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 .
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.
If a strong two-factor authentication system is used, the stolen passwords cannot be stored and later used because each one-time password is valid for only one authentication session, and will fail if tried a second time. [1] multiOTP is a PHP class library. The class can be used with any PHP application using a PHP version of 5.3.0 or higher.
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.

2FA is like a software version of the security token devices used for online banking in some countries. Two-factor authentication ( 2FA ) is a method of adding additional security to your account. The first "factor" is your usual password that is standard for any account.
