From :

If signInWithPhoneNumber results in an error, reset the reCAPTCHA so the user can try again:

grecaptcha.reset(window.recaptchaWidgetId);

// Or, if you haven't stored the widget ID:
window.recaptchaVerifier.render().then(function(widgetId) {
  grecaptcha.reset(widgetId);
}

But grecaptcha is never defined. Do I have to import it from somewhere?

From https://firebase.google./docs/auth/web/phone-auth:

If signInWithPhoneNumber results in an error, reset the reCAPTCHA so the user can try again:

grecaptcha.reset(window.recaptchaWidgetId);

// Or, if you haven't stored the widget ID:
window.recaptchaVerifier.render().then(function(widgetId) {
  grecaptcha.reset(widgetId);
}

But grecaptcha is never defined. Do I have to import it from somewhere?

Looks like it is automatically imported by firebase. However, because I was piling code from ES2015 I needed to add

/* global grecaptcha */

to the top of my js file to make it visible by my code.

The Firebase Auth JS library will pull the grecaptcha library dynamically if it is not already included. Otherwise, if you already include it: https://www.google./recaptcha/api.js, then it will just use that library.
