World ID
A more human internet with global proof of personhood. Privacy‑First. Self‑custodial. Decentralized.


World ID is a digital passport that lets you prove you are a unique and real person while remaining anonymous.
Use "Sign in with Worldcoin" to authenticate into web, mobile, and decentralized applications, and privately share your personhood verifications including phone number for ease, or biometrics for the maximum level of assurance.
Build with World ID SDK
The protocol is live and open source. The Worldcoin community is building a more human economic system, and developers can start building here.
