Pega Platform provides CAPTCHA validation on login as one of the options on the Security Policies landing page. A CAPTCHA (or Reverse Turing Test) creates a challenge that is easy enough for a human user to meet, but which is likely to defeat standard automated software.
For most implementations the default CAPTCHA provided in Pega Platform will provide satisfactory service. However, if you already use another CAPTCHA service (perhaps one your team has developed) in other applications, and would prefer to deploy it for PRPC, you can do so following the steps below. You can also adjust the display of the default CAPTCHA to better match the need of both system security and valid users who wish to log in.
To use any of the options below, you need to create a ruleset and an access group to serve unauthenticated visitors to the site. You use the same ruleset for CAPTCHA refinements and for updates to the images on the login screen.
