The Captcha connector allows SigningHub to connect with Google Captcha to distinguish human from bots and provide foolproof security against spam attacks or automated extraction of data from the system. For this, SigningHub needs to be registered with the Google Captcha platform. 
When configured in the Global Settings, Google Captcha is shown on the following pages of SigningHub:

• Admin Login: Google captcha will be shown if login attempts are failed/ unsuccessful for three consecutive times.
• Desktop Web Login page: Google captcha will be shown if login attempts are failed/ unsuccessful for three consecutive times.
• Desktop Web Activation Dialog: Google captcha will be shown by default.
• Desktop Web Resent Activation Email: Google captcha will be shown by default.
  
• Desktop Web Registration: Google captcha will be shown by default.
• Desktop Web Forgot Password: Google captcha will be shown by default.
