# Two-Factor Authentication (2FA)

2. Click **Enable 2FA**.
3. Add your 2FA key to your authenticator app (such as Google Authenticator or Authy).
4. Enter the **6-digit code** from your authenticator app.
5. Save your **Recovery Key** somewhere secure.
6. Finish setup.

### Lost access to your 2FA?

If you lose access to your authenticator app, you can use your **Recovery Key** to log in.

Once you log in with the recovery key, **2FA will be disabled**, and you can set it up again.

**Never share your 2FA Recovery Key** — not even with Polymarket staff.&#x20;

If someone gains access to your recovery key, **they can access your account and funds**.
