Substitute a solution developed in-house
If your team has developed its own CAPTCHA solution, you can use that instead of the default SimpleCaptcha.
Override pyGenerateCustomCaptcha to work with the in-house CAPTCHA solution, following the example for reCAPTCHA, above.You cannot use any other standard activity beside pyGenerateCustomCaptcha with the login screen, as users reaching that screen are not yet authenticated
Invoke pyGenerateCustomCaptcha from pyCustomCaptchaBody, as in the example above
Embed in pyCustomCaptchaHead any scripts the in-house service requires, as in the example above.
Enter appropriate values in pyCustomCaptchaConnector and pyValidateCustomCaptcha.
