Public Wi-Fi makes it easy to stay connected at coffee shops, airports, hotels, shopping centres and other public places. However, connecting to an unfamiliar network can come with security risks, particularly if the network is fake, compromised or poorly secured.

It is still important to take precautions when connecting to public Wi-Fi. While public networks can be convenient, taking a few simple steps can help reduce your exposure to online threats.

1. Connecting without checking the network

Before connecting to public Wi-Fi, make sure you are joining the legitimate network. Check the official network name with a staff member or look for the network name displayed on official signage at the venue. Avoid connecting to networks with unfamiliar names or those that appear to imitate the legitimate network.

2. Relying on a VPN alone

One way to add an extra layer of privacy when using public Wi-Fi is a virtual private network (VPN). A VPN creates an encrypted connection between your device and the VPN service, helping protect your traffic while using an unfamiliar network. However, a VPN should be used alongside other security measures rather than as a replacement for them.

3. Leaving automatic Wi-Fi connections enabled

Disable automatic Wi-Fi connections so that your device does not connect to networks without you choosing them. This gives you more control over which networks your device joins to and reduces the chance of unintentionally joining an unfamiliar network.

4. Leaving sharing features on

Turn off file sharing, network discovery and similar features when they are not needed. On Apple devices, review your AirDrop settings and choose an appropriate receiving option. These steps reduce the chances of unintentionally exposing your device or files to other people on the network.

5. Carrying out sensitive activities

If you do need to use public Wi-Fi, check that the website uses HTTPS before entering sensitive information. The padlock symbol or “https://” in your browser indicates that the connection between your browser and the website is encrypted, although it does not guarantee that the website itself is legitimate.If you do need to use public Wi-Fi, check that the website uses HTTPS before entering sensitive information.

6. Skipping multi-factor authentication

Enable multi-factor authentication on your accounts wherever it is available. Multi-factor authentication adds another layer of protection by requiring two or more forms of verification before access is granted. This can help protect your accounts even if someone manages to obtain your password.

7. Ignoring software updates

Keep your software up to date by regularly updating your operating system, web browser, apps and security software. Updates often include security fixes that address vulnerabilities discovered after software has been released. Enabling automatic updates can help ensure that important protections are installed promptly.

Public Wi-Fi does not have to be something you avoid completely. The key is to be mindful of which network you connect to, how your device is configured and what you do while connected. By taking these precautions, you can enjoy the convenience of public Wi-Fi while reducing your exposure to online threats. Stay connected, but stay cautious.
