Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) using the current time as a source of uniqueness. As an extension of the HMAC-based one-time password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard RFC 6238 .
A typical use case occurs when a web user submits a web form on a web page that uses CGI. The form's data is sent to the web server within a HTTP request with a URL denoting a CGI script. The web server then launches the CGI script in a new computer process , passing the form data to it.
