An extension of the HMAC-based One-time Password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard RFC 6238. In general, there are two approaches to OTP generation, either Mathematical-algorithm-based or Time-synchronized.The former, as the name suggests uses a complex mathematical algorithm, typically a cryptographic hash function in a hash chain mode, together with a secret key to generate the password.
