We don’t have a default social login option, so we utilize 3rd party plugins to have social login functionality. We suggest the following plugins you can try WordPress Social Login or Super Socializer
After the installation and activation of the social login plugin, get the shortcode and use it in Classified Listing => Account & Policy see Social login shortcode inputbox red mark
Add your social login shortcode, which will run at rtcl_login_form hook.
We will support shortcode from any third party plugin.
Example: [TheChamp-Login], [miniorange_social_login theme=”default”]
