Passwordless

Zero Trust Login. No Passwords, No Phishing.

id3 Passwordless replaces passwords with mutual out-of-band authentication. The user matches a one-time code on the login screen with the one pushed to their phone, approves with a biometric, and signs in in under three seconds — nothing to steal, nothing to phish.

Technology partner

id3 × DualAuth

id3 Passwordless is powered by the Zero-Trust authentication technology of our partner DualAuth. id3 Technologies and DualAuth have a strategic partnership to co-develop joint identity and authentication solutions — combining id3's biometrics with DualAuth's ITU-T X.1280 mutual out-of-band protocol.

How It Works

A reversed, mutual authentication flow — the user proves the system is genuine before approving, all in under three seconds.

01

Enter your email

No password field. The system recognizes the user's registered device and initiates the challenge.

02

A one-time code appears

A unique 6-digit code is generated on the genuine login screen for this session only.

03

Match & approve on your phone

The same code is pushed to the registered smartphone. The user checks it matches, then approves with a fingerprint, face or PIN.

04

Session created

A cryptographically verified session is established — without ever transmitting a password or reusable secret.

Built on the ITU-T X.1280 mutual out-of-band authentication standard. Because the user verifies the system before approving, phishing, pharming and man-in-the-middle attacks are defeated at the protocol level.

Why id3 Passwordless

Other passwordless methods reduce friction but leave gaps. Mutual authentication closes them.

vs. Passwords & OTP / SMS

Nothing secret is typed, stored or sent — so there is no password to breach and no one-time code to intercept and replay.

vs. FIDO / Passkeys

No per-device enrollment or device-bound credentials to manage. One registered phone secures logins across every device and browser.

vs. Push authenticator apps

Plain push prompts can be approved blindly ("MFA fatigue"). Here the user must match a code, verifying the request is genuine before approving.

vs. PKI certificates

No private keys stored on endpoints to be stolen or copied. The cryptographic approval is bound to the session and the registered device.

Key Features

A Zero Trust login that is both stronger and faster than a password.

Mutual authentication (X.1280)

The user verifies the system and the system verifies the user — the international standard for phishing-resistant out-of-band login.

Out-of-band biometric

Approval is confirmed on the user's own phone with fingerprint, face or PIN. Biometric data never leaves the device.

Sub-3-second login

A push notification brings the approval to the phone instantly — faster than typing a password, with far stronger security.

No credential storage

No password database, no shared secret — eliminating the single biggest target in a data breach.

Fallback & recovery

Backup password and SMS / mobile OTP options keep users covered for account recovery and edge cases.

Platform-agnostic

Integrates with Java, .NET, Node.js, Python and serverless back ends — drop it into existing login flows.

Where It's Deployed

Developed by id3 Technologies with DualAuth, id3 Passwordless secures millions of logins for regulated, high-assurance organizations.
