Public Wi-Fi has a scary reputation. Part of it is outdated. Most websites and apps now encrypt traffic, so someone on the same network usually cannot read what you do inside them. Some risks remain.
What is still risky
- Fake networks with a name that looks like the cafe’s. Ask staff for the exact network name.
- Login pages that ask for more than a name or email. A Wi-Fi portal never needs your bank details.
- Ignoring browser warnings about a site’s certificate. If you see one, stop.
What is mostly fine
Reading news, watching video and using apps that show the padlock or use their own encryption is low risk on a public network.
Simple habits
- Keep your phone and apps updated.
- Turn off automatic connection to open networks.
- Use your phone’s hotspot for banking or anything sensitive when you can.
- Turn on two-step verification, so a leaked password is not enough.
- Forget the network when you leave.
What about a VPN?
A VPN hides your traffic from the local network, but it moves trust to the VPN company. It helps on untrusted networks. It does not stop phishing or fix a weak password.
