🆚 OAuth vs. OpenID

OAuth is an open standard authorization protocol that allows applications to obtain limited access to user accounts without sharing passwords across web, mobile, and desktop environments.

It uses token-based authorization with access and refresh tokens, lets users grant specific permissions to applications such as access to profile data or contacts, and is widely adopted by online service providers such as Google, Facebook, Microsoft, and GitHub.

OpenID is a decentralized authentication protocol based on OAuth 2.0 that enables applications to verify a user's identity through an external identity provider instead of managing credentials directly.

It adds an identity layer on top of OAuth by issuing ID tokens that confirm who the user is, supports single sign-on across multiple services, and allows retrieval of basic profile information.
