如何在 Firebase Auth 中添加或更新电话号码

Question

I am trying to add a phone number when a user is signing up using Firebase Auth. I am using this method:

user = firebase.auth().createUserWithEmailAndPassword('myemail@email.com', 'password').catch(function(error) {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  // ...
});

And I am trying to update mobile number during the signup process using:

if(user){
  user.updatePhoneNumber("+91999999999")
}

I am getting error:

updatePhoneNumber failed: First argument "phoneCredential" must be a valid phone credential.

I know it needs to be a valid phone number and according to this Answer we need to verify phone number to update.

So my question is I need to create a signup form where I am getting phone email and PWD.

I want to save phone number and verify the number later. Is there any way we can update phone number during signup.

Using this code I can update phone_number in firebase admin:

user = auth.create_user(
    email='user@example.com',
    email_verified=False,
    phone_number='+15555550100',
    password='secretPassword',
    display_name='John Doe',
    photo_url='http://www.example.com/12345678/photo.png',
    disabled=False)

Why there is no function like this in web signup.

Answer 1

There is no way to set a phone number for a user without signing them in with/verifying that number. You will have to sign in the user with phone authentication too, and then link the two providers together .

If you don't want to sign the user in with their phone number, but merely want to store that number, you will have to do so outside of Firebase Authentication's built-in phone number provider.
