The USB devices communicate with the host computer using the human interface device (HID) protocol, essentially mimicking a keyboard. [9] [failed verification – see discussion] This avoids the need for the user to install special hardware driver software in the host computer and permits application software (such as a browser) to directly access the security features of the device without ...

This page in a nutshell: Administrators and editors with advanced permissions should ideally enable two-factor authentication for account security, and can do so by following this guide. Particular attention should be paid to the section of this guide on scratch codes — if you don't keep these codes and encounter a problem with your 2FA ...
6-digit codes are commonly provided by proprietary hardware tokens from a number of vendors informing the default value of d. Truncation extracts 31 bits or log 10 ( 2 31 ) ≈ 9.3 {\textstyle \log _{10}(2^{31})\approx 9.3} decimal digits, meaning that d can be at most 10, with the 10th digit adding less variation, taking values of 0, 1 ...
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").
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.
The former is termed server-side authentication - typically used when authenticating to a web server using a password. The latter is termed client-side authentication - sometimes used when authenticating using a smart card (hosting a digital certificate and private key).
