Is hotel and airport Wi-Fi safe?
Quick answer: It is not automatically dangerous, but you cannot trust a network you do not control. Avoid sensitive logins on it, use HTTPS sites, turn off auto-join, and use a VPN or your own mobile data for banking and work.

The real risks
- Fake networks. An attacker can create a hotspot with a convincing name such as the hotel's or the airport's. Connecting to it hands them your traffic.
- Other people on the same network. On poorly set up networks, other users may see unencrypted traffic or try to attack devices.
- Sign-in pages. Some captive portals ask for your name, email or room number. Give only what is needed.
What to avoid on public Wi-Fi
- Banking and card payments, unless you use a VPN or mobile data
- Logging into work systems without your employer's approved method
- Downloading software or updates from random pop-ups
What to do instead
- Ask staff for the exact network name and password, and do not join similarly named networks.
- Check the site address starts with https:// and the padlock is present.
- Turn off automatic Wi-Fi joining and Bluetooth when you are not using them.
- Use your eSIM or mobile data for banking and anything sensitive.
- If you must use the Wi-Fi for something sensitive, use a VPN. See do you need a VPN abroad.

Frequently asked questions
Is hotel Wi-Fi safer than airport Wi-Fi?
Not reliably. Both are shared networks you do not control. Treat them the same way.
Can I use online banking on hotel Wi-Fi?
It is best to use mobile data or a VPN. Most banking apps use encryption, but you reduce the risk by avoiding untrusted networks.
Does a VPN stop fake Wi-Fi networks?
A VPN encrypts your traffic once connected, but connecting to a fake network is still a bad idea. Confirm the network name with staff first.
