The honest answer is: mostly yes, with a few caveats. Public Wi-Fi at a cafe, mall or airport is fine for everyday browsing, but there are specific risks worth understanding.
What has improved
Most websites and apps now use HTTPS, which encrypts the content of what you send and receive. That means someone on the same network generally can't read your messages or see your passwords on a properly secured site. This has made casual snooping far harder than it used to be.
What can still go wrong
- Fake hotspots. Someone can set up a network named like the venue's ("Cafe_Guest_Free"). If you join it, they control the connection you're using.
- Open, unencrypted networks. If the network has no password, traffic between your device and the router isn't protected at the Wi-Fi level.
- Visible metadata. Even with HTTPS, the network can often see which domains you connect to.
- Sign-in pages. Some networks ask for your name, number or email. That's data you're handing over, so share only what you're comfortable with.
- Outdated devices. Unpatched software is a bigger risk on any shared network.
Simple habits that help
- Ask staff for the exact network name before joining.
- Keep your phone and laptop updated.
- Look for the padlock and HTTPS on sites where you sign in.
- Turn off automatic joining of open networks.
- For banking or anything sensitive, consider using mobile data instead.
- Use a VPN to encrypt your traffic between your device and the VPN server, so others on the network can't read it.
You don't need to avoid public Wi-Fi. A few good habits, and optionally a VPN, take care of most of the risk.

Comfortable on any network
A VPN adds encryption on networks you don't control. Anchored Privacy keeps it simple.
