Use secure messaging apps for sensitive info.

Best Practices for Secure Messaging

• Use apps with end-to-end encryption (E2EE) by default.
• Minimize metadata exposure (e.g., use VPN, avoid phone number signup).
• Enable 2FA, use disappearing messages, and avoid public Wi-Fi without protection.
• Prefer open-source apps, keep devices updated, and avoid sharing sensitive info.
• Disable cloud backups for sensitive chats and verify contacts manually.
