Recaptcha blocks access to my WordPress editor

Solution:1

Log into your Cpanel or FTP. Look for the directory /public_html/wp-content/plugins and rename the reCAPTCHA plugin folder. For example rename “uber-norecaptcha” to “uber-norecaptcha123”. Refresh your WP-admin url. Now you can log in. Don’t forget to rename the reCaptcha to it original, then you can deactivate it when you’re logged in.

Solution:2

You could try to disable the plugin that added the reCAPTCHA (in this case, Contact Form 7), so you can login again. Then, you can re-enable it and set your site and secret keys properly.

Since you are unable to login, you can’t disable the plugin from the WordPress dashboard. Instead you can temporarily move the plugin folder to another location. Navigate to the folder of your WordPress installation → wp-content → plugins and move the contact-form-7 folder.
