• Captcha stands for the Completely Automated Public Turing test to tell Computers and Humans Apart
  • Captchas are tools you can use to differentiate between real users and automated users, such as bots
  • Displaying Captcha on login screen, ensure that only humans can log into site. Let’s see how to add captcha in Pega

Steps to Configure Captcha:

  • Open the Security Policies landing page 
  • Configure–>Org & Security–>Authentication–>Security Policies  
  • In the Frequently required policies section, select the “Enable frequently required policies (except for PRAuth-based authentication services)” Check box to enable the frequently required security policies
  • In the CAPTCHA policies section, Select Enabled in “Enable CAPTCHA Reverse Turing test module” to enable the CAPTCHA feature
  • Select Disabled in “Enable presentation of CAPTCHA upon initial login” to ensure that the CAPTCHA appears only after the first failed login attempt
  • Enter 100 in “Probability that CAPTCHA will be presented upon authentication failure (%)” to ensure that the CAPTCHA is always presented when a login attempt fails
  • Submit to apply the security policy updates  
  • When you import security policies in a Pega Platform instance, you may need to clear the “Declare_AuthPolicies”  data page that loads those settings
  • Open “Declare_AuthPolicies” DataPage  
  • Clear data page in Load Management Tab  
  • Logout and Enter Incorrect Password to Login   
  • Captcha will appear
