I am developing Android app using Firebase. Because of that, I want to use Firebase Auth. I have following requirements:
Register/Log in using Facebook
Register/Log in using Email/Password
Register/Log in using Phone Number/Password
The first two are OK, I followed basic tutorials. However, Phone Number / Password is the problem here. Firebase supports only Phone Number/SMS Token for this (its called Phone Auth), but there is no mention about my case. I do not want to hack Firebase and use its realtime database instead of Auth 'database'. Is there any better way to achieve this?
Thank you.
If you have both email and phone of your user and you can use Admin SDK, then perhaps you could exchange users phone number to his email and login with email and password in the background.
Something like this (node.js)
admin.auth().getUserByPhoneNumber(phoneNumber)
.then(user => {
firebase.auth().signInWithEmailAndPassword(user.email, password);
});
Firebase phone authentication is using OTP(one time password). This way there is no hassle for the user to remember the password. Once authenticated, you will be registered. The sms code acts as a password. But that is for one time. Usually , users prefer such behaviour in which you dont have to remember the passwords. If you are still looking for the way you want, see this link and create a custom authentication method.

I had a similar problem -
I combined firebase auth(email + password) with (phone+otp) to get phone+password auth -

Use Fake Email:
Well, Firebase doesn't support sign in with mobile number and password but it supports email and password. So you can create a fake email with your mobile number.
Ie: 78******69#yourdomain.com
Also, you can create a complete Authentication system using it.
Registration:
Input user mobile and password and proceed to the next page.
Now use Firebase Phone Auth (OTP) to createUser. If process success, link fake email, password credentials in background.
AuthCredential credential = EmailAuthProvider.getCredential(email, password);
auth.getCurrentUser().linkWithCredential(credential);
Login:
Input mobile and password to login. Convert the mobile in fake email and then signInWithEmailAndPassword().
Forget Password:
Redirect the user to a new Page and user Phone Auth to verify the user. If successful, input a new password and change the password of the Email Auth.

I am creating a simple app with login and forgot password using email OTP feature.
I experienced a problem where I cannot login using an account that I recently changed the password using a "Forgot Password" function. I think that the "Forgot Password" function is correct as it correctly changes the password based on my Firebase database. But whenever I use the account that I changed the password, I cannot login to the user even if the credentials are correct. Whenever I use a user account that does not have used the forgot password, the user is successfully logged in.
This is my code. I don't know why the system calls the "else" statement rather than the "if" even if user credentials are correct.
Login Code
Hope anyone can help. Thanks!
i think you have to use VerifyCode (opt) function: FirebaseAuth.Instance.VerifyPasswordResetCode
and make sure email is verified
FirebaseAuth.Instance.CurrentUser.IsEmailVerified
Initially I was having phone OTP verification method to login into my application, later i have added Email / Password method to access the application. How do i merge or link or connect initial phone verified account data to new Email / Password account for the same user?
I want to access same user account by Phone verification and Email / password authentication in firebase realtime database. Is it possible to do?
My firebase structure is like:
- users
-uid
-name: "sam"
-contact: 9999900000
-age: 22
- books
-uid
-bookid
-bookname: "FOCUS"
-price: 355
I should be able to access same uid instead of creating new one by different sign in method. Please help me to do this.
And i also want to avoid everytime login using phone verification, want just by using email password method. phone should not be mandatory
My app have two user( buyer and seller).
I am tring to get current user email which is buyers but when i run the below code, it shows previously logged in user email which is the seller's one.
String userID= FirebaseAuth.getInstance().getCurrentUser().getEmail();
How to write firebase code to get current active user email.
Use this code snippet FirebaseAuth.getInstance().signOut(); to sign out the current user properly, after successfully signed out you can repopulate your user model from Firebase Auth/login in new user. Hope your problem will be solved with this.
When you go to the Auth > Sign-In Methods page of your project in the Firebase console. do you have One account per email address on or off? If you allow multiple accounts per email address, you will get null for FirebaseUser.getEmail()
I create a Firebase Auth user with an email and password
User logs in
User decides to add a phone number to their profile
I call verifyPhoneNumber with an intent to receive a code, call PhoneAuthProvider.getCredential(...) and link resulting AuthCredential to the email and password.
Instead, Android auto retrieves the code, user automatically sign-ins with phone number, their UID changes (it's a new user) and there's no way to link phone credentials back to the original email/password user. To perform a successful link I need to see the SMS code, which is nowhere to be found in case of successful auto sign-in.
????
NO PROFIT.
Any ideas? I tried to set the timeout to 0 for verifyPhoneNumber but auto login still works. Accepting defeat and just link EmailAndPassword credentials to phone number instead of vice versa is not an option, because it will require a massive copying of data from old user record into new, changing all references to this UID everywhere, etc.
verifyPhoneNumber resolves with a PhoneAuthCredential.
It doesn't matter whether the code is auto-retrieved or instant validation occurs. A PhoneAuthCredential is outputted on verifyPhoneNumber completion.
That credential can either be used to signInWithCredential for sign-in or to link to an existing user via linkWithCredential.
If I install an app on Google Play I notice that it informs me about what permissions the app requires. Once it does it in the app it also prompts me. This is all very fine.
I would like to just read the Google or Apple account e-mail - without prompting the end user for an e-mail.
I don't want to use the email as an auth token, but prefill a "Subscribe to News Letter" field. The user can then toggle ON or OFF (or choose to add another email).
If I'm getting the question right,
You need to get the primary email address of the currently signed in user, which can be used to pre-fill some kind of a form (eg. sign-up form)
For Android
Try the following react native wrapper library react-native-account-manager
Once you have setup using the instructions on the readme from the above link, use the following code to retrieve the list of signed in google accounts.
Please note this could result in an empty list, if there are no google accounts associated with the device
import AccountManager from 'react-native-account-manager';
AccountManager.getAccountsByType('accountName').then((accounts) => {
// console.log('available accounts', accounts);
let [firstAccount] = accounts;
AccountManager.getUserData(firstAccount, 'storedKey').then((storedData) => {
// console.log('stored data for storeKey', storedData);
AccountManager.setUserData(account, 'storedKey', JSON.stringify({foo: "bar"})).then(() => {
// console.log('data successfully stored');
})
});
})
For iOS
Bad luck
Apple does NOT expose the iPhone user’s details like their email address, password or credit card details to the app developer.
An alternative is to use the icloud token to create the user. You could use the following guide to do it
For a wrapper on obtaining a iCloud token using react-native use react-native-icloud-user-tokenlibrary
