In this guide, you will set up a hardened, fully functional OAuth 2.0 (OAuth2) server. It will take you about ~15 minutes. This guide is for you, if you are looking to do something like in the gif on the right, or more specifically:

• You want to use OAuth2 for API security.
• You want to open up your API to third party developers like Dropbox, or GitHub.
• You want to become and identity provider like Google, Facebook, or Twitter.
• You need to federate (delegate) authentication or authorization.

We will use ORY Hydra (open source), a security-first OAuth2 and OpenID Connect server written in Golang.
