In addition, be careful with emails from unknown senders and avoid links to access secure websites, always type the URL into the browser instead. Whenever possible, avoid using public Wi-Fi to login to sensitive accounts.

- Even when using secure Wi-Fi, limit your use to activities that do not require authentication.
- Manually log out of secured sessions whenever you’re not using them.
- Use sites that force HTTPS protocol, whenever possible.
- Apply multiple authentications to accounts if this option is available.
