Here’s how you can navigate the world of public Wi-Fi safely.
Verify the Network’s Authenticity

While many mobile apps use encryption, it’s harder to ascertain their security compared to websites. Be cautious about entering personal information into apps when using public networks.

Keeping your antivirus software updated can help safeguard your device from malware, viruses, and other cyber threats.
