Firebase 网站。 没有 signInWithUsernameAndPassword 功能

Question

I am very confused about firebase web because when I create an auth using firebase.auth() then try to call a method directly from the firebase documentation, signInWithUsernameAndPassword, it does not work. I am using webstorm and is says it is an unrecognized method.

// Initialize Firebase
var config = {
    apiKey: "AIzaSyBbmdeersid6XSA4kh_TYsGgVSgVF5BrFs",
    authDomain: "eraticators-73723.firebaseapp.com",
    databaseURL: "https://eraticators-73723.firebaseio.com",
    projectId: "eraticators-73723",
    storageBucket: "eraticators-73723.appspot.com",
    messagingSenderId: "782651564720"
};
firebase.initializeApp(config);

const txtEmail = document.getElementById("user");
const txtPassword = document.getElementById("password");
const btnLogin = document.getElementById("btnLogin");

btnLogin.addEventListener("click", function() {
    const email = txtEmail.value;
    const pass = txtPassword.value;
    const auth = firebase.auth();

    firebase.auth().signInWithUsernameAndPassword(email, pass);

});

that is my javascript file. The only suggested functions are signInViaPopup() and signInViaRedirect(). Why is there not signInWithUsernameAndPassword function when that is exactly what the documentation says to use????

Answer 1

signInWithUsernameAndPassword does not exist. Firebase Auth does not support sign in with username and password. It only supports sign in with email and password. The equivalent method is signInWithEmailAndPassword . The Firebase docs and references should not mention the former at all.

Answer 2

can you please check have you enabled authentication with Email/Password. if you didn't enable it. Follow the path given below:-

firebase console -> authentication -> sign-in method.

and enable signIn with email/password

Answer 3

您需要在 html 中添加 script auth 标签。
