Free internet at the library, café or shopping centre is handy when you want to check the news, video call the grandkids or look up a bus timetable. But is public wi-fi safe? The short answer is that it can be fine for casual use, as long as you know the risks and take a few sensible precautions.
Why public Wi-Fi can be risky
Public wi-fi is shared by everyone nearby, and many networks are not well protected. This means a determined scammer may be able to see what you are doing online or set up a fake network with a believable name, such as a café name followed by the word free. If you connect to the wrong one, your personal details could be at risk. Online scams are common in New Zealand, so it pays to stay alert.
What is fine to do
Reading the news, checking the weather, browsing recipes or watching a video is generally low risk on public wi-fi. These activities do not involve personal details, so there is little for anyone to take.
What to avoid
Try to avoid online banking, paying bills or entering your card details while connected to public wi-fi. It is also wise to hold off on logging in to important accounts, such as your email or RealMe. Save those jobs for your home network or your mobile data, which is usually safer.
Simple ways to stay safer
Always ask staff for the correct network name before you connect. Turn off automatic connection to open networks in your phone or tablet settings, and choose to forget the network when you leave. Keep your device updated, because updates often fix security problems. Look for the padlock symbol next to a website address, which shows the connection is protected. Strong, unique passwords and two-step login add another layer of protection, and a trusted virtual private network, often called a VPN, can help too.
Where to get help
If something does not feel right, or you think you have been scammed, contact your bank straight away. Netsafe, New Zealand’s online safety organisation, offers free advice. Family members or your local SeniorNet can also help you set up your devices safely.
