        Use this option to enable the CAPTCHA to be displayed for every ADManager Plus logon attempt.
      • Show CAPTCHA for invalid logon attempts
        If you select this option, the user will be prompted to specify the  CAPTCHA after failed logons. You can further specify:
        • The number of invalid logon attempts after which the user must be prompted to enter the CAPTCHA.
        • The time limit after which the invalid logon attempts limit must be reset.

      Note: In case you have enabled audio CAPTCHA, only digits will be displayed in the  CAPTCHA. Additionally, if a specific browser does not support audio CAPTCHA,  then the usual CAPTCHA, a combination of alphabets and digits, will be  displayed.
