Everyday Privacy
Is Public Wi-Fi Safe?
HTTPS made public Wi-Fi far safer than the old horror stories suggest. The real risks now are fake networks and devices left wide open.
What's Actually Risky (and What Isn't)
Almost every site now uses HTTPS, so a stranger on the same network usually cannot read your traffic. The bigger risks today are fake hotspots with names like Free Airport WiFi, fake login pages, and laptops with sharing left on.
Do These on Public Wi-Fi
- Make sure sites show the padlock (HTTPS) before you log in or pay.
- Turn off auto-join, and forget the network when you leave.
- Turn off file sharing and set AirDrop to Contacts Only.
- Keep your firewall on.
When to Use a VPN
- A reputable VPN encrypts everything, useful on networks you do not trust.
- For truly sensitive tasks like banking, your phone's cellular connection is safer than any public Wi-Fi.
Encrypted DNS Helps Everywhere
Even over HTTPS, your DNS lookups can reveal which sites you visit. Encrypted DNS closes that gap on every network you join, see our DNS privacy guide.
Common Questions
Is public Wi-Fi safe for banking?
Use the bank's app over cellular if you can. If you must use Wi-Fi, a VPN plus HTTPS makes it reasonably safe.
Do I really need a VPN?
Not for everyday HTTPS browsing. A VPN matters on untrusted networks or when you want to hide activity from the network owner.
What is an evil twin?
A fake hotspot named to look like the real one. Connect to it and the attacker can serve fake pages. Verify the network name with staff when unsure.
