Why You Should Avoid Using Public WiFi

Using public WiFi is a no-no unless you want to hand your private data over to hackers.

This is another example of how to fight hackers. We’ve already looked at two-factor authentication and encryption.

Public WiFi might seem like the perfect way to make your monthly-allocated data usage go further, but it’s fraught with dangers.

Public WiFi opens the door to hackers

When you’re out and about, your smartphone will detect many WiFi networks. Some will be locked, requiring a password to log on. Others will purport to be public access, free services.

However, the thing you have to remember is that these free, public access networks are also insecure.

What does that mean?

It means that when you use them, everything you type is in clear text and can be read, accessed, recorded or taken over by anyone with the correct equipment.

Can you make public WiFi safe?

If you rely on these public WiFi services, there is a solution to remove, or at least reduce the risk of hacking.

The solution is to use a Virtual Private Network (VPN), which scrambles your communications making them unreadable.

If a VPN isn’t provided by a business firewall, you can buy applications for about £3 a month. These will scramble all communications through insecure connections.  Once a VPN is being used, there’s no way the ISP or anyone else can read or record what you’re browsing.

The moral of this post

If you have to use public WiFi when you’re out and about, make sure you use a virtual private network. If you don’t you run the risk of losing your privacy and, possibly, your data.
