OAuth

Sketch: you keep your master key while a helper waits; then a checklist on the real service gives the app a limited valet key.

OAuth is an open standard that lets an app use your account on another service with your permission, without getting your password.

Think of it like this: OAuth is a valet key: the valet can park the car but can’t open the trunk, and you can take the key back. Your password, the master key, stays with you.
