What is ID?

Four pillars of a real identity platform.

Not a login button. A complete identity layer — issuance, authentication, consent, and tiered trust.

🪪

UCID

A permanent, verifiable identifier — not an email, not a username. One identity that follows you across every connected service.

🔑

Passkey

No passwords. Ever. Your device biometrics are the key. Phishing-resistant authentication backed by the secure enclave.

🛡

Consent API

Every data request requires explicit user consent. You control what's shared — scope by scope, service by service.

📊

Verification

Six tiers from registered to institutional — services request the minimum level they need, and nothing more.

The verification journey

From registered to institutional.

Each tier unlocks higher-trust interactions. Identity-verified tiers (ID3+) carry a profile photo on the card.

ID0
Unverified

A pending application. No credential issued yet.

ID1
Registered

Passkey registered and email confirmed. Unlocks login, profile, and basic claims.

ID2
Verified

Profile and address reviewed. Unlocks verified-age (boolean) checks.

ID3
Identity Verified

Government document and photo reviewed. Unlocks the protected profile photo claim.

ID4
Trusted

In-person or official document check. High-assurance interactions.

ID5
Institutional

Highest assurance. Reserved for institutional-grade identity.

The platform

This is your identity wallet.

Your dashboard is the home of your digital identity. See your card, track verification progress, manage the passkeys on your devices, and review every connected app — all in one place.

Everything is yours to control. Revoke a device or an app's access at any time.

For developers

Standard OAuth 2.0 — ready in minutes.

Add ID authentication to any service with PKCE-secured OAuth 2.0 and an OIDC-compatible userinfo endpoint. Request only the scopes you need — your users consent to each one individually.

Developer portal Read the docs
🔐

OAuth 2.0 + PKCE

Standard authorization code flow with PKCE. Works with any language or framework.

🪪

OIDC userinfo

Standard /userinfo endpoint. Scopes include ucid, verified_age, verification_level.

Consent-scoped

Every data request requires user consent — scopes are shown in plain language before approval.

Connected services

ID is built to connect.

Services integrate by requesting only the scopes they need. Three common integration patterns:

🔓

Login only

Identify the user with openid + ucid. No personal data beyond a stable identifier.

🔞

Age verification

Request verified_age — the response is a boolean. The birthdate is never disclosed.

Identity verification

Request verification_level to confirm assurance tier (ID0–ID5) for high-trust flows.

FAQ

Common questions.

Everything you need to know before applying for your UCID.

What is a UCID?

A UCID (Universal Credential ID) is a permanent, human-readable identifier — something like LEON 0001. Unlike an email address, it never changes and is not tied to any provider. It's the stable anchor for your identity across every service that accepts ID.

How do I sign in? Do I need a password?

No passwords, ever. ID uses passkeys — your device's built-in biometric sensor (Face ID, Touch ID, Windows Hello) authenticates you. The private key never leaves your device. It's phishing-resistant by design.

What verification level do I need?

Most services only require ID1 (account created) or ID2 (address verified). ID3 unlocks identity-verified features like a profile photo on your card. Services tell you upfront which minimum level they require — you're never surprised.

What happens to my documents after ID3 verification?

Your government document and selfie are encrypted before being stored and are only accessed by the ID review team for the purpose of verification. After the review is complete, they are not re-used or shared with third parties.

What data does an app actually see when I sign in?

Only what you explicitly approve. An app that requests verified_age receives a boolean (true/false) — not your birthdate. One that requests ucid gets your identifier — not your name or address. You see every scope in plain language before approving, and you can revoke access at any time from your dashboard.

Can I use my ID on multiple devices?

Yes. You can register a passkey on each device you use. From your dashboard, you can see every registered device and remove any you no longer use.

How long does it take to get an ID?

Minutes. Verify your email with a one-time code and you're through to a setup link right away — no manual review, no waiting. Follow it to register your passkey and reach ID01 instantly.

Is there a cost?

No. ID is free for individual users. Developers building integrations can register apps at no cost through the developer portal.
