You can add reCAPTCHA to three of your most vulnerable areas.
Adding the new reCAPTCHA is easy and gives you added protection against spam registration attempts and brute force login attempts. To start using reCAPTCHA, from your WordPress dashboard navigate to iThemes Security>Pro Tab and go to the reCAPTCHA section.
After you enable the feature, you will need to get Site and Secret Keys from Google. From your iThemes Security dashboard you can click the blue Google reCAPTCHA link to obtain your keys.
To get the keys needed to activate reCAPTCHA just go to google.com/recaptcha and log in with your Google credentials. Then you will register a new site.
Getting Google reCAPTCHA Keys
To get the keys needed to activate reCAPTCHA just go to google.com/recaptcha and log in with your Google credentials. Then you will register a new site:
After you click the blue Register button, you will see the Site and Secret Key codes that you can copy/paste in the reCAPTCHA section of iThemes Security Pro.
After you’ve pasted in your Keys, you can edit the rest of the reCAPTCHA settings like which pages you want reCAPTCHA to be enforced and how many failed attempts will trigger a lockout and how long iThemes Security needs to remember a failed attempt to count it towards a lockout.
At a minimum, our recommendation is enabling reCAPTCHA on your login and registration pages. This will greatly reduce registration spam and brute force login attempts.
Click “Save All Changes” and you’re set. The next time users log in they will see the new reCAPTCHA field.
Or the next time users comment on your site, they will see this:
