Overview

This site contains reference documentation and how-to guides for Spring Authorization Server.

Introducing Spring Authorization Server

Spring Authorization Server is a framework that provides implementations of the OAuth 2.1 and OpenID Connect 1.0 specifications and other related specifications. It is built on top of Spring Security to provide a secure, light-weight, and customizable foundation for building OpenID Connect 1.0 Identity Providers and OAuth2 Authorization Server products.

Use Cases

The following list provides some use cases for using Spring Authorization Server compared to using an open source or commercial OAuth2 or OpenID Connect 1.0 Provider product.

  • Provides full control of configuration and customization when advanced customization scenarios are required.

  • Preference for a light-weight authorization server compared to a commercial product that includes all the "bells and whistles".

  • Potential savings in software licensing and/or hosting costs.

  • Quick startup and ease of use during development using the familiar Spring programming model.
