API Development with OAuth2 Guide

Hello everyone,

I've just started developing an API for a social media project, that are going to be used on mobile. When I searched through Authentication methods I saw OAuth2 will be sufficient for now and decided to use Laravel/Passport. I followed the guide and set up my OAuth2 but I still didn't get the workflow. Is there any videos? I watch Incremental APIs and Laravel Passport videos but they don't match since Incremental APIs videos are for an older version.

Thanks in advance
