Greensboro, NC -- So many of us use public wi-fi --- when we're at restaurants, airports, you name it. Instead of hoping a crook isn't hacking into the wi-fi - know how to protect yourself. Experts tell 2 Wants to Know the answer is a virtual private network or VPN.
When you log onto public wifi, it's like an invisible string is connecting your computer to the internet router. A string which hackers can attach to and steal your information. But identity theft experts say using a VPN can cut that invisible string by encrypting your data.
"Once you get a VPN and log into that virtual private network, you've basically made yourself invisible," ID Theft Resource Center President Eva Velasquez said. "It's a small and not very costly step you can take to protect yourself."
VPN's should cost just a few dollars a month and are relatively easy to install. All you have to do is follow the directions from the company you pick. The website LifeHacker ranks the five best VPN service providers as BolehVPN, Astrill VPN, Hamachi, Private Internet Access and Witopia.
