How to Use Public WiFi Safely

As a general rule, it's best to never use public WiFi. This is because public WiFi networks are less secure than your private home network. Essentially anyone can connect to a public WiFi network, which includes hackers that may try to snoop on your activities and steal your information. Scary, right?

Unfortunately, sometimes you may need to access the Internet in a public place and have no other option than to use public WiFi. Fortunately, there are some things you can do to keep yourself safe even on public networks.

Some Public WiFi Networks are Better than Others

Networks at chain businesses like McDonald's or Starbucks are relatively more secure than other random public networks that you might find on a street corner. Business networks are limited, generally, to customers inside the store. This limits the number of potential hackers that can get to your information. So when you're traveling, try to stick to the well-known networks and avoid any networks you're unfamiliar with. A word of caution, though - any public network is vulnerable to hacking.

Don't Give A Public WiFi Network Personal Information

How To Use Public WiFi SafelySome networks require you to provide an email address or phone number in order to connect to the Internet. Be wary of this - most of the time, it's for marketing purposes. For example, Starbucks might want your information so they can track you across multiple Starbucks WiFi networks. However, if it's an unknown network, they are probably just after your personal information for illegal purposes. Again, refer to the first tip in this article. Steer clear of unknown networks and try to severely limit your use of public WiFi in general.

Don't Use Public WiFi Sites that Require Passwords

If you have to use public WiFi, stick to general browsing. Don't enter any of your passwords to access online accounts, especially banking or other sensitive accounts.

Make Sure to Stay with HTTPS

When browsing, always make sure the website you're visiting is through the encrypted HTTPS connection. When you use HTTPS, the data that travels between you and the website's server is encrypted, meaning it can't be read by potential hackers.

Don't Allow File Sharing

When using a public network, always disallow file-sharing of any type. On a Mac, this means turning off the AirDrop feature. On a PC, this means turning off all Sharing in the Network and Sharing Center. If you don't do this, your computer will be discoverable by anyone on the same network. The wrong person could send you malicious files.

Update Your Operating System

Make sure to stay up to date with your operating system. Any time a new patch or update comes to your device, make sure to download it as it usually contains important security updates that patch any discovered vulnerabilities.

Use a VPN

The best option for staying safe is to use a Virtual Private Network (VPN). It connects your device to a secure server and encrypts all of your data. This is the most expensive option, but it's definitely the most secure. If you don't want to pay for a VPN, follow the above advice, and use caution when using public WiFi.

As previously stated, the best way to keep yourself safe is to avoid public WiFi at all costs. If possible, use your mobile phone's hotspot instead if you absolutely have to connect to the Internet.
