At the airport Dan joins the Wi-Fi and a page opens: “Sign in with Google to get internet”. What should he do?

Don’t enter the password, disconnect and use his phone’s hotspot. An account password on a Wi-Fi page is the classic fake-network trap.

What does a VPN actually protect against?

The network owner seeing where you go. A VPN hides traffic from the network you’re on, and that’s it.

Which router step matters most?

Change the admin password and turn on updates. Default passwords and old firmware are what mass attacks exploit.

Wi-Fi, VPN and your router

Lesson 15 of 16 in the course “Cybersecurity from Scratch”. Free, with animations and a quiz.

Café horror stories are outdated

Public Wi-Fi really did let people snoop passwords once. Today almost every site and app encrypts the connection itself; that’s the padlock and HTTPS in the address bar. The real danger is different: a fake network with a similar name that shows a “login page” asking for your email or social media login. Rule: never type your account passwords on a Wi-Fi sign-in page.

A VPN isn’t a shield against everything

A VPN is a tunnel: your traffic goes first to the VPN company’s server and only then to the internet. The café network owner sees nothing, but the VPN company sees everything. It doesn’t protect against phishing, stealers or weak passwords at all. So choose a paid service with a clear reputation, not a free one that earns money from your data. And don’t treat a VPN as a replacement for 2FA and updates.

The router is your home’s front door

All your home internet goes through the router, yet many people live for years with an admin password like admin/admin. Open its settings; the address is usually on the sticker underneath. Change the admin password, turn on auto-updates, pick WPA3 or WPA2 and turn off WPS, the push-button connect feature that’s easy to brute-force. Put smart bulbs and cameras on the guest network: if they get hacked, the attacker can’t reach your laptop.
