She disclosed valuable tips for enhancing WhatsApp security in a post on X, formerly Twitter

1. Default Encryption: Encryption (E2EE) is automatically activated, providing a baseline level of security.

2. Disappearing Messages: Activate the Disappearing Messages feature for all your chats. This proves useful in situations where trust is uncertain, or devices that might pose a security risk.

Go to Settings > Privacy > Default message time. Pick a timer like 24 hours, 7 days, or 90 days, and all your messages, including pictures and videos, will vanish after that time.

3. Encryption for Backups: Choose to enable or disable E2EE Backups. This precautionary measure prevents Google and Apple from accessing your backup data.

Go to Settings > Chats > Chat backup. Turn on the option for end-to-end encrypted backup.

4. Chat Lock for Sensitivity: Utilise the Chat Lock feature for chats that contain sensitive information. This proves helpful in securing your chats when your device may be susceptible to unauthorised access.

Go to the chat you want to lock, click on the profile name, and choose "lock chat" to secure it with a passcode.

5. Secure Calls: Utilise features like Silence Unknown Calls and Call Relay for additional security during voice calls. Silence Unknown Calls combats 0-click attacks, while Call Relay safeguards against IP surveillance of your calls.

Go to Settings > Privacy > Calls and activate "Silence unknown callers" to filter out calls from unfamiliar numbers.

By making these simple adjustments in your WhatsApp settings, you can fortify your account against potential hacks and bolster your overall security.
