I do not believe a captcha on the login control is available anymore through the core of DNN, you would want to look at a third party authentication provider to support that. If you look at the settings for adding a captcha it is only for associating logins, password reset, registration, or change password.

Hi Justin 

Thank you for getting back to me. I have another website where I've added a CAPTCHA to the login page. However, this website was initially built using an older version of DNN (DotNetNuke) and has been recently updated to DNN 9.11. I'm wondering if there's a way to make the CAPTCHA show up on the login page, either by making changes to the database or by modifying the code.

I have found solution for that we can enable CAPTCHA in login page fallowing these steps

In the newer version of DNN, the option to add CAPTCHA to the login page isn't readily available. However, there's a workaround you can implement by following these steps:

1. Access PortalSettings: Navigate to your DNN installation and locate the PortalSettings.

2. Add or Locate "DNN_UseCaptcha": If you can't find the "DNN_UseCaptcha" setting, add it to the PortalSettings.

3. Activate CAPTCHA: Modify the "DNN_UseCaptcha" SettingValue to "True." This action activates the CAPTCHA feature for your login page.

4. Clear Website Cache: After making this change, clear your website's cache to ensure the newly applied settings take effect.

5. Restart Application: To finalize the process, restart your application via the admin settings.

By following these steps, you'll successfully enable the CAPTCHA feature on your DNN website's login page, even after updating to the newer version. This added security measure helps protect your website against unwanted access.

Awesome Ravindu! Thanks for sharing your workaround.

Hey!  I just added a set-captcha command to Upendo DNN Prompt for you.  This way, it'll be easier to turn this on/off next time.  ;)

I followed the steps diligently and am pleased to report that I successfully enabled CAPTCHA on my DNN website's login page.

 

 

The setting is still in DNN but not in site settings but under Security.
But when activated, nothing happens. Added the workaround to https://github.com/dnnsof...Platform/issues/4409 in order to prove that people still want this :-)
