Captchas

Sometimes Signal requires a completion of a captcha to register. When this happens, signald throws a CaptchaRequiredException error. If that error is thrown the user must complete a captcha.

Getting A Token

Either use the captcha helper utility or follow these steps in your browser:

  1. Go to https://signalcaptchas.org/registration/generate.html
  2. Do whatever is needed to pass the captcha. You need to be able to load a Google captcha, which may require disabling some content filtering. Try using a private browsing window if you get a blank screen.
  3. You will be redirected to a URL that your browser won’t understand, starting with signalcaptcha://. Everything after signalcaptcha:// is the captcha token, copy it. In Firefox, you may need to open the Developer Console (Menu -> Web Developer -> Console or ctrl-shift-k), where the signalcaptcha:// URL will show up as part of a warning message.

Register With A Token

Most users will simply need to provide the captcha token to their client. Client authors should simply include the captcha token in a registration request.
