firebase：如何链接电子邮件验证和密码

Question

I already authenticate user with email and password, but I want to add email link verification using firebase in react native.

So, user have to provide right email address that he/she owned and password, how can I link them or create it.

This is my code for signup:

export const signupUser = ({firstName, lastName, userName, email, password}) => async dispatch => {
    dispatch({ type: SIGNUP_SPINNER });
    try {
        let user = await firebase.auth().createUserWithEmailAndPassword(email, password);
        if(user) {
            const { currentUser } = firebase.auth();
            // add displayName 
            await currentUser.updateProfile({
                displayName: `${firstName} ${lastName}`
            });
            await firebase.database().ref(`/users/${currentUser.uid}/profile`)
                .push({firstName, lastName, userName, email})
                .then(async () => {
                    dispatch({ type: SIGNUP_INITIAL_STATE });
                });
        }
    } catch(err) {
        dispatch({ type: SIGNUP_USER_FAIL, payload: 'something went wrong, please try again!!!' });
    }
}

The email verification could be done in several ways in mobile apps:

1. let user to login via native account attached to the phone ( https://github.com/react-native-community/react-native-google-signin ). If user able to login via google means that he's a legal user of the account
2. Send email ( Sending automated emails from Firebase through Google Cloud Platform (no third parties) ) with link like https://yourserver.com/?token= and activate the email if user opens this link. In this case you need your own script on the server.
3. Send email ( Sending automated emails from Firebase through Google Cloud Platform (no third parties) ) with link like yourScheme://verification?token and handle this scheme on your device and veridy the account by endpoint. It's less secure but you don't need your server.
