TokenCore™ Wearable is a biometric, passwordless, FIDO 2 certified authenticator that eliminates credential theft and account compromise at the hardware level.

It is the only biometric-enforced, cryptographic identity wearable that verifies the human behind every login — in real time.

No password. No code. No fallback.

Authentication is granted when the right person is present. Only then.

Compatible with Google Workspace, Microsoft Entra, Okta, and any platform supporting FIDO2/WebAuthn. Works across Windows, macOS, iOS, and Android. No drivers. No middleware.

FIDO2 certified. SOC 2 compliant. Enterprise-grade identity assurance. Worn on your finger.

Key Features

  • FIDO2 L1 Certified

    Fully compliant with FIDO2 and WebAuthn standards. Phishing-resistant authentication at the protocol level.

  • Tamper-Resistant Secure Element

    Credentials live in an EAL5+ certified secure element. No network path. No cloud exposure. The ring is the vault.

  • Device-Bound Biometrics

    Your fingerprint is stored on-device only. Never transmitted. Identity is bound to you, not to a credential.

  • Upgradeable Technology

    Security posture evolves without replacing hardware. Over-the-air firmware upgrades keep TokenCore™ Wearable current.

  • Proximity-Based Access

    Bluetooth confirms physical presence within 3 feet before authentication begins. Remote relay attacks are structurally impossible.

  • Bluetooth & NFC

    Tap or proximity-based login over BLE 5.4 and encrypted NFC. No drivers. No middleware.

  • Up to 7 Days Battery Life

    Designed for continuous wear. Fully charged in 90 minutes. Five-minute recovery charge when needed.

  • Widely Compatible

    Works with Okta, Microsoft Entra, Google Workspace, and any IAM, SSO, or PAM system supporting FIDO2/WebAuthn.

  • IP67 Rated

    Water and dust resistant. Built for the environments where security matters most.

How to Set Up TokenCore™ Wearable

Setup takes minutes.

  • Step 1: Download the Token App

    Available for Windows, macOS, Android, and iOS. Use it to enroll your fingerprint and configure the device.

  • Step 2: Log in to the service you want to protect

    Sign in to your account as normal.

  • Step 3: Navigate to Account Security Settings

    Find the option to add a security key or multifactor authentication method.

  • Step 4: Follow the on-screen prompts

    Your operating system will guide you through the pairing process. TokenCore™ Wearable handles the rest.

Meet TokenCore™ Wearable

Always With You. Always Verified.

TokenCore™ Wearable is worn on the finger. It stays with the user across every access event — no pocket required, no bag to dig through, no device to forget.

Biometric verification happens inside the ring. The fingerprint is matched on-device, inside an EAL5+ secure element. No biometric data leaves the hardware.

Authentication completes in two seconds. No code. No prompt. No fallback.

Operational in Minutes

Download the Token App.

Enroll your fingerprint. Takes under two minutes.

Tap or approach a compatible device. Authentication completes. From that point forward, every session is verified in real time.

No IT deployment project. No driver installation. No credential provisioning.

Designed for Continuous Wear

Battery life runs five to seven days. A full charge takes 90 minutes. A five-minute recovery charge restores enough power to get through the day.

IP67 rated. Water and dust resistant. Built to go where the user goes.

How It Works

  • 1. Presence Detected

    Bluetooth proximity confirms the user is physically within 3 feet. No session begins without the authorized individual present.

  • 2. Identity Verified

    The fingerprint is matched on-device inside the secure element. No PIN. No fallback. No exception. Access requires the right person.

  • 3. Cryptography Executed

    A domain-bound credential is generated and signed using elliptic curve cryptography. Authentication completes. No credential is transmitted. None exists to steal.

Works with Your Existing Stack

TokenCore™ Wearable is not a replacement.

It sits above your existing IAM, SSO, and PAM — completing the identity layer at the point where failure carries the highest consequence.

Works natively with:

  • Google Workspace
  • Microsoft Entra (Azure AD)
  • Okta
  • Ping Identity
  • Any FIDO2/WebAuthn-compliant platform

No rip-and-replace. No credential migration. No new infrastructure.

Built to Stop Real Attacks

Phishing Is Eliminated

Phishing works by redirecting authentication to a lookalike domain.

TokenCore™ Wearable binds authentication cryptographically to the verified destination. A lookalike domain fails the domain check. The credential is never generated.

There is no credential to intercept. There is no fallback to exploit.

Replay Attacks Have No Surface

Traditional credentials can be captured and reused.

TokenCore™ Wearable generates a unique, domain-bound credential at every authentication event. A captured response cannot be replayed.

The math changes every time. The attack surface disappears.

OTP & Push MFA Are No Longer Enough

One-time codes can be intercepted. Push notifications can be approved under pressure.

TokenCore™ Wearable requires a biometrically verified, physically present individual. Every single time.

No code to intercept. No prompt to approve. No session to hijack.

Why TokenCore™ Wearable Beats Every Other Method

  • vs. Passwords

    Passwords are shared secrets. They are guessed, leaked, phished, and sold.

    TokenCore™ Wearable has no password. There is no shared secret. There is nothing to steal.

  • vs. Authenticator Apps & OTP Codes

    Codes are intercepted in transit. Authenticator apps verify a device, not a person.

    TokenCore™ Wearable verifies the individual: biometrically, in real time, at every access event.

  • vs. Push Notifications

    Push MFA is approved by a human making a judgment call under conditions they cannot always verify.

    TokenCore™ Wearable requires physical presence and fingerprint confirmation. There is no prompt to approve under pressure.

  • vs. Standard Security Keys

    A security key proves device possession. It does not prove the person.

    TokenCore™ Wearable requires both: physical presence and verified biometric identity. Without both, nothing happens.

  • vs. Passkeys

    Passkeys can be synced. A synced credential can be shared.

    TokenCore™ Wearable credentials are hardware-bound and non-transferable. They cannot be synced, shared, or delegated.

Size guide

How to Measure Your Finger for TokenCore™ Wearable

Getting the right fit matters. TokenCore™ Wearable should sit consistently — it authenticates by proximity and fingerprint, so consistent wear drives consistent access. Three ways to find your size:

  • Option 1: Existing Ring Method

    Place a ring you already wear on a ruler. Measure the internal diameter in millimeters.

  • Option 2: String Method

    Wrap a thin strip of paper or string around your finger. Mark where it overlaps. Measure the length in millimeters — this is your circumference. Divide by 3.14 to get your diameter.

  • Option 3: Printable Sizing Guide

    Download the TokenCore™ Ring Sizer for a printable at-home sizing tool with full instructions.
