Quick Setup Guide

This guide shows how to use your Thetis FIDO2 Passkey Security Key devices for two-factor authentication (2FA), using Facebook as an example. These steps apply to any service supporting FIDO2.

Important: You will need to set a 6-digit PIN during setup. Make sure to remember it, as it’s required for future use. We strongly recommend using a PC or Mac with a supported browser (Chrome, Edge, Safari) for your first setup.

    Step 1: Access Account Security

    1. Open Browser: Launch a supported browser on your device.
    2. Visit Security Settings: Go to the Facebook Password & Security Section and log in.
    Facebook Security Center

    Step 2: Set Up Thetis Key for 2FA

    1. Go to 2FA Settings: In the security settings, select "Two-factor Authentication".
    2. Select Security Key: Choose "Security key" as the 2FA method.
    Facebook 2FA Choose Key
    1. Insert Thetis Key: Plug the Thetis Key into your USB port and follow the on-screen prompts.
    2. Enter PIN: When asked, enter the PIN you previously set. If you haven’t set a PIN, you’ll be prompted to create one now. Ensure it is at least 6 characters.

     Finish Setup: A confirmation will show that 2FA with the Thetis Key is now active.

    Troubleshooting

    • Key Not Recognized: Make sure the key is fully inserted. If not working, try another USB port or restart your device.
    • Setup Issues: Ensure your device/browser meets the requirements and that the Thetis Manager software is correctly configured.
