01 / Understand
What is happening?
An airport, café or hotel network is a connection you do not control. A fake hotspot, a deceptive captive portal or an outdated device can create risk. Confirm the network name with the venue and do not install a certificate or unfamiliar software just to connect.
Modern HTTPS encrypts the connection between your browser and the website, reducing the risk of someone on the same network reading that traffic. It does not prove a site is legitimate or hide everything about your connection. If you are unsure about a network, using your mobile data is a simple alternative.

Your free first steps
- 01
Confirm the hotspot before connecting.
Ask the venue for the correct network name. Disable automatic connection to unfamiliar networks and forget public networks when you no longer need them.
- 02
Respect browser security warnings.
Use HTTPS websites and keep your browser and operating system updated. Do not bypass certificate warnings or enter sensitive information on an unexpected login page.
- 03
Turn off sharing you do not need.
Use your device’s public-network setting where available. Disable file sharing, unnecessary discovery and automatic joining. Keep multifactor authentication on important accounts.
- 04
Switch connections when uncertain.
Use your phone’s mobile data or personal hotspot for a task that cannot wait. Consider a VPN if you have a clear connection-privacy need, not as a replacement for safe sign-ins.
FTC public Wi-Fi guidance
An important reality check
What tools cannot promise
A VPN encrypts traffic between your device and the VPN provider, shifting some trust to that provider. It does not prevent phishing, remove malware or guarantee anonymity. HTTPS already reduces many public Wi-Fi risks, and a paid VPN is not automatically necessary.
03 / Common questions
A few things worth knowing
Is every public Wi-Fi network unsafe?
No. HTTPS reduces the risk of someone on the same network reading your website traffic. Still verify the network, keep your device updated and avoid bypassing security warnings. Mobile data is an alternative when you do not trust a hotspot.
Do I always need a VPN on public Wi-Fi?
No. The need depends on your connection-privacy goals and the network. HTTPS already protects the content of many website connections. A VPN adds a layer but requires trust in its provider and does not replace safe browsing habits.
Does a VPN make me anonymous?
No. Signed-in accounts, cookies, device information and the VPN provider itself can still identify or link activity. A VPN also does not stop phishing or make an unsafe website legitimate.
