Authenticate on Firebase with phone number

I have gone though the doc of Firebase, and it seems that we need to provide an email to authenticate a user.

However I rely on phone number.

Is there a way to do this ?

Firebase is now supporting auth with Phone number: https://firebase.google.com/docs/auth/web/phone-auth

UPDATE: The link is for the official doku so pleas read there all instructions because.

I would recommend to use the firebaseui library that does all the auth UI stuff for you. Here is the web version: https://github.com/firebase/firebaseui-web There are also some for the Android and iOS projects.

Here is also a demo application you can use to start your own one: https://github.com/TarikHuber/react-most-wanted

It has also a running demo: https://www.react-most-wanted.com/ You can there try out all of the auth methods.

The actual implementation is pretty simple if you use the firebaseui. Here is mine in a React Component.

import React, {Component} from 'react';
import PropTypes from 'prop-types';
import { connect } from 'react-redux';
import {injectIntl} from 'react-intl';
import { Activity } from '../../components/Activity';
import muiThemeable from 'material-ui/styles/muiThemeable';
import { push } from 'react-router-redux';
import firebase from 'firebase';
import firebaseui from 'firebaseui';
import {firebaseAuth} from '../../utils/firebase';

var authUi = new firebaseui.auth.AuthUI(firebaseAuth);

class SignIn extends Component {

  componentDidMount() {
    const {router, browser}= this.props;

    const redirect =((router || {}).location || {}).search;

    var uiConfig = {
      signInSuccessUrl: redirect.slice(1),
      signInFlow: browser.greaterThan.medium?'popup':'redirect',
      callbacks: {
        signInSuccess: function(user, credentials, redirect) {

          push(redirect || '/');

          //To avoid page reload on single page applications
          return false;
        }
      },
      signInOptions: [
        firebase.auth.GoogleAuthProvider.PROVIDER_ID,
        firebase.auth.FacebookAuthProvider.PROVIDER_ID,
        firebase.auth.TwitterAuthProvider.PROVIDER_ID,
        firebase.auth.GithubAuthProvider.PROVIDER_ID,
        firebase.auth.EmailAuthProvider.PROVIDER_ID,
        firebase.auth.PhoneAuthProvider.PROVIDER_ID
      ]
    };

    authUi.start('#firebaseui-auth', uiConfig);
    
  }

  componentWillUnmount() {
    authUi.reset();
  }

  render(){

    const  {intl} = this.props;

    return (
      <Activity
        title={intl.formatMessage({id: 'sign_in'})}>
        <div style={{paddingTop: 35, width: '100%'}}>
          <div id="firebaseui-auth" style={{width: '100%'}}></div>
        </div>
      </Activity>
    );

  }

}


SignIn.propTypes = {
  push: PropTypes.func.isRequired,
  intl: PropTypes.object.isRequired,
  router: PropTypes.object.isRequired,
  muiTheme: PropTypes.object.isRequired,
};


const mapStateToProps = (state) => {
  const {router, browser } = state;
  return {
    router,
    browser
  };
};


export default connect(
  mapStateToProps,
  { push}
)(injectIntl(muiThemeable()(SignIn)));

My usecase is different. I have to allow my users to perform login via mail and phone number both. Here how I am doing it:

Store emailId and phone number separately in Firebase Database.

Now for login via email and password:

  1. Using inbuilt method of signInWithEmailAndpassword

For login via phone no and password:

  1. Fetch Email id of user from Firebase database by passing user provided phone no
  2. If no email id returns, show error that phone no is not mapped to any account or account doesn't exist
  3. Once you receive email id, call signInWithEmailAndpassword and pass received email and user provided password

This is just a workaround which I found. I am still able to use reset password feature of Firebase :)

Just came across this question.. you can just add your domain to the end of phone number and still make it a email. [email protected]. Make sure to add this for signup and login. This is what im doing. The only downside of this approachis that you can't use firebase's provided functionality to send password reset emails to users. You have to implement your own service service to provide that.
