Use TOTP as Two Factor Authentication (2FA) for Remote Access

In addition to providing advanced security modes of mOTP and 2-Step Authentication for remote administrators to log in to the Vigor router, the Vigor router now has another option, namely TOTP, to meet customer needs. A time-based one-time password (TOTP) is a temporary passcode generated by an algorithm that uses the current time of day as one of its authentication factors. The password is valid once, and it can protect the password-based authentication from replay attacks. For the router’s remote access (login from the WAN interface), we may use TOTP and add a layer of security to the router. This requires a device, usually a mobile phone with a TOTP Authenticator (Google Authenticator) app installed, to generate the time-based one-time password.
