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 credential card

Proof of Human

Highest-assurance uniqueness signal from Orb verification. Best for one-person-one-action flows and strong Sybil resistance.

Proof of Attributes credential card

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 credential card

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.
