OAuth 2.0
PronunciationOH-awth too-point-oh
Definition
A standard that lets a user give an app limited access to their account on another service, without sharing their password. It powers "Sign in with Google".
Where you hear it
Social login and third-party integrations.
Examples
We added Google login using OAuth 2.0.
The app asks for permission to read your calendar only.
Common mistake
Calling OAuth an authentication protocol. It is for authorization; OpenID Connect adds identity on top.
