Free public WiFi is everywhere — in cafes, airports, hotels, malls, and parks. While it feels convenient, it can also expose your personal information to hackers.

The good news? With Trend Micro ID Protection's WiFi Security, you can enjoy public WiFi with peace of mind.

In this guide, you’ll learn:

📈 The Rise of Free Public WiFi

With smartphones everywhere, public WiFi usage has surged. Cities, businesses, and transport hubs now provide free hotspots to attract visitors and improve convenience. While they’re helpful, these networks can also create easy entry points for cybercriminals.

🛡 Is Public WiFi Safe?

Public WiFi networks can be safe or unsafe depending on security measures. Unfortunately, many are open, wifidangers, and easily exploited — making your personal data vulnerable to theft in seconds.

🚨 The Dangers of Public WiFi

  • Lack of Encryption — Without encryption, sensitive data can be intercepted during transmission.
  • Unsecured Networks — Anyone can join, and attackers can set up fake hotspots to steal data.
  • Man-in-the-Middle Attacks — Hackers can monitor your activity, steal credentials, and inject malware.
  • Untrusted Administrators — Rogue admins can deliberately misuse public WiFi to collect user data.

✅ How to Stay Safe on Public WiFi

  1. Check Network Security

    Before connecting, check if the network has a padlock icon or strong encryption. Avoid unfamiliar or unsecured networks.

  2. Use a VPN

    A Virtual Private Network (VPN) encrypts your traffic and hides your IP address.
    With Trend Micro ID Protection, you get built-in VPN as part of your privacy protection.

    1. Open the Trend Micro ID Protection App.
    2. Tap the Privacy tab at the bottom.
    3. Toggle ON Privacy protection.
    4. Follow prompts to allow VPN configuration and enter your passcode.
  3. 💡 Enable WiFi Security — Your First Line of Defense

    Here’s how to turn it on:

    1. Open the Trend Micro ID Protection app.
    2. Go to the Privacy tab you see at the bottom.
    3. Tap the WiFi Security tab to see and check your WiFi connection.
  4. Turn Off Auto-Connect

    Prevent your phone from connecting to public WiFi automatically.

    • For iPhones/iPads:
      1. Open Settings → WiFi.
      2. Tap the (i) icon next to the network.
      3. Toggle Auto-Join OFF.
    • For Android:
      1. Open Settings → WiFi.
