Free Wi-Fi comes with a cost. Usually, that cost is your personal data. Here's why you should be extremely cautious next time you're at a Starbucks or an airport lounge.
The "Captive Portal" Trap
Most public Wi-Fi networks use a captive portal that requires an email address. They aren't just doing this for "security"—they are building a marketing database to sell to local businesses.
Man-in-the-Middle Attacks
Public networks are often unencrypted. Hackers on the same network can intercept the data you send. If you're giving away your primary email and a "common" password, you're handing them the keys to your life.
Protection Strategy:
- Always use a VPN.
- Use testsmail for the login portal.
- Forget the network as soon as you're done.
Don't trade your long-term privacy for 20 minutes of "free" internet. Be smart, stay secure.
