Overview[1]#

HMAC-based One-Time Password Algorithm is an (HOTP) is a cornerstone of Initiative For Open Authentication Initiative for Open Authentication.

HMAC-based One-Time Password Algorithm is a One-Time Password System

HMAC-based One-Time Password Algorithm is an specific algorithm to create One-Time password.

HMAC-based One-Time Password Algorithm was published as an informational IETF RFC 4226 in December 2005, documenting the algorithm along with a Java implementation.

Since then, the HMAC-based One-Time Password Algorithm algorithm has been adopted by many companies worldwide. The HMAC-based One-Time Password Algorithm algorithm is a freely available open standard.

HMAC-based One-Time Password Algorithm uses a secret key and a counter as input to the HMAC-SHA1 Message Authentication Code (MAC) algorithm, truncates the calculated MAC value and converts it to a to human readable code, usually a 6-digit number.
