To add or configure third-party captcha providers simply select the “Captcha Providers” tab on the Settings page and then click “Add Source”. Doing this will bring up a pop-up asking you to input the following:
Name: The name you wish to give your provider.
Platform: The third-party platform you wish to integrate.
API Key: The API key from said third-party platform (This varies per provider and you’ll need to refer to their specific documentation to generate or locate your API key).
Concurrency: How many captcha requests you wish to be submitted at any given time – This can either be a number or fully disabled via the toggle to the right hand side.
