I made the simplest Rust server I could to learn the basic workflow of OAuth2, it gets the user gmail after you log in with Google. I also included some instructions of how to set up the Google account. Feel free to check it out! https://github.com/alexgf0/oauth

While learning how OAuth works I developed this project to exemplify the simplest way avoiding OAuth libraries.

Feedback is very much welcome!

OAuth2 is very different from the original OAuth.

Yeah, you're right. I changed the github documentation to showcase that I'm actually using OAuth2. Thanks!
