Upgrade from Convenience to Confidence

Passkeys+ brings cryptographic strength and device control to every use case, from login to payment.
Protect your users across all critical flows, not just the sign-in screen.

Authentication

The familiar use case - done better.
‍
Passkeys+ supports standard passkey authentication with stronger guarantees: device verification, attestation, and support for flexible user journeys. You get all the benefits of passkeys, plus control over how and where they're used.

Transaction Signing

Prove that a user made a transaction. Cryptographically.

Whether you're a bank, wallet, or marketplace, Passkeys+ can cryptographically sign transactions with attestation and device binding, giving you hard proof tied to a verified device, not just a session.

3DS Challenge Flow

Seamless payments with cryptographic proof of user presence.

Passkeys+ integrates directly into the 3DS challenge flow. We verify that the challenge response comes from a known device,  streamlining step-up authentication and reducing false declines without compromising on security.

Better Together

ZSM Completes the Passkey Equation

Passkeys offer convenience, but ZSM provides the missing control, visibility, and cryptographic strength needed for high-assurance use cases.
