What is zKYC?
zKYC lets users verify their identity once and share a small cryptographic proof instead of full documents.
Why it matters
Traditional KYC flows are repetitive, slow, and expose sensitive documents to every service the user interacts with. zKYC flips that model — verify once, and then prove attributes with cryptographic proofs that disclose only what is necessary.
Key benefits
- Privacy-first: personal data stays protected.
- Reusable proofs: one verification, many uses.
- Better conversions: faster onboarding for users.
Quick overview
- Verify once inside zkPass.
- zkPass issues a small cryptographic proof.
- Services verify the proof without seeing documents.
For developers
Integrate once with our SDKs and accept zk-proofs from users — no need to handle raw identity documents across your services.
For product teams
Reduce drop-offs by removing repeated KYC steps and offer users a privacy-focused verification flow that builds trust.
