Enable DNN captcha

Captcha : In simple terms it is a Server Control that requires the "user" to enter a randomly generated  "Human Readable Security Code". Something like below:

To enable captcha for dnn login/registration page for dnn 4.8.1 and newer version, you need to do the following:

Login admin->user accounts->user settings, at the bottom check the box "Use CAPTCHA For Login" and "Use CAPTCHA For registration". This just be able to enable user registration page not the login page.

To enable the login page using captcha, go to admin->authentication->check the box "Use Captcha?" and update, now you’ll see it.

For older version, you just need to do the first step to enable captcha.
