A time-based one-time password (TOTP) is a password that is valid for only one login session, it can protect the password-based authentication from replay attacks. For the router's remote access (login from the WAN interface), you may use TOTP and add a layer of security to your router. This requires a device, usually a mobile phone with a TOTP Authenticator app installed, to generate the time-based one-time password.
