Public Wi-Fi: Connect with caution

Simple ways to protect your information on the go

Whether you’re attending a conference, traveling for a meeting, or working from a coffee shop between appointments, public Wi-Fi can be a convenient way to stay connected.

But convenience comes with risks.

Public networks and shared computers are often used by many people. That means you don’t always know who else is on the network—or what security measures are in place.

A few simple precautions from the National Cybersecurity Alliance can help protect your accounts, devices, and sensitive information.

Be aware of your surroundings

While you work, pay attention to who can see your screen. Someone sitting nearby may be able to view sensitive information or watch you enter passwords.

This simple form of spying—sometimes called “shoulder surfing”—can expose more information than you realize.

Also, pay attention to the network you’re joining.

Cybercriminals have been known to create fake Wi-Fi hotspots with names designed to look legitimate, such as “Airport Free WiFi,” “CoffeeShop_Guest,” or “Hotel Lobby WiFi.”

Before connecting, confirm the correct network name with staff or posted signage. Avoid networks that require unexpected downloads, request excessive personal information, or trigger unusual browser warnings.

Clean up before you leave

Closing a browser window is not enough. Many sites keep users signed in unless they actively log out.

If using a public computer, take a few extra moments before walking away.

• Log out of all accounts
• Clear your browser history and cookies
• Remove any saved passwords
• Close all browser windows

Using a private or incognito browser window can automatically delete your data as well.

These steps help ensure your information isn’t available to the next user.

A little caution goes a long way

Public Wi-Fi and shared computers aren’t inherently dangerous, but they do require extra awareness. A few simple precautions can significantly reduce your risk.

When handling work-related or sensitive information, consider using your phone’s hotspot instead of public Wi-Fi whenever possible. It’s often a safer option when you’re away from the office.

It’s also important to use strong, unique passwords and enable multi-factor authentication on your accounts. Even if a password is compromised, multi-factor authentication provides an additional layer of protection.

By making smart choices before you connect, you can enjoy the convenience of public Wi-Fi while keeping your personal and professional information secure.
