HOW TO: add CAPTCHA protection to your WordPress site
Posted by Sugen S. on 06 September 2018 11:54 AM
CAPTCHA is an effective tool that you can use to prevent your contact forms from being used by automated bots, sometimes called spambots, to post spam on your site. CAPTCHA protection works by displaying an image containing text on each contact form. Users need to type the displayed CAPTCHA text before they can submit the form. Because automated bots are unable to read and type the text displayed in the CAPTCHA image, they can’t use your forms to generate spam.
There are two steps you need to complete to add CAPTCHA protection to your WordPress site:
Installing and activating the CAPTCHA plugin
Log in to your WordPress Dashboard as admin. Click Plugins > Add New.
In the Keyword search box, type captcha. Several available CAPTCHA plugins are displayed in the search results. In this example, we’re installing the SI CAPTCHA Anti-Spam plugin. Click Install Now. The Install Now button changes to Installing.
When the installation is complete, the button displays Activate. Click Activate.
The plugin is now active and appears in the Installed Plugins list in your WordPress Dashboard.
Choosing your CAPTCHA settings
Now that the plugin is active, you can choose the types of forms that will be protected by CAPTCHA. You can also change the messages that are displayed with your CAPTCHA.
In your WordPress Dashboard, click Plugins > Installed Plugins > SI Captcha Options.
After you install CAPTCHA, it is automatically enabled on comment, registration, and lost password forms. Because these are the types of forms most often targeted by automated bots, we recommend that you leave these default settings in place.
There are two other default settings that you may want to change:
When you’re finished choosing your form types and making any changes in the Options and Error Messages sections, click Save Changes.
That’s it! CAPTCHA is now protecting your WordPress site from spambots.
