I want to create auth0 new users from admin panel. Currently, I am using auth0 lock to sign up but now I need to add them to my Database so in order to do that I need the email and auth0 user id.
I am trying to find a way to detect when a new user signs up like The 'authenticated' event that is emitted after a successful sign-in lock.on('authenticated', function(authResult) { });
The question is how to get user info after auth0 sign up?
You can use getUserInfo API of Lock as described here
// Listening for the authenticated event
lock.on("authenticated", function(authResult) {
// Use the token in authResult to getUserInfo() and save it to
localStorage
lock.getUserInfo(authResult.accessToken, function(error, profile) {
if (error) {
// Handle error
return;
}
document.getElementById('nick').textContent = profile.nickname;
localStorage.setItem('accessToken', authResult.accessToken);
localStorage.setItem('profile', JSON.stringify(profile));
});
});

I'm currently integrating a frontend with a 3rd party backend that offers sign-in with social media. I'm using the Google JS SDK https://accounts.google.com/gsi/client which works fine with the one-tap login as it returns an ID Token which the backend requires. However, the downside is, if the user doesn't have a Google session, the prompt won't show.
If the user isn't logged in to Google, I've managed to prompt a login form and request a token on successful login, however, it only returns an access token. Is any way to request an ID token?
Example:
google.accounts.id.prompt(async notification => {
if (notification.getNotDisplayedReason() === 'opt_out_or_no_session') {
const tokenClient = google.accounts.oauth2.initTokenClient({
client_id: googleClientId,
scope: 'openid email profile',
})
tokenClient.callback = response => {
// response only has access token and no ID Token
}
tokenClient.requestAccessToken({ prompt: 'consent' })
}
window.addEventListener('load', () => {
google.accounts.id.initialize({
client_id: googleClientId,
callback: (user: CredentialResponse) => {
const { credential: idToken } = user
// I need idToken in the above requestAccessToken too
},
})
})
})
You are initializing two different namespaces in the example you have provided. The first one initializes oauth2 namespace, which starts the authorisation flow. This flow results in the acquisition of an access_token as you've realised.
The second one initializes the id namespace, which is responsible from the authentication flow. This returns an id_token, which is what you need indeed.
To keep using authentication flow beyond the capability of one-tap log in, you can render a Sign-In with Google button using the authentication initialisation. Simple initialise google.account.id.initialize() as you would. Then call one-tap prompt.
google.accounts.id.prompt();
Then in addition to that, you can render the button:
google.accounts.id.renderButton(document.getElementById("g-btn"), {
type: "standard",
logo_alignment: "left"
});
And
<div class="google-button" id="g-btn"></div>
Regardless of how the user decides to sign-in, it'll lead to the same callback method you've defined in the initialize() call.
I am making an app and I am using Cognito for auth. However, When I register, the account shows up in cognito but I receive a verification code and I have to manually confirm the account. I have a screen where I let the user add the code that they received to activate their account. Can anybody help me on what call do I send to Cognito in order to activate my account without having to manually confirm?
const signup = (event) => {
event.preventDefault();
if (formValidation()) {
UserPool.signUp(username, password, [], [], (err, data) => {
if (err) console.error(err);
console.log(data);
});
}
};
This is the function I am using to sign up users. How do I confirm the user?
You can use admin confirm sign up to confirm user without entering the verification code. As this is an admin method, the call will need to be authenticated with AWS credentials that have the right to perform this action.
Link to documentation:
https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/CognitoIdentityServiceProvider.html#adminConfirmSignUp-property
I am building a react native application and am using Firebase, more specifically firestore, in order to manage my data. My current objective is to implement an auto login feature on my app, where if the user exits the app, I want them to stay signed in, unless they manually hit the Sign Out button before exiting the app. Here is my current process of doing this:
When the user logs into the app, I sign them in by:
firebase.auth().signInWithEmailAndPassword(email, password).
