TL;DR: Use the Apple Passwords app to store the “Secret Key” from a website, which turns your Touch ID into a code generator.

Step-by-Step Guide: Touch ID for 2FA

  1. Get the Secret Key:

    • On the website’s 2FA setup page, look for “Enter key manually” or “Can’t scan QR code.”
    • Copy the alphanumeric string (the “Secret Key”) provided by the site.

  2. Open the Passwords App:

    • Launch the Passwords app (on macOS Sequoia or later) or go to System Settings > Passwords.
    • Authenticate with Touch ID.

  3. Create or Edit an Entry:

    • Find the entry for the website (e.g., ea.com) or click the + (plus) icon to create a new one.
    • Click Set Up Code… or Add Verification Code.

  4. Paste the Key:

    • Select Enter Setup Key.
    • Paste the alphanumeric string you copied in Step 1.

  5. Finish the Link:

    • The Passwords app will now show a 6-digit code that changes every 30 seconds.
    • Enter this code back on the website to verify the link.

How it works next time

The next time you log in to EA:

  • The site will ask for your 2FA code.
  • Open your Passwords app (or use the AutoFill prompt above your keyboard).
  • Use Touch ID to view the entry.
  • Copy the current code and paste it into the site.
