Why break your valuable mobile data usage when you can hop on the site for free? But here’s the deal: Security personnel especially those in the Internet security also use some other names to describe this same public Wi-Fi connection as highly insecure. Don’t worry, though!

Here are the things which make the public Wi-Fi dangerous and how one can use them correct.

The Not-So-Pretty Side of Public Wi-Fi

Well, let us break it down: What makes using public access Wi-Fi dangerous in the first place? Picture this: you are in the middle of a café drinking coffee with your friends and simultaneously liking posts on social media. But you are just one among dozens of users in that network and many of them are potentially dangerous and can breach your security. Usually, Public Wi-Fi networks are “Open” that is the data sent through these networks is not secure. If somebody wanted to, he or she could easily Monday morning quarterback, if the person has the know-how, he or she could easily intercept the information. Scary, right?

Protecting Yourself on Public Wi-Fi: Your Toolkit

You don’t have to avoid public Wi-Fi entirely; you just need to be smart about it. Here are a few straightforward tips to keep your information safe while still enjoying the perks of free internet.

Get a VPN: A VPN (known as Virtual Private Network) is like a invisibility cloak for your online stuff, keeping your browsing private and secure. It encrypts your data, making it virtually impossible for someone to read, even if they manage to intercept it. A VPN is your go-to shield when you’re connecting to any network you don’t fully trust. There are plenty of options out there, and yes, some come free. Just remember, the stronger the VPN, the better the protection.
Stick to HTTPS Sites: Did you ever noticed that little padlock icon in your browser? That’s HTTPS—a secure version of HTTP. Which is the standard protocol for websites. It’s like adding an extra lock on your door. When you see HTTPS, it means the communication data between your browser and the website server is encrypted. Making it a safer bet than HTTP-only sites. So, if you’re on public Wi-Fi, only enter sensitive information on sites that show that little padlock.
Turn Off Auto-Connect: Some devices have this convenient but slightly dangerous setting that automatically connects you to any nearby Wi-Fi network. Imagine walking down a street and being automatically connected to every café, shop, and hotspot. Yeah, it’s not ideal. Take a moment to disable auto-connect in your settings so you can decide when and where you connect.
Avoid Sensitive Transactions: Sure, public Wi-Fi is fine for a bit of social media scrolling or reading the news, but maybe save the online banking and shopping for when you’re on a secure network. If you wouldn’t shout your credit card details across a room, don’t type them in on an unsecured network, either.
Use Two-Factor Authentication (2FA): Even if a hacker manages to get your password, 2FA can add an extra hurdle. By requiring an extra verification, like a code sent to your phone, 2FA can keep your sensitive accounts locked tight.

Pros and Cons of Public Wi-Fi

You don’t need to log into anything too sensitive, but you do want to avoid prying eyes. This is the perfect time to activate your VPN. Also, check that any site you’re using has HTTPS, just in case.

Or maybe you’re working remotely from a coffee shop. With your auto-connect feature off, you connect to their Wi-Fi only when you’re ready. You’ve set up 2FA on your work accounts, so even if someone tries to access your data, they’re going to hit a wall.
