OAuth Auth Server through Workers

The text discusses the implementation of an OAuth 2.0 Authentication server using Cloudflare Workers to simplify the process, reduce latency, and segregate service logic from the authentication layer. It outlines the steps of the OAuth workflow and provides a detailed walkthrough of the implementation, including setup, accepting page after callback, redirecting back to consumer, code to token exchange, giving the token to the consumer, and validating tokens for accessing resources. The author also mentions that a follow-up blog post will cover an OAuth consumer implementation.
