According to studies, there are 500+ million public Wi-Fi hotspots worldwide. With this number growing, experts are concerned about the safety and security of these networks. A 2017 research by Statista showed that 28% logged into their personal e-mail accounts using public Wi-Fi. Another 16% provided their card details using these networks.
These numbers prove that most people are unaware of the potential security risks of public Wi-Fi. Scammers can easily intercept data shared via these networks, leading to the loss of personal information and funds. But you don’t need to stop using public Wi-Fi because there are several tips to ensure your safety.

1: Verify the Public Wi-Fi
Let’s assume you are at the school library with an open network called “School Library.” This may seem like a trusted Wi-Fi network operated by the institution. You can be tempted to connect your device and enjoy the free internet. But how can you confirm that this public Wi-Fi network is actually legit?
The thing is that scammers can set up internet networks in public places. Thankfully, most public places have signs showing the name of the Wi-Fi networks they provide. If unsure, ask someone working at the place if the network is legit. Confirm that the network is legit before clicking “Connect.”
2: Login Using VPN
Enjoying free Wi-Fi on public networks may be an irresistible temptation. But even if the network is legit, there is always a chance that scammers are camping here to steal data. The good news is that you can use a VPN (Virtual Private Network) to mask your IP address. This means scammers won’t be able to access your actual location and track your whereabouts.
Today, you can enjoy safe browsing with a free VPN. If provided by a reliable company, these free services guarantee safe and secure online experiences. However, subscription-based VPN services are generally more reliable. Compare the prices to find the best deals without jeopardizing your online security.
3: Always Forget the Network
After browsing using public Wi-Fi, it’s vital to log out. But don’t stop at that. Proceed to forget or delete the network entirely from your browsing device. For example, if you’re using a Windows PC, open the Wi-Fi network settings, then choose “Manage known networks.” From there, choose a network, then tap “Forget.”
In addition, adjust your settings to prevent the network from reconnecting automatically. This is especially helpful if you’re a frequent visitor at the same Wi-Fi hotspots. This allows you to confirm the network is safe before reconnecting your device. With public Wi-Fi, it’s always safe to reconnect manually because things can change.
We share many important information online nowadays. For example, if you like gambling online, you can be requested to provide a payment method for deposits and withdrawals. The best online casinos can also request that you provide sensitive information like your ID and bank statement. This is sensitive information that you shouldn’t give anyhow.
The general rule of thumb is to avoid sharing vital information online when using a public Wi-Fi network. Someone could easily intercept your data owing to the open nature of these networks. So, only use public Wi-Fi for general browsing purposes. Don’t share anything, even if the website is fully encrypted.
5: Disable File Sharing
Another tip is to turn off file sharing on your computer before connecting it to a public Wi-Fi network. Keeping this feature on means everyone on the network can access your local files and folders. Of course, this includes hackers and scammers who won’t hesitate to steal your private data.
The good news is that you can easily turn off this feature and enjoy safe browsing. You can achieve that with Windows PCs by merely selecting “Public” when connecting to a Wi-Fi network for the first time. On Mac, click System Preferences > Sharing and then unselect everything. Now, make yourself undiscoverable from anyone on AirDrop.
6: Only Visit Encrypted Websites
This should be your last line of defence when using an unknown public Wi-Fi. Website links that start with a lock icon and “https” are generally encrypted. These websites use SSL and TSL encryption protocols to protect communications and transactions. In short, it’s a protection wall that stops cyberattacks right in their tracks.
Below are some tips to help you confirm if a website is encrypted:
- Confirm if the website address starts with “https” instead of “http.”
- A padlock sign on the URL.
- Click the padlock sign to confirm if the certificate is updated.
- Websites operated by unknown entities or individuals.
7: Update Your Operating System
Regularly updating your computer or smartphone operating system has many advantages. New software updates come with improved security patches that could protect you from public Wi-Fi attacks. Operating systems, like any software, are prone to bugs and security flaws. Therefore, upgrading the software will fix these issues and lock out malicious actors. Don’t forget to update your apps, especially browsers, regularly.
Here are other advantages of updating your OS and apps:
- New and refreshing user interfaces.
- Increased performance stability and effectiveness.
- Improved compatibility with the latest devices and apps.
8: Consider Using Phone Hotspot
Connecting to public Wi-Fi networks still carries immense risks even with the aforementioned precautions. The best solution might be to avoid those networks altogether. But there is a secure and more convenient alternative in your smartphone’s hotspot. Nearly all modern smartphones can act as Wi-Fi hotspots for connecting numerous devices. Just turn on your data and connect it to your PC as Wi-Fi.
USB tethering is another secure way to share a smartphone network with your PC. Instead of connecting your computer directly to the public Wi-Fi, use a USB network to share your phone’s network connection. Mobile operating systems are inherently safer than PC systems when it comes to virus and malware attacks.
Conclusion
There is no guarantee that you will face security risks when using public Wi-Fi. However, don’t let your guard down with these risky networks by applying the tips above. Remember that any public Wi-Fi without a unique password is dangerous to use. But most importantly, don’t share sensitive information online using public Wi-Fi. Browse safely!
