Two-factor authentication (2FA) is a security feature designed to protect your Tello account by requiring two methods of verification to log in — typically your password and a security code. This feature adds an extra layer of protection to keep your account secure.

When 2FA is enabled for your Tello account, you’ll need to provide a one-time security code from a third-party authenticator app (like Google Authenticator or Authy) along with your password. This ensures that only you can access your account, keeping it safe.
