Public Wi-Fi is a convenient option for staying connected while on the go. Whether you’re at a café, airport, or hotel, the ability to access the internet without using your mobile data is undeniably helpful. However, be wary: public Wi-Fi can be dangerous.
Unlike your home or office network, public Wi-Fi usually lacks effective security measures. Connecting to it is akin to walking through a crowded city street with your wallet wide open. Cybercriminals can easily steal your sensitive data, including your passwords and credit card information. To ensure your online safety, it's essential to understand how to protect yourself on public Wi-Fi.
How can you stay safe online while using public Wi-Fi?
While connecting to public Wi-Fi has numerous risks, you can keep your online activities private by doing the following:
Use a virtual private network (VPN)
A VPN encrypts your device’s connection to the internet, making your data unintelligible to hackers even if it is intercepted. But do not use just any VPN; select one with a proven track record of privacy protection and advanced encryption capabilities. Avoid free VPNs, as their providers may compromise your privacy or monetize your data.
Enable multifactor authentication (MFA)
MFA boosts security by requiring you to prove your identity multiple times before you can access your accounts. This commonly involves a combination of knowledge-based factors (such as a password), possession-based factors (such as a code), or biometric factors (such as your fingerprint). Many services, including email and social media platforms, offer MFA. By enabling it, you can prevent unauthorized account access, even if your login credentials become compromised.
Disable automatic connections
Many devices are programmed to connect automatically to nearby Wi-Fi networks. While this feature is convenient, it can also expose you to security risks. Disable automatic connections and manually select the networks you wish to join. Also, always check with the establishment offering the Wi-Fi which network is theirs. Hackers often copy the names of real Wi-Fi networks to trick people into connecting.
Never access sensitive information
Refrain from checking personal emails, online banking accounts, and other sensitive data when connected to public Wi-Fi. These networks are more vulnerable to attacks, and you increase your risk when you access confidential information while connected to them. If you really must perform sensitive tasks, use your mobile data instead, as it provides a secure, private connection.
Only visit secure websites
When browsing, always look for a little lock in the address bar, which means the website is using hypertext transfer protocol secure (HTTPS) and your information is encrypted. HTTPS scrambles data exchanged between your browser and websites, making it unreadable to anyone else but your device. Consider installing browser extensions that automatically switch websites to the HTTPS version, further ensuring that you're always on a secure page.
Keep your software current
Software updates typically patch security vulnerabilities, so update your software regularly, including your operating system, applications, and browsers. Enable automatic updates on your devices to make sure you never miss installing patches and that your software is running the most recent version.
Forget the network after use
Your device may automatically reconnect to a public network without your knowing, so always delete a public Wi-Fi network when you’re done browsing. This is particularly crucial if you’re in places with numerous public networks, as it minimizes the risk of your devices inadvertently connecting to a potentially malicious hotspot.
