Access Manager supports only the invisible reCAPTCHA version of reCAPTCHA. reCAPTCHA works on both Name/Password – Form and Secure Name/Password – Form authentication.
reCAPTCHA provides an additional layer of security by requesting users to confirm that they are not a robot. It displays images that users must select based on a matching criteria. If a response succeeds, Access Manager authenticates the user’s authentication credentials. If a response fails, Access Manager does not authenticate the user credentials, and redirects to the login page.
NOTE:By default, reCAPTCHA is disabled. Before enabling this feature, verify your privacy statement. Some regions may consider it a privacy issue.