I then get their idToken by:
let authIdToken = "";
firebase
.auth()
.currentUser.getIdToken(true)
.then(function (idToken) {
authIdToken = idToken
})
.catch(function (error) {
console.log(error)
});
I then want to save this token into the phone, so when the user opens the app again, I can fetch this token and check its validity. If it is valid, then I can log the user in using their idToken. In react native, I can do this by doing:
AsyncStorage.setItem(
"userData",
JSON.stringify({
token: token,
})
);
Now when the app loads up:
const startScreen = props => {
useEffect(() => {
const tryLogin = async () => {
const userData = await AsyncStorage.getItem("userData");
const transformedData = JSON.parse(userData);
const { token } = transformedData;
await firebase
.auth()
.verifyIdToken(token, true)
.then((payload) => {
console.log(true)
})
.catch((error) => {
if (error.code == "auth/id-token-revoked") {
// Token has been revoked. Inform the user to reauthenticate or signOut() the user.
console.log("revoked")
} else {
console.log("error")
}
});
};
tryLogin();
}, []);
The Issue: When I try to verify the token this way, I am met with the following error: firebase.auth().verifyIdToken is not a function.
I read through the documentation and am unsure of how else to verify this token using JS. How do I verify it? Let me know if my verification process is incorrect and how it should be done. I am new to using firestore and doing authentication in general and hope to learn how to do it the right way.
Another helpful note: This is how I am configuring my firestore: !firebase.apps.length ? firebase.initializeApp(firebaseConfig) : {};
Thanks!
I then want to save this token into the phone, so when the user opens the app again, I can fetch this token and check its validity.
This is completely unnecessary. Firebase Auth with persist the signed in user, and automatically refresh the token without you having to do anything. All you need to do is listen to when updates to the token are made available, and act on the new token as needed. You can establish an ID token listener using onIdTokenChanged as shown in the linked API documentation:
firebase.auth().onIdTokenChanged(function(user) {
if (user) {
// User is signed in or token was refreshed.
}
});
Once you have this token, you know that the user is successfully signed in. There is nothing left to do. There is no need to use it to sign in.
Also, you can't verify the token on the frontend. The verifyIdToken method you're looking at is for the Admin SDK only, which only runs on the backend. The idea is that you get the token on the fronend, then pass it to the backend as described in the documentation for the Admin SDK. The backend uses this to securely determine if the user on the frontend is who they say they are.
Since you didn't say if you have a backend or not, dealing with this token might not be necessary at all. If you just want to know when the user is signed in (even if they are just returning to the page after being away, then you can skip everything above and just use an auth state observer. Again, Firebase Auth persists information about the user so you don't have to sign them in again. The observer will tell you when the automatic sign-in is complete, or if they are not signed in at all.
I am using Firebase Cloud Functions with Express and Firebase Hosting to serve my multi-page site. I have successfully implemented server-side cookies as explained here and as implemented below:
function verifyLogin(request, response, next) {
const sessionCookie = request.cookies.__session || '';
firebase.auth().verifySessionCookie(sessionCookie, true /** checkRevoked */ )
.then((decodedClaims) => {
//serve content for user
return next();
}).catch(error => {
// Session cookie is unavailable or invalid. Force user to log in.
console.log(error);
response.redirect('/login');
return;
});
}
app.get('/', verifyLogin, (request, response) => {
var page_title = "Home";
response.render('index', {
page_title,
});
});
I am using the Firebase Web SDK (JavaScript) to access the Firebase Cloud Firestore. In order to do this, I need to get the idToken on the client side for the currently-logged-in user, like so:
firebase.auth().onAuthStateChanged(firebaseUser => {
if (firebaseUser) {
firebase.auth().currentUser.getIdTokenResult()
.then((idTokenResult) => {
// Access the Firebase Cloud Firestore here
});
}
});
This seems redundant to me, since I already know which user is signed in via my server cookie, but how else can I get the idToken without another call to Firebase Auth?
Is there a way to extrapolate it from my session cookie somehow and pass it to my client from my cloud function as a variable?
Or is there another way to look at this philosophically that I am overlooking?
In the same way you can listen to user sign-in state changes using onAuthStateChanged(), you can also listen to user ID token changes using onIdTokenChanged(). You will only need to use a new token when the observer you attach shows that a new one appears (for example, when it's refreshed every hour by the SDK).
Sorry this question is kind of long, it's because I've been trying to solve this problem for a while and want to make sure I don't leave any info out. I'm building a Cordova app and using Firebase for the authentication/database back end. I've been trying to authenticate users into Firebase using a Log in with Facebook button for almost a week now, but I haven't been able to get it to work.
