OAuth
also OAuth 2.0
An authorization standard that lets an app access your account on another service via tokens, without sharing your password.
Analogy
Like a hotel keycard that opens specific doors without giving out the master key.
Why it matters
Most app connections in Zapier, Make, and n8n use OAuth, so understanding token scopes and refresh helps you fix broken connections.
In practice
Connecting your Google account to Make via an OAuth consent screen instead of a password.
