What type of authentication uses temporarily issued tokens for securing access?

The correct choice refers to multifactor authentication, which enhances security by requiring multiple forms of verification to access systems or data. This approach often includes a temporary token, which can be sent via SMS, email, or generated by an authentication app. These tokens typically expire after a short period, reducing the risk of unauthorized access significantly. The temporary nature of the issued tokens means that even if a token is intercepted, it remains useless beyond its short lifespan, thereby providing a strong layer of security.

While mandatory access control focuses on enforcing access policies based on predefined labels for data and user roles, it does not inherently involve time-sensitive tokens. On the other hand, roles and nondiscretionary access control refer to methodologies of assigning permissions and access rights based on user roles or strict policies, which also do not include the concept of temporarily issued tokens. Therefore, the option focusing on multifactor authentication best addresses the use of temporary tokens for securing access, highlighting its relevance in modern security practices.