Originally I tried following Firebase's example here: https://firebase.google.com/docs/auth/web/facebook-login (I need to use the "Advanced: Handle the sign in flow manually" as it is a Cordova Android & iOS app), this example didn't work for me as the link to Facebook's SDK script (//connect.facebook.net/en_US/sdk.js) kept throwing the error:
file://connect.facebook.net/en_US/sdk.js Failed to load resource: net::ERR_FILE_NOT_FOUND
I tried to fix this error in several ways, such as:
Changing it to https://connect.facebook.net/en_US/sdk.js (this resulted in the error: Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings. )
Added the links in question to the list of "Valid OAuth redirect URIs" and domains in the Facebook app settings
Storing the file in my local file system (and locally inside the app on my phone)
Including the entire SDK inside the head of my index.html file
None of these attempts worked. So instead I decided to use the plugin cordova-plugin-facebook from here: https://github.com/bisrael/cordova-plugin-facebook
This is the code I'm using to get the user's information from Facebook with the plugin:
function logInWithFacebook(){
CordovaFacebook.login({
onSuccess: function(result) {
console.log(result);
console.log(result.authToken);
// Store or send the user auth/access key here?
// Get user's name
retrieveUserDetails();
if(result.declined.length > 0) {
alert("The User declined something!");
}
},
onFailure: function(result) {
if(result.cancelled) {
alert("The user doesn't like my app");
} else if(result.error) {
alert("There was an error:" + result.errorLocalized);
}
}
});
}
function retrieveUserDetails(){
// Now that the user has authroised the app, make request to CordovaFacebook plugin to get user's name
CordovaFacebook.graphRequest({
path: '/me',
params: { fields: 'name' },
onSuccess: function (userData) {
console.log(userData);
console.log(userData.name);
// Here somehow send the retrieved username and send it to the Firebase function so that it's linked with the auth key.
},
onFailure: function (result) {
if (result.error) {
Error.log('error', 'There was an error in graph request:' + result.errorLocalized);
}
}
});
}
I'm now able to click on a log in button and log in successfully through Facebook. That process is returning a user auth/access key and the user's name from Facebook.
As I understand it, the manual log in flow example in Firebase's docs (https://firebase.google.com/docs/auth/web/facebook-login) takes the key returned from Facebook, converts it into a Firebase key, and then enters the user's newly created Firebase key and their username into Firebase's servers.
This seems pretty straight forward in the following sample code:
function checkLoginState(event) {
if (event.authResponse) {
// User is signed-in Facebook.
var unsubscribe = firebase.auth().onAuthStateChanged(function(firebaseUser) {
unsubscribe();
// Check if we are already signed-in Firebase with the correct user.
if (!isUserEqual(event.authResponse, firebaseUser)) {
// Build Firebase credential with the Facebook auth token.
var credential = firebase.auth.FacebookAuthProvider.credential(
event.authResponse.accessToken);
// Sign in with the credential from the Facebook user.
firebase.auth().signInWithCredential(credential).catch(function(error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
// The email of the user's account used.
var email = error.email;
// The firebase.auth.AuthCredential type that was used.
var credential = error.credential;
// ...
});
} else {
// User is already signed-in Firebase with the correct user.
}
});
} else {
// User is signed-out of Facebook.
firebase.auth().signOut();
}
}
function isUserEqual(facebookAuthResponse, firebaseUser) {
if (firebaseUser) {
var providerData = firebaseUser.providerData;
for (var i = 0; i < providerData.length; i++) {
if (providerData[i].providerId === firebase.auth.FacebookAuthProvider.PROVIDER_ID &&
providerData[i].uid === facebookAuthResponse.userID) {
// We don't need to re-auth the Firebase connection.
return true;
}
}
}
return false;
}
FB.Event.subscribe('auth.authResponseChange', checkLoginState);
My question is, how can I send the auth key and username returned from the Cordova plugin code, to Firebase's example code so that it works smoothly?
Firebase's example code includes this listener which listens for any change in the Facebook authorization status: FB.Event.subscribe('auth.authResponseChange', checkLoginState); but as this uses Facebook's SDK it won't work with my current set up.
I'm using the following Firebase chat app as a template to work from: https://gist.github.com/puf/8f67d3376d80ed2d02670d20bfc4ec7d as you can see it has a Login with Facebook button, but no code for handling the process, I'm trying to apply parts of the manual log in flow example in Firebase's docs (https://firebase.google.com/docs/auth/web/facebook-login) with data returned from the cordova-plugin-facebook queries, and integrate both with Firebase's chat app template.
