Published: April 1, 2024 |3 min read By now, you probably know the benefits and perhaps even the perils of using public Wi-Fi. Sure, it's convenient, free, and sometimes it's even faster than some home Wi-Fi networks. So, it makes sense that most people say they access public Wi-Fi three to four times a month, with the most common places being grocery stores, hotels, airports and restaurants1. But did you know these are also prime places to have information compromised while using public Wi-Fi?  #### Jump to a Section 1. [What is a VPN and how can one help?](https://www.t-mobile.com#1) 2.

Isn't that safer? It's only as safe as passwords are strong. And strong they are not. In fact, weak credentials were the cause of nearly 70 percent of [Wi-Fi security](https://www.t-mobile.com/home-internet/the-signal/speed/wi-fi-security-essential-protections) issues, with the rest being caused by vulnerable, unpatched devices with firmware that hasn’t been updated2. This is where VPNs come in handy. ## __What is a VPN and how can one help?__ A VPN (Virtual Private Network) is a good solution for those who value not only security, but privacy and convenience, too. VPNs work by routing traffic to a server operated by your VPN service of choice and hiding your [IP address](https://www.t-mobile.com/home-internet/the-signal/internet-help/what-is-my-ip-address-and-how-do-i-change-it), which is like a digital version of your return address. Without it, anyone who knows your IP address can access what, when, and where you've searched online. In fact, your entire search history is exposed as soon as you connect to a browser over an unprotected connection, making it a virtual playground for hackers and other bad actors. ### __How does a VPN protect you on public Wi-Fi?__ With a VPN, because your web traffic comes from the VPN's server, your IP address is hidden, making it more difficult to track what you're doing on both public and home Wi-Fi connections. This can help protect you in several ways: - Your browsing history stays private. - Your personal information remains secure. - Your devices are better protected. ### __How do I get a VPN?__ There are several good VPN services out there, but you will have to pay a fee.
