It is important to use caution when connecting to public Wi-Fi networks. Here are some steps you should take to maximize your security:

1. Opt for more secure networks. Look for Wi-Fi networks that require a password or have additional security enhancements enabled.
2. Use a virtual private network (VPN). VPNs encrypt your data and make it difficult to be accessed by others.
3. Avoid logging into personal or sensitive accounts. When possible, avoid accessing online banking, credit card, social media, email, and any other secure account.
4. Make sure your device is updated. Use the latest software and keep your device updated.
5. Activate your firewall. A firewall can be your first line of defense against malicious attacks.
6. Be mindful of shared resources. Some devices may be vulnerable to attacks when connected to the same public networks.
