Two-factor authentication (2FA) is a critical security measure that significantly enhances the protection of user accounts within Sophos systems and other platforms. Its primary purpose is to require users to provide two different forms of identification before gaining access to their accounts. This generally includes something the user knows (like a password) and something the user possesses (like a mobile device for a one-time code).

By implementing this layer of security, Sophos systems mitigate the risk of unauthorized access due to compromised passwords. Even if a malicious actor obtains a user's password, they cannot access the account without the second form of identification, thus significantly reducing the likelihood of breaches. This is especially important in today's environment where cyber threats are increasingly sophisticated.

The other options do not accurately represent the core purpose of two-factor authentication. Streamlining user access and improving network speed are not direct benefits of 2FA; rather, implementing 2FA might initially add a step to the login process. Additionally, eliminating the need for passwords contradicts the essence of two-factor authentication, which combines passwords with an additional layer of security. Therefore, the enhancement of security through dual verification is central to the functionality of 2FA in Sophos systems.
