A network engineer is configuring secure access to the corporate VPN. The policy states that users must first enter their Active Directory domain password and then supply a six-digit code generated by a hardware token they carry. Which authentication approach meets this policy requirement?
The policy requires two distinct factor types: a knowledge factor (domain password) and a possession factor (hardware-generated one-time code). Together, these constitute multifactor authentication, making it more resistant to compromise than a single factor alone. Strong password complexity and expiration policies only strengthen the knowledge factor, not add another factor. Single sign-on streamlines credential reuse but does not automatically introduce additional factors. One-time password authentication by itself is still a single possession factor unless combined with another factor, so it does not meet the stated requirement.