I'm really at a loss as to what to do next, I've tried everything I can think of. Any help in solving this problem would be really, really appreciated.
Thank you in advance!
UPDATE
Questions and answers:
How does it work at the moment?
Right now I have a "Facebook Login" button - when this is clicked it runs logInWithFacebook(). This function uses the CordovaFacebook plugin, it also runs the function retrieveUserDetails() after the user signs in with Facebook. retrieveUserDetails() gets some user info from Facebook which I hope to then insert into my Firebase database.
logInWithFacebook() works correctly (it opens up a Facebook login page, and when the user logs in, I'm able to console.log the user's Facebook ID, and the Facebook access Token.
retrieveUserDetails() also works correctly (I'm able to console.log the user's name taken from Facebook).
How do you want it to work?
I'm happy with how the first half of the process is working (the logging in with Facebook and retrieving user details is working correctly). However I want this log in to trigger Firebase's auth state change listener, so that Firebase detects and confirms that the user has logged in:
firebase.auth().onAuthStateChanged(function(user) {
if (user) {
console.log("User is signed in.");
} else {
console.log("User is not signed in.");
}
});
What is not working the way you want?
The first half of the process is working correctly, but I'm lost when it comes to what to do with the accessToken returned from Facebook. From reading the docs I think that Firebase is supposed to convert this token into a Firebase access token, and then that is used to log the user into Firebase (this would also trigger the above AuthStateChanged function). From there I want to be able to insert any data I've retrieved from Facebook (the user's name etc) into my Firebase database. But the main problem is getting the Facebook accessToken converted into a Firebase login (the second block of code in my original question is where I'm trying to perform the conversion/sign into Firebase).
Because I'm using Cordova, this method (logging into Facebook with a plugin and then handling the conversion of the accessToken) seems to be the only way to log in with Facebook. But I'm totally lost on how to complete the second half.
UPDATE 2
I've trimmed parts from the sample convert-Facebook-token-to-Firebase-token code from the docs so that the Facebook SDK isn't required. And it appears to be working. This is the code after cutting away the SDK related parts:
// First, define the Facebook accessToken:
var FBaccessToken = result.accessToken;
// Build Firebase credential with the Facebook auth token.
var credential = firebase.auth.FacebookAuthProvider.credential(
FBaccessToken);
// Sign in with the credential from the Facebook user.
firebase.auth().signInWithCredential(credential).then(function(user){
console.log("It looks like we signed into Firebase with the Facebook token correctly.");
}, function(error) {
console.log("Something went wrong, user isn't signed into Firebase with the FB token.");
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
// The email of the user's account used.
var email = error.email;
// The firebase.auth.AuthCredential type that was used.
var credential = error.credential;
// ...
});
I still need to add the user's email from Facebook and try to send that while logging into Firebase too - so that I'll have some identifier for the user in the Firebase console, but this is a good start.
2nd UPDATE
The below code successfully gets user data from Facebook after the user authorizes the app:
CordovaFacebook.graphRequest({
path: '/me',
params: { fields: 'first_name,last_name,email,locale,gender,age_range,picture.width(200).height(200)' },
onSuccess: function (userData) {
console.log(userData)
var first_name = userData.first_name;
var last_name = userData.last_name;
var email = userData.email;
var locale = userData.locale;
var gender = userData.gender;
var min_age = userData.age_range.min;
var profile_picture = userData.picture.data.url;
// Enter user details into the Firebase database:
firebase.database().ref('users/' + uid).set({
first_name: first_name,
last_name: last_name,
email: email,
locale: locale,
gender: gender,
min_age: min_age,
profile_picture : profile_picture
});
console.log("Facebook user data should now be in the database!");
},
onFailure: function (result) {
if (result.error) {
Error.log('error', 'There was an error in graph request:' + result.errorLocalized);
}
}
});
(Just an answer to the last update, as you figured out the rest :))
How to get user email from CordovaFacebook.login()
Looking at the CordovaFacebook documentation you can add a permissions property on the object passed to the login method.
According to the Facebook API documentation the permission name for email is just "email".
I haven't tested, but I think this should work:
CordovaFacebook.login({
permissions: [ 'email' ],
onSuccess: function(result) {
console.log('email:', result.email);
...
},
onFailure: function(result) {
...
}
});
