The following is a general comparison of OTP applications that are used to generate one-time passwords for two-factor authentication (2FA) systems using the time-based one-time password (TOTP) or the HMAC-based one-time password (HOTP) algorithms.
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.
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 .
First YubiKey USB token of the FIDO standard in 2014. The YubiKey is a hardware authentication device manufactured by Yubico to protect access to computers, networks, and online services that supports one-time passwords (OTP), public-key cryptography, authentication, and the Universal 2nd Factor (U2F) and FIDO2 protocols [1] developed by the FIDO Alliance.
Common secure methods for one-time pad delivery are quantum key distribution, a sneakernet or courier service, or a dead drop. The implementation does not feature an unconditionally secure authentication mechanism such as a one-time MAC. The pad is reused (exploited during the Venona project, for example). [25]
Google Authenticator is a software-based authenticator by Google.It implements multi-factor authentication services using the time-based one-time password (TOTP; specified in RFC 6238) and HMAC-based one-time password (HOTP; specified in RFC 4226), for authenticating users of software applications.
As of 2003, RSA SecurID commanded over 70% of the two-factor authentication market [10] and 25 million devices have been produced to date. [citation needed] A number of competitors, such as VASCO, make similar security tokens, mostly based on the open OATH HOTP standard.
