推荐答案
您无法使用默认身份验证删除验证码验证.使用匿名身份验证可以避免出现验证码字母. https://firebase.google.com/docs/auth/web/anonymous-验证
You can't remove captcha verification using default authentication.Use anonymous authentication to avoid captcha letters to appear.https://firebase.google.com/docs/auth/web/anonymous-auth
但是您也可以像这样使它不可见:
But You can also make it invisible like this:
window.recaptchaVerifier = new firebase.auth.RecaptchaVerifier(
"recaptcha-container", {
size: "invisible"
}
);
