- 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
