Question

smart start preschool employees use mobile devices to sign in to network computers. what could be used as a secondary form of authentication to establish high - security multifactor authentication for the company? fingerprints tokens smart cards badges

Explanation:

Multifactor authentication (MFA) typically combines something you know (e.g., password), something you have (e.g., mobile device), and something you are (biometrics). Fingerprints are a biometric factor. Tokens and smart cards are "something you have" (but if mobile devices are already used as one factor, adding another "something you have" might not be as strong as adding a biometric). Badges are also "something you have". Since the question asks for a secondary form (assuming mobile device is one factor), a biometric like fingerprints adds a different type of factor (something you are) for higher security.

Answer:

Fingerprints
