Protect your code and repositories with YubiKey authentication for GitHub. This concise guide shows you how to register a YubiKey as a passkey (FIDO2/WebAuthn), add a backup key, troubleshoot common issues, and purchase a genuine device in the EU.
Why Secure Your GitHub Account with a YubiKey
GitHub accounts hold valuable code, secrets, and project access. A YubiKey adds phishing-resistant, hardware-backed security. Unlike SMS or app codes, a physical key must be present to sign in, greatly reducing account-takeover risk for individuals, teams, and organisations across Europe.
Step-by-Step Setup Guide
- Go to github.com and click Sign in. Enter your username and password.
- Click your profile icon (top right) → Settings.
- Open Password and authentication.
- Under Passkeys, click Add passkey and choose Security key in the browser pop-up.
- Create a memorable PIN when prompted. Give your key a clear name (for example, “YubiKey”).
- Click Done to finish setup.
- Test the login: Sign out, sign back in, select Use passkey → Security key and tap your YubiKey to authenticate.
Tip: If you carry multiple keys, apply a distinctive cover or label to tell them apart at a glance. You can find our range of YubiStyle covers at Trust Panda.
How to Add Backup Keys
- Repeat the same Add passkey flow with your second YubiKey.
- Name it “Backup YubiKey” (or similar) and store it securely, such as in a safe drawer or off-site location.
- Periodically test your backup key to ensure it still works.
Troubleshooting
- Key not detected: Try another USB port, reconnect the key, or use a different supported browser. We use Chrome here at Trust Panda.
- PIN forgotten: Reset the key with Yubico Authenticator, then re-register it in GitHub. Remember that if YubiKey is your only MFA option, you may need help from GitHub support to regain access to your account.
- No “Use passkey” option: Update your browser or operating system to the latest version and ensure WebAuthn or passkeys are supported.
- Multiple accounts: Give each registered key a unique label in GitHub to avoid confusion.
