The official ATL WiFi network

Source (official airport page): Hartsfield-Jackson Atlanta International Airport

What the sign-in page should ask for

ATL’s sign-in asks you to fill out the required information and accept the Terms of Use. Give only what the form needs; a name or email is normal, a card number or your email password never is. The airport also notes that corporate VPNs work on the network.

Rule of thumb for any airport: a WiFi sign-in page may ask you to accept terms, watch an ad or enter basic contact details. It should never ask for a card number, your email password or a bank login.

Lookalike networks

The airport publishes ATL Free Wi-Fi. ATL-WiFi, Atlanta Airport Free or Hartsfield WiFi are not on the official page.

Copycat networks (“evil twins”) work by broadcasting a name that looks trusted, sometimes with a stronger signal than the real one. CISA advises confirming the name of a public hotspot before you use it, so if two similar names appear, ask staff or check the airport’s website.

A 5-step check at ATL

1. Join exactly ATL Free Wi-Fi — not a similar name, and not one that appeared after you arrived at the gate.
2. Complete the sign-in page and look at its address: the airport or its WiFi provider, ideally over HTTPS.
3. Use apps and sites over HTTPS. If a site you know suddenly shows a certificate warning, stop.
4. Keep banking and work logins for a network you have checked, or use mobile data or your company VPN.
5. Turn off Auto-Join for this network before you leave, so your phone doesn’t silently rejoin a lookalike later.
