But how do you protect your WhatsApp account?
- First enable two-factor authentication, which requires you to enter a unique PIN to access your account. Never reveal your PIN or verification codes to anyone and do not click on unknown links or attachments.
- Make sure you are properly logged out of WhatsApp Web, especially if your computers are not secure with passwords or biometric data.
- Check the settings of the application to limit the number of information that intruders can receive from your WhatsApp account if it has been compromised. For example, do not allow WhatsApp to share location information and do not allow strangers to add you to group discussions.
- Disable auto-fill option on your phone. As it is a time-saving feature, it also means that your personal information is stored on your phone and any hacker who has access to your phone will be able to see such information.
- When making a particularly sensitive transaction, use a virtual private network (VPN) to protect yourself. The VPN will disguise the Internet Protocol address, making monitoring impossible. It also provides an extra level of encryption.
