I am creating an app (Xcode, swift) that has a profile page for each user and I want their name to appear on that page.
I have been able to get their email address through:
let email : String = (Auth.auth().currentUser?.email)!
How would I gather the users name? I have the users UID as well.
I am using firebase by the way
If you are not using Google or Facebook to log in with firebase, You need to manually create the profile for each user. See Update a user's profile
If you're using a social provider to sign in, you can get the display name from that provider through Firebase with:
Auth.auth().currentUser?.displayName
If you're signing in with another provider, the display name won't automatically be set, and you will (as Abdullah answered) have to create your own registration system where the user enters their name - and you then store it in the displayName property of Firebase Authentication.
To achieve what you requested, you either have to use a social auth provider (such as Google or Facebook) or change it yourself from the client, as the other answers suggest.
First of all, you would have to create a changeRequest, using the following code
let changeRequest = Auth.auth().currentUser?.createProfileChangeRequest()
Once the change request is created, you can change whatever basic information you need to (either the photo URL or the display name) with the following code:
changeRequest?.displayName = "Lorem ipsum"
changeRequest?.photoURL = "https://your_link/path_to_image.png"
Finally, you must send the change request to Firebase, which will handle it and possibly return an error for you to handle.
changeRequest?.commitChanges { error in
if let error = error {
print(error.localizedDescription)
// You can handle the given error here
return
}
}
As others have already pointed out, you can find this and more information on the official on the official Firebase docs website.
I am using NSSharingService to prepare an email with attachment for the user of my macOS app. My code is:
let emailService = NSSharingService.init(named: NSSharingService.Name.composeEmail)
if emailService.canPerform(withItems: [emailBody, zipFileURL]) {
// email can be sent
DispatchQueue.main.async {
emailService.perform(withItems: [emailBody, zipFileURL])
}
} else {
// email cannot be sent
// Show alert with email address and instructions
self.showErrorAlert(with: 2803)
}
This works correctly, but if the code is executed on a fresh system, Apple Mail will be opened asking the user to configure an email account. Some users may not understand what is going on in this situation. Is there a way to ascertain if the default Email Client is configured, so that I can inform the user if it is not ? Thanks for your help.
Question says it all. In Firebase, how do I confirm email when a user creates an account, or, for that matter, do password reset via email.
I could ask more broadly: is there any way to send emails out from Firebase? E.g. notifications, etc. This isn't the kind of thing you would usually do client-side.
Update
Note that this was never a very secure way of handling email verification, and since Firebase now supports email verification, it should probably be used instead.
Original answer
I solved the email verification using the password reset feature.
On account creation I give the user a temporary (randomly generated) password. I then trigger a password reset which will send an email to the user with a link. The link will allow the user to set a new password.
To generate a random password you can use code similar to this:
function () {
var possibleChars = ['abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!?_-'];
var password = '';
for(var i = 0; i < 16; i += 1) {
password += possibleChars[Math.floor(Math.random() * possibleChars.length)];
}
return password;
}
Note that this is happening on the client, so a malicious user could tamper with your logic.
This would need to be done outside of firebase. I store users at /users/ and keep a status on them (PENDING, ACTIVE, DELETED). I have a small service that monitors users of a PENDING status and sends out a confirmation email. Which has a link to a webservice I've created to update the user status to ACTIVE.
[Engineer at Firebase - Update 2014-01-27]
Firebase Simple Login now supports password resets for email / password authentication.
Each of the Simple Login client libraries has been given a new method for generating password reset emails for the specified email address - sendPasswordResetEmail() on the Web and Android, and sendPasswordResetForEmail() on iOS.
This e-mail will contain a temporary token that the user may use to log into their account and update their credentials. This token will expire after 24 hours or when the user changes their password, whichever occurs first.
Also note that Firebase Simple Login enables full configuration of the email template as well as the sending address (including whitelabel email from your domain for paid accounts).
To get access to this feature, you'll need to update your client library to a version of v1.2.0 or greater. To grab the latest version, check out https://www.firebase.com/docs/downloads.html.
Also, check out https://www.firebase.com/docs/security/simple-login-email-password.html for the latest Firebase Simple Login - Web Client docs.
As at 2016 July, you might not have to use the reset link etc. Just use the sendEmailVerification() and applyActionCode functions:
In short, below is basically how you'll approach this, in AngularJS:
// thecontroller.js
$scope.sendVerifyEmail = function() {
console.log('Email sent, whaaaaam!');
currentAuth.sendEmailVerification();
}
// where currentAuth came from something like this:
// routerconfig
....
templateUrl: 'bla.html',
resolve: {
currentAuth:['Auth', function(Auth) {
return Auth.$requireSignIn() // this throws an AUTH_REQUIRED broadcast
}]
}
...
// intercept the broadcast like so if you want:
....
$rootScope.$on("$stateChangeError", function(event, toState, toParams, fromState, fromParams, error) {
if (error === "AUTH_REQUIRED") {
$state.go('login', { toWhere: toState });
}
});
....
// So user receives the email. How do you process the `oobCode` that returns?
