OAuth
termweb devsecurityprivacy
Stands for: OAuth 2.0
A standard that lets an app access your data on another service without handling your password.
OAuth 2.0 is the "Log in with..." and "allow this app to..." flow: you authorize limited, revocable access, and the app receives a token rather than your credentials. OpenID Connect builds identity on top of it. Done right, it means one breach does not hand over your password everywhere.
Also known as: oauth, oauth2, oidc, openid connect, authorization code
