Two-factor authentication (2FA)

1. Open Settings → Security.
2. Enable two-factor authentication and scan the QR code with an authenticator app.
3. Save your authenticator recovery codes offline. Each code works once.
4. Wallet PIN backup is separate. Set that up in Settings → Wallet.
5. Confirm with a code from your authenticator.

If you lose your authenticator, use a recovery code, then set 2FA up again.