// You may do something like this:
// catch the url with its mode and oobCode
.state('emailVerify', {
url: '/verify-email?mode&oobCode',
templateUrl: 'auth/verify-email.html',
controller: 'emailVerifyController',
resolve: {
currentAuth:['Auth', function(Auth) {
return Auth.$requireSignIn()
}]
}
})
// Then digest like so where each term is what they sound like:
.controller('emailVerifyController', ['$scope', '$stateParams', 'currentAuth', 'DatabaseRef',
function($scope, $stateParams, currentAuth, DatabaseRef) {
console.log(currentAuth);
$scope.doVerify = function() {
firebase.auth()
.applyActionCode($stateParams.oobCode)
.then(function(data) {
// change emailVerified for logged in User
console.log('Verification happened');
})
.catch(function(error) {
$scope.error = error.message;
console.log(error.message, error.reason)
})
};
}
])
And ooh, with the above approach, I do not think there's any need keeping the verification of your user's email in your user data area. The applyActionCode changes the emailVerified to true from false.
Email verification is important when users sign in with the local account. However, for many social authentications, the incoming emailVerified will be true already.
Explained more in the article Email Verification with Firebase 3.0 SDK
What I did to work around this was use Zapier which has a built in API for firebase. It checks a location for added child elements. Then it takes the mail address and a verification url from the data of new nodes and sends them forwards. The url points back to my angular app, which sets the user email as verified.
As I host my app files in firebase, I don't need have to take care of any servers or processes doing polling in the background.
There is a delay, but as I don't block users before verifying mails it's ok. Zapier has a free tier and since I don't have much traffic it's a decent workaround for time being.
The new Firebase SDK v3 appears to support email address verification, see here (put your own project id in the link) but it doesn't appear to be documented yet.
I have asked the question on SO here
See #SamQuayle's answer there with this link to the official docs.
As noted by various others Firebase does now support account related emails but even better, as of 10 days ago or so it also supports sending any kind of email via Firebase Functions. Lots of details in the docs and example code here.
I used following code to check the email verification after creating new account.
let firAuth = FIRAuth.auth()
firAuth?.addAuthStateDidChangeListener { auth, user in
if let loggedUser = user {
if loggedUser.emailVerified == false {
loggedUser.sendEmailVerificationWithCompletion({ (error) in
print("error:\(error)")
})
}
else {
print(loggedUser.email)
}
} else {
// No user is signed in.
print("No user is signed in.")
}
}
I used MandrillApp. You can create an API key that only allows sending of a template. This way even thought your key is exposed it can't really be abused unless someone wants to fire off tonnes of welcome emails for you.
That was a hack to get myself off the ground. I'm now enabling CORS from a EC2 that uses the token to verify that the user exists before extending them a welcome via SES.
How can I fetch the recently logged in iCloud user's AppleID, firstName, lastName via CKRecordID from CloudKit?
Firstly you need to fetch the User Record ID and then you check that there isn't an error, if so, then you can fetch the UserInfo for the ID that you just fetched and use the result the access the information that you want
container.fetchUserRecordIDWithCompletionHandler({
userID, error in
if (!error) {
container.discoverUserInfoWithUserRecordID(userID, {
userInfo, error in
})
}
})
You can then use the userInfo to find out the firstName and lastName simply by using dot notation.
eg. userInfo.firstName
I assume by the fact that you are using CloudKit that you are a registered apple developer and so i recommend you watch both of the WWDC videos on the topic. With the exception of subscriptions which don't work at the time of writing this, everything in the video is incredibly useful and in fact covers the question you asked. After watching them, you may also want to pick apart apples own app which they made with CloudKit, paying careful attention to AAPLCloudManager. The link below is for this app. Hope this helps!
https://developer.apple.com/library/prerelease/ios/samplecode/CloudAtlas/Introduction/Intro.html#//apple_ref/doc/uid/TP40014599
For firstName, lastName you can use this way, e-mail / appleID I still do not know:
var defaultContainer = CKContainer.defaultContainer()
var publicDatabase = defaultContainer.publicCloudDatabase
defaultContainer.discoverUserInfoWithUserRecordID(recordID, {userInfo, error in
println("firstName: \(userInfo.firstName?) lastName: \(userInfo.lastName?)")
})
Can we get email address using: users.getStandardinfo?
Please help me on this.
Thank you
You can't. But you can ask the user to provide it when he/she logs in.
There is proxied_email that can be taken from user table, you can try:
$personArray = $facebook->api_client->users_getInfo( $fb_config->user_id, "last_name, first_name, birthday, hometown_location, current_location, is_app_user, proxied_email" );
$email = $personArray[0]['proxied_email'];
if(empty($email)){
echo 'Proxied email was not retreived. Trying fql query...';
$facebookFQLResultXml = $facebook->api_client->fql_query("SELECT proxied_email FROM user WHERE uid=".$fb_config->user_id);
$email = $facebookFQLResultXml['proxied_email'];
}
But I am not sure for the result
So you can get the proxied email and contact the user through it but you
can't extract the original email:
proxied_email - A proxied wrapper alternative for contacting the user through email,
instead of directly calling notifications.sendEmail. If the user shared his or her proxied
email address with you, this address also appears in the email field (see below).
