Verify once.
Authorize everything.
Proof is the identity network behind the internet's most important transactions.
Built for the moments that can’t go wrong
From the documents you sign to the agents acting on your behalf — every action is tied to a verified identity, sealed at the moment it happens.
Everything you sign
Signatures and notarizations bound to a verified signer, then sealed so they can't be repudiated.
Everything you do online
Account openings, payments, and logins tied to a real human — not a stolen or synthetic credential.
Everything an agent does for you
Every action an AI agent takes on your behalf is authorized and traceable straight back to you.
A digital identity accepted everywhere
Millions of verified users secure an authorization through our network every year. It’s one of the only digital identities that is trusted by every industry from real estate, financial services, healthcare and public service. Verify your identity once and then be instantly trusted by any business in our network.
Cryptographically secure your identity to anything
The solution to forgery and impersonation is to cryptographically sign all documents and data with your legal digital identity. It’s the same technological leap that eliminated counterfeit credit cards in the payment industry, but can now secure everything you sign, authorize, create or agree to.
Every authorization is now verifiable
Every transaction produces a record, whether it’s a document, content, data or media. This is evidence should there be a dispute. With verifiable records, organizations can immediately trust the authenticity of any evidence they receive, without requiring users to present their identification every time.
