What feature can enhance user security during sign-in?

Two-Factor Authentication (2FA) significantly enhances user security during sign-in by adding an additional layer of protection beyond just the username and password. This security measure requires users to provide two forms of identification before gaining access to their account. Typically, the first factor is something the user knows (like their password), while the second factor can be something they have (like a mobile device that receives a one-time code) or something they are (biometric verification such as fingerprint or facial recognition).

The implementation of 2FA helps to mitigate risks associated with potential password breaches. Even if an attacker manages to obtain a user's password, they would still require the second factor to successfully gain access to the account. This greatly reduces the likelihood of unauthorized access and strengthens overall account security.

In contrast, options like Password Recovery Options, while useful for account recovery, do not prevent unauthorized access. Multi-User Access pertains to allowing multiple logins, which could weaken security further if not managed properly. Guest Access, while convenient for temporary users, can also introduce vulnerabilities by allowing unverified access without appropriate security checks.
