World ID
World ID is a privacy-preserving protocol that lets people prove they are real and unique online without sharing personal information. It gives developers a high-assurance trust layer to stop bots, duplicate accounts, and abuse — while keeping onboarding fast and user data off your servers. Through credentials like Proof of Human, Proof of Attributes, and Proof of Presence, World ID extends that trust layer with additional proofs without exposing underlying user data.Credentials
Proof of Human
Highest-assurance uniqueness signal from Orb verification. Best for one-person-one-action flows and strong Sybil resistance.
Proof of Attributes
Proves possession of a unique government document through NFC checks. Useful for proof of age and document-backed access flows.
Proof of Presence
Low-friction liveness and facial similarity checks from a selfie flow. Best for sign-up and bot defense where speed matters most.
