How Do I Use an Open Wi-Fi Hotspot Safely?

//

I’ve returned to the same coffee shop where I was a few months ago, where I noticed my email had been hijacked/hacked. This time, I’m using my phone, but the last time, when I noticed the hack, I was using my computer and doing email over an open-internet, free Wi-Fi network.

Do you think that could be the source of the problem or just a coincidence? I’m still afraid to do email from here.

It definitely could have been. Unfortunately, it’s hard to say for sure; it could have been something else unrelated.

As we can’t really diagnose the past, let’s look ahead instead.

It can be absolutely safe to send and receive email from a coffee shop or any other location that provides unsecured or “open” Wi-Fi. In fact, I do it all the time.

But to ensure your safety, you do have to follow some very important practices.

Does Having a Publicly Visible Wi-Fi Password Add Security Compared to an Open Wi-Fi Hotspot?

//
I handle the Wi-Fi hotspot for a library and have been using WPA2 with an openly distributed passphrase. Another library has no security whatsoever. Is there a greater risk using no security because for our library the passphrase is so openly available to possibly bad guys?

The short answer is absolutely!

Using WPA2 with a password – even a publicly visible one – adds significant levels of security beyond an open Wi-Fi hotspot. Yes, even if everybody in the room knows the password.

When you’ve got an open Wi-Fi hotspot, all of the information that’s being transmitted by each of the computers connected to that hotspot is being transmitted in the clear. That puts the onus of security on each individual computer user. That’s not necessarily a good assumption to make.
