+The Signal server requires a captcha token for registering a new account.
+If you try registering without one, it normally fails with a captcha required error (`Captcha invalid or required for verification`).
 
-To get the token, go to https://signalcaptchas.org/registration/generate.html
-
-If the token from that page doesn't work, you can try https://signalcaptchas.org/challenge/generate.html
-
-After filling the captcha, the site doesn't show the token but redirects to a `signalcaptcha://` url that contains the token. On mobile devices that url is handled by the apps.
-To see the URL you can open the browser developer tools (F12) before completing the captcha.
-Hint: Enable the option "Persist Logs" in the "Console Settings" to prevent clearing the console each time navigating to a new page.
-
-Check the console in the developer tools for a redirect starting with `signalcaptcha://`
-Everything after `signalcaptcha://` is the captcha token (INCLUDING the `signal-recaptcha-v2.6LfBXs0bAAAAAAjkDyyI1Lk5gBAUWfhI_bIyox5W.registration` part).

-Then execute the `register` command again with the `--captcha` argument (https://github.com/AsamK/signal-cli/blob/master/man/signal-cli.1.adoc#register)
+## Register with captcha token
+When you have the captcha code, execute the `register` command again with the `--captcha` argument (https://github.com/AsamK/signal-cli/blob/master/man/signal-cli.1.adoc#register)
 
 ```
 signal-cli -u USERNAME register --captcha signal-recaptcha...03AG...Uonw
 ```
 
 If you do not get any error, you can proceed with the verify command. If you get the error `Invalid captcha given.`, try to get the captcha again (the captcha is good for a short period of time).
+
+## Get captcha token
+To get the token, go to https://signalcaptchas.org/registration/generate.html
+
+(If the token from that page doesn't work, you can try https://signalcaptchas.org/challenge/generate.html)
+
+After filling the captcha, the site doesn't show the token but redirects to a `signalcaptcha://` url that contains the token.
+
+How to see the captcha token depends on whether one of the official apps (Desktop/iOS/Android) is installed. Because in that case the `signalcaptcha://` url scheme is handled by the apps and the captcha cannot be seen directly.
+
+### No official app installed
+To see the URL you can open the browser developer tools (F12) before completing the captcha.

+
+### Get token from network request
+
+To see the URL you can open the browser developer tools (F12) before completing the captcha and navigate to the network tab.
+The request which includes the captcha token (upon successful completion of the captcha challenge) is a POST with the following path: https://www.google.com/recaptcha/enterprise/userverify. The response includes just the captcha token in the json under key "1". The request includes the 40 character site key for signalcaptchas.org which is 6LfBXs0bAAAAAAjkDyyI1Lk5gBAUWfhI_bIyox5W. See screenshots below.
+
+To get a complete captcha token, prepend `signal-recaptcha-v2.6LfBXs0bAAAAAAjkDyyI1Lk5gBAUWfhI_bIyox5W.registration.` to the token from the request (`03AG...motOQ`)
