Choose between the captcha, an invisible textbox or a minimum form submission time to prevent automated form submissions.
Enable your captcha control to be read via a generated audio code, ideal in accessibility situations.
Display your captcha errors in your existing validation summary control.
Custom Character Set
Define which character set the captcha control will derive its image from.
Localization and Accessibility
Provide a captcha interface for all of your users—regardless of preferred language. Thanks to the localization mechanism, based off of ASP.NET localization, you can serve the control in any language you have defined for your application.
