I have a client looking to have reCaptcha in their Admin Login module, ideally using the Joomla plugin parameters. Is this something you could add, so that I don't have to switch to a different extension?
I don't plan to add a recaptca challenge into admin area; it's not an effective security measure (almost all bots can defeat it easily). An .htpasswd protection, admin redirection without a valid key and 2FA are the best options to protect your backend.
