OAuth 2.0

Definition

OAuth 2.0 is an open authorization standard that allows applications to gain limited access to user accounts on other services. It is the basis for 'Sign in with Google' and API authorization.

OAuth 2.0 allows centralized authorization without sharing passwords. Security risk: OAuth misconfigurations are a common attack vector listed in the OWASP API Security Top 10.
