MasterCard SecureCode uses OTAC to confirm a user's identity One time authorization code as used in Yammer's desktop client. A one-time password (OTP), also known as a one-time PIN, one-time passcode, one-time authorization code (OTAC) or dynamic password, is a password that is valid for only one login session or transaction, on a computer system or other digital device.
C T is the count of the number of durations T X between T 0 and T, T is the current time in seconds since a particular epoch, T 0 is the epoch as specified in seconds since the Unix epoch (e.g. if using Unix time, then T 0 is 0), T X is the length of one-time duration (e.g. 30 seconds).
HMAC-based one-time password (HOTP) is a one-time password (OTP) algorithm based on HMAC.It is a cornerstone of the Initiative for Open Authentication (OATH).. HOTP was published as an informational IETF RFC 4226 in December 2005, documenting the algorithm along with a Java implementation.

The one-time pad is an example of post-quantum cryptography, because perfect secrecy is a definition of security that does not depend on the computational resources of the adversary. Consequently, an adversary with a quantum computer would still not be able to gain any more information about a message encrypted with a one time pad than an ...
