What captive portals are

A captive portal is a web page that is often displayed before you can access the Internet on public networks in airports, hotels, libraries, and other places.

Tails cannot connect to the Tor network when the Internet connection is initially blocked by a captive portal.

The Unsafe Browser is not anonymous

The Unsafe Browser does not use Tor. The websites that you visit can see your real IP address.

This is why we recommend that you:

  • Only use the Unsafe Browser to sign in to a network using a captive portal or browse trusted web pages on the local network.

  • Close the Unsafe Browser after signing in to the network.

    It is particularly important that you close the Unsafe Browser if you use accessibility features like the Screen Keyboard or the Screen Reader. If you keep the Unsafe Browser open, a very advanced network attacker might use it to deanonymize you.

To learn how Tails implements the Unsafe Browser and its security, see our design documentation about the Unsafe Browser.

  2. If you are redirected to a captive portal, sign in to the network.

    If you are not redirected to a captive portal and the website loads, this means that you are already connected to the Internet. Close this browser the Unsafe Browser and try connecting to the Tor network again.

  3. After Tails is connected to Tor, close this browser. the Unsafe Browser.

    It is particularly important that you close the Unsafe Browser if you use accessibility features like the Screen Keyboard or the Screen Reader. If you keep the Unsafe Browser open, a very advanced network attacker might use it to deanonymize you.

    You can use Tor Browser or any other application as usual.
