To secure WhatsApp, several key steps enhance privacy and protect against unauthorized access:

• Enable two-factor authentication (2FA) with a 6-digit PIN to add an extra layer of account security.
• Customize privacy settings to control who can see your profile information, last seen, and who can add you to groups.
• Use WhatsApp's built-in end-to-end encryption, which is active by default, ensuring messages and calls are private and cannot be accessed by anyone else, including WhatsApp.
• Regularly review and log out of any unknown linked devices in WhatsApp Web or Desktop.
• Avoid sharing your WhatsApp verification code or 2FA PIN with anyone to prevent account takeover.
• Keep the app and your phone's operating system updated to protect against vulnerabilities.
• Use a screen lock on your phone and enable WhatsApp's app lock feature to prevent unauthorized access.
• Be cautious when sharing sensitive information or media and consider using disappearing messages for added privacy.
• Avoid using public Wi-Fi for WhatsApp without a VPN, as public networks can be insecure.
• Employ a reputable antivirus app to protect your device from malware.
