How can individuals protect their privacy online?

Using complex passwords and enabling two-factor authentication are effective methods for individuals to protect their privacy online. Complex passwords make it significantly harder for unauthorized individuals to gain access to accounts, as they are less predictable and often longer and incorporate a mix of characters. Two-factor authentication adds an additional layer of security by requiring not only a password but also a second form of identification, such as a text message code or an authentication app. This means that even if someone manages to obtain a password, they would still need the second factor to access the account, greatly enhancing overall security.

Other options such as avoiding social media, while potentially reducing exposure to certain types of risks, do not comprehensively address the multitude of privacy threats that can occur online. Sharing personal information freely directly contradicts the goal of protecting privacy and can lead to identity theft and other security breaches. Lastly, frequently visiting unsecured websites can expose individuals to various risks including malware and phishing attacks, thereby compromising their privacy rather than protecting it.
