications who want to add a layer of security without integrating complex authentication systems directly into each application.
The project is open source and aims to simplify the process of implementing authentication for applications running in Docker or other environments, allowing developers to enforce access policies effectively. nforwardauth can be easily configured to work with various web applications, providing a versatile solution that fosters better security practices while maintaining user convenience. Its minimal footprint and ease of deployment make it an attractive choice for self-hosting enthusiasts looking to bolster their security effortlessly.
