Comparison of OTP applications. 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 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.
Proprietary freeware (some versions were under Apache License 2.0) 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 ...
We'll send you a text or call you with a new code that needs to be entered at sign-in. The phone number we contact you with may be different each time. Enable 2-step for phone. 1. Sign in to your Account Security page. 2. Next to "2-Step Verification," click Turn on. 3. Select Phone number for your 2-step verification method. 4.
The RSA SecurID authentication mechanism consists of a "token"—either hardware (e.g. a key fob) or software (a soft token )—which is assigned to a computer user and which creates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card's factory-encoded almost random key (known as the "seed").
Mobile phone-based authentication. Two-factor authentication over text message was developed as early as 1996, when AT&T described a system for authorizing transactions based on an exchange of codes over two-way pagers. Many multi-factor authentication vendors offer mobile phone-based authentication.
RSA Security LLC, [5] formerly RSA Security, Inc. and trade name RSA, is an American computer and network security company with a focus on encryption and encryption standards. RSA was named after the initials of its co-founders, Ron Rivest, Adi Shamir and Leonard Adleman, after whom the RSA public key cryptography algorithm was also named. [6]
A GoldKey security token connected to a laptop. A security token is a peripheral device used to gain access to an electronically restricted resource. The token is used in addition to, or in place of, a password. [1] Examples of security tokens include wireless key cards used to open locked doors, a banking token used as a digital authenticator ...
