That means user accounts! Youll want to give your users control over their own account, and youll want to make sure that only they can access it. This is called authentication . Authentication is the process of confirming someones identity by validating something they know (like a password), something they have (like an RSA key pair), or something about them (like biometrics).
OAuth 2.0 is an authorization protocol that allows users to grant apps limited access to their resources without sharing passwords or other sensitive information
