Identity,
signed for what's next.
Quant0 is an identity infrastructure platform built for modern applications and enterprises - combining authentication, authorization and quantum-safe cryptography in one platform.
Identity is becoming
a security boundary.
Applications increasingly depend on identity for every request, transaction and interaction. Quant0 puts that identity layer behind a security architecture designed for today - and for the cryptographic challenges ahead.
Prepare your identity
layer before you need to.
Quant0 uses hybrid cryptographic signatures that combine established classical cryptography with post-quantum algorithms. Applications can use familiar identity protocols today while preparing for a post-quantum future.

Post-quantum signature
One identity layer.
Every capability you need.
From your first authenticated request to enterprise federation, provisioning and audit - Quant0 provides the identity infrastructure behind your applications.
Identity
Organizations, users, groups, memberships and tenant-aware identity.
password-authentication
Modern auth flows with MFA, session controls and hybrid token signing.
SCIM
Automated provisioning and group synchronization to connected apps.
Billing
Plans, subscriptions, invoices, payment methods and gateways.
Audit
Immutable audit logs, security events and compliance monitoring.
Webhooks
Reliable outbound events with retry, signing and DLQ handling.
Identity without
infrastructure debt.
Quant0 separates the public API edge from identity, token, authorization, billing, audit and provisioning services. The result is a platform designed around explicit contracts and independent services.
Security is not
an add-on.
Quant0 builds security into the identity lifecycle - from token issuance and authorization to audit trails and service-to-service communication.
Build identity
into your application.
Start with APIs and integrations that let your team focus on your product instead of rebuilding identity infrastructure.
const quant0 = new Quant0({
domain: "auth.quant0.io",
});
const session =
await quant0.authenticate({
provider: "oidc",
});
console.log(session.user);Everything you need
to build with Quant0.
