Keeping Children Safe on Public Wi-Fi
What parents need to know about the risks of public Wi-Fi and how to protect children when connecting outside the home.
Overview
Libraries, cafes, shopping centres, hotels, and public transport all offer free Wi-Fi. While convenient, these networks lack the protections you have configured at home. Your DNS filtering, content blocks, and internet schedules do not apply on public networks. This guide helps you understand the risks and keep your child safe when using Wi-Fi outside your home.
Why Public Wi-Fi Is Riskier
Public Wi-Fi networks are shared with strangers and are often unencrypted, meaning data sent over them can potentially be intercepted. More importantly for families, these networks do not have your home parental controls in place. Your child could access content that would normally be blocked, and their browsing activity is not filtered or monitored by your home systems.
Public Wi-Fi bypasses all your home network protections — your child has unrestricted access unless device-level controls are active.
Device-Level Protections That Travel
The most reliable way to protect your child on public Wi-Fi is through device-level controls. iOS Screen Time, Android Family Link, and third-party apps like Qustodio continue to work regardless of which network the device is connected to. Ensure these are properly configured before your child uses any public network. Web content filters, app restrictions, and communication limits should all be active.
Device-level controls are your main defence on public Wi-Fi — they work on any network, not just your home one.
Teaching Children About Public Wi-Fi Risks
Explain to your child that public Wi-Fi is like a public noticeboard — other people might be able to see what you are doing. Teach them never to enter passwords, bank details, or personal information while connected to a public network. If they need to log in to something important, they should wait until they are on a trusted network or use mobile data.
Teach children to avoid entering personal information or passwords on public Wi-Fi networks.
Using a VPN for Family Devices
A Virtual Private Network (VPN) encrypts your internet connection, making it much harder for anyone on the same public network to see your activity. Some family-oriented VPN services also include content filtering. If your child regularly uses public Wi-Fi — for example, at a library for homework — a VPN is worth considering. Set it to connect automatically on untrusted networks.
A VPN encrypts your child's connection on public Wi-Fi — consider one if they regularly use networks outside the home.
