Three new controls hit the toolbox. The first is Captcha, this control request the user to enter a (n) of characters to continue. The second is the International Tel number control. This control is a telephone input with a dropdown country code selector. The third is reCAPTCHA, this requires a key to be set up in your appsettings.config file. The reCAPTCHA is v2 so displays a checkbox "I am not a Robot"
