Here are some steps you can take to secure your WhatsApp account:
Enable two-step verification: This is an additional layer of security that requires you to enter a PIN code that you create when you set it up. This helps prevent unauthorized access to your account even if someone has your phone number.
Use a strong password: Make sure your WhatsApp password is unique and not easily guessable. Avoid using common words or phrases.
Verify your contacts: Make sure you only communicate with people you know and trust. Do not open suspicious links or attachments, and do not share personal information with strangers.
Use the latest version of WhatsApp: Keep your WhatsApp app up to date to ensure that you have the latest security updates.
Disable cloud backups: If you're concerned about the privacy of your chats, you can disable backups to cloud services like Google Drive or iCloud. This will ensure that your messages are only stored locally on your device.
Lock your WhatsApp: Use the built-in app lock feature to prevent unauthorized access to your chats. This will require you to enter a PIN, fingerprint, or facial recognition to unlock the app.
Enable end-to-end encryption: WhatsApp uses end-to-end encryption to protect your messages from being intercepted. Make sure this feature is enabled in your settings.
