    Hi @Shahid Nabi (CONVERGYS CORPORATION),

    Thank you for posting in this community.

    According to the official Microsoft documentation for SharePoint, we can only find information about authentication for SharePoint Server and not for web applications.

    Perhaps you could seek out other three-party tools that enable you to add Captcha to web applications.

    Thank you for your kind understanding.
