About
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.
OpenAPI is a specification language for defining HTTP APIs, typically written in 
YAML or 
JSON.
It enables automated generation of interactive documentation (via tools such as 
Swagger UI and Redoc), schema-based request and response validation, automatic creation of client SDKs and server stubs in multiple programming languages, and integration into CI/CD pipelines.
