Get Prepared

Unbox and check your ATKey.Badge.

Before you begin, make sure both your ATKey.Badge (ATKey.Card NFC and holder device) are ready for setup

  1. Unbox your ATKey.Badge and check the card and holder device. Insert your ATKey.Card NFC into the holder, gently press and slide it toward the bottom, and ensure the fingerprint sensor aligns with the window.

  2. You’ll find an 8-digit number on the card next to the FIDO2 logo — this is your ATKey keycode, a unique identifier for your ATKey. You may need your keycode later for support, warranty, or enterprise registration.

  3. Get your PC device prepared:

    • Windows

    • Mac

    • To set up with a mobile device, please refer to this

  4. Connect the ATKey.Badge to the PC; a solid blue LED indicates the device is powered on.

Enroll Your Fingerprint

Your fingerprint is the key to your ATKey.Badge — it’s securely stored inside the device and never shared.

You can perform fingerprint enrollment on different operating systems — simply power the key and follow the UI instruction and device’s LED guidance.

    1. Go to Settings → Accounts → Sign-in options → Security Key

    2. Click Manage→ Click the holder button when the LED flashes yellow → Enter the Setup dialogue

    3. Follow the on-screen instructions to create a Security Key PIN — required by FIDO2 and used for fingerprint management once enrollment is complete.

      • Click the Add button in the Security Key PIN section → Enter PIN → Click OK

    4. Follow the on-screen instructions to enroll your fingerprint. Fingerprint enrollment requires continuous 4 successful touches on the sensor. For best results, touch from different angles during the enrollment process to ensure your fingerprint is fully captured and easily recognized in future authentications.

      • Click the Add button in the Fingerprint section → Enter PIN → Touch the fingerprint sensors 4 times when the LED flashes blue

    5. You can enroll fingerprints from different fingers to match your typical usage habits and ensure easier access across various devices.

    1. Open Chrome browser

    2. Navigate to Settings → Privacy & Security → Security → Manage Security Keys (chrome://settings/securityKeys)

    3. Follow the on-screen instructions to create a Security Key PIN — required by FIDO2 and used for fingerprint management once enrollment is complete.

      • Click Create a PIN → Click the holder button when the LED flashes yellow → Enter the Create PIN dialogue

    4. Follow the on-screen instructions to enroll your fingerprint. Fingerprint enrollment requires continuous 4 successful touches on the sensor. For best results, touch from different angles during the enrollment process to ensure your fingerprint is fully captured and easily recognized in future authentications.

      • Click Fingerprints → Click the holder button when the LED flashes yellow → Enter the PIN → Enter the Manage fingerprints dialogue

    5. You can enroll fingerprints from different fingers to match your typical usage habits and ensure easier access across various devices.

      • Click Add → Touch the fingerprint sensors 4 times when the LED flashes blue → Name the fingerprint template

Fingerprint Enrollment Tips:

  • Make sure your finger and the sensor are clean and dry before you start.

  • Choose a finger that you naturally use when touching the key.

  • Enrollment requires four successful touches to complete. For each touch, place your finger on the sensor for about one second to allow the device to capture a full fingerprint. If any errors occur during the process, you will need to restart the enrollment.

  • Test your fingerprint immediately to confirm smooth recognition.

  • If recognition fails often, re-enroll the same finger for improved accuracy.

  • If there’s any unexpected issues happen, try to re-plug the key or restart the session on your PC device

Frequently Asked Questions

  • The device allows for 15 consecutive failures (as per the ATKey.Card NFC specification).

  • Consistent with other ATKey products, the device will block any Registration or Authentication operations that require User Verification (UV). To unlock the fingerprint functionality, you must connect the device to a client and perform an operation using a PIN.

  • The counter is shared. The internal hardware (ATKey.Card NFC) maintains a single counter for remaining fingerprint retries, meaning a failure on NFC counts towards the same limit as a failure on USB.
