What Is a Wi-Fi Login Page? Hotel and Airport Wi-Fi Sign-In Explained

A Wi-Fi login page, also called a captive portal, is the screen that hotels, airports, cafes and trains show after you join their Wi-Fi and before they let you onto the internet. It usually asks you to accept terms, enter a room number or a code, or watch a short ad.

Checked on 8 November 2026.

How does a Wi-Fi login page work?

A Wi-Fi login page works by holding your connection until you sign in. When you join the network, your iPhone checks whether it can reach the internet. If the network answers with its own page instead, iPhone opens a small sign-in window by itself. Until you finish that page, websites and most apps will not load, even though the Wi-Fi icon shows you are connected.

What is safe to type on a Wi-Fi login page?

It is safe to type what the venue already knows or gave you: a room number and surname, a voucher code from the front desk, or a tick to accept the terms. Be careful with anything more. A real hotel or airport page has no reason to ask for your email password, your Apple Account password or a full card number just to get online. A page that asks for these may be fake, set up by someone running a copy of the network.

Why does my VPN not connect on hotel Wi-Fi?

Your VPN often cannot connect on hotel Wi-Fi until you finish the login page, because the network blocks all traffic, including the VPN, until you sign in. Turn the VPN off for a moment if needed, complete the login page, then turn the VPN back on. Do this before you open email, banking or any other app, so your traffic is encrypted from the first page you load.

How do you sign in to public Wi-Fi safely in 4 steps?

  • Join the exact network name. Check the name with staff or a printed sign, so you do not join a copy.
  • Use only the details the venue gave you. Room number, surname or a printed code. Never a password from another account.
  • Turn the VPN on right after the login page. Once the page says you are connected, switch the VPN on before you browse.
  • Watch for odd requests. If the page asks you to install a profile, certificate or app, close it and ask staff.
  • What if the Wi-Fi login page does not appear on iPhone?

    If the login page does not appear, go to Settings > Wi-Fi, tap the (i) next to the network, and tap Forget This Network, then join again. You can also open Safari and visit a plain address such as captive.apple.com, which makes the network show its page. If a VPN is set to connect on its own, switch it off until the page loads.

    Frequently asked questions

    Is hotel Wi-Fi safe after I sign in?

    Signing in does not encrypt anything. Other guests share the same network, so turn on a VPN after the login page to keep your traffic private.

    Why does the login page come back every day?

    Many hotels and airports sign you out after a set time, often 24 hours, so you have to accept the page again.

    Can I skip the login page?

    No. The network will not pass any traffic until the page is finished, so complete it first and then turn on your VPN.
