In Firebase, it is possible to log in a user as anonymous with a token, and when the user decides to register, just update the credentials. I have a hard time understanding whether the same is possible with Auth0.
We are now using Auth0 as identity provider, the flow is the following:
The user is using the app anonymously with limited access.
User registers in the app with Auth0.
Auth0 issues a token
Firebase receives the token and lets the user use the restricted parts. All the data generated by the anonymous user is lost
What I want to achieve:
When the user starts using the app, Auth0 immediately creates a user token
The token is valid to access certain parts of Firebase database
If/when the user decides to register, their token remains valid but receives additional credentials
Firebase lets the user use the restricted parts
It's Konrad from Auth0 Community Team. Yep as Baskaro said unfortunately it's not supported from our side of stack. It will be great if you can submit it as a feature request to our product team using our feedback form (you will be contacted by one of our product managers within 10 business days):

background of this question
I'm using firebase auth for user authentication on my app.
I realized that firebase doesn't have a log of user information changes, so I can't answer user questions about it.
So, I'm planning to move the feature of changing user account info (like email, display name, and password) from using the client-side firebase auth library to using server-side firebase auth SDK for the purpose of taking logs of these changes to use for user support. Also, I'd like to make logout a user who changes account info.
I've looked for the appropriate API on the document firebase.google.com/go/v4/auth and found UpdateUser function. The struct UserToUpdate which is a parameter of UpdateUser can set a new email address, new password and new display name, but I can't find to set the parameter to make a user logout.
my question
Is there a way to log out a specific user by firebase auth go SDK?
Firebase Authentication's client-side sign-in is based on ID tokens, which are valid until their built-in expiration (by default: an hour after they are minted). Since no server keeps a list of all the ID tokens it has minted, there is no way to mark a token as invalid on such a list either.
The common approach to revoke access for a user is to:
Revoke the refresh token, so that they can no longer mint new ID tokens with it.
Add the ID token(s) of the user to a self-managed list of revoked ID tokens.
Detect the presence of an ID token in this list from your server-side code and security rules.
Optionally detect the refresh token revocation on the client
Instead of logging the user out, you can also force-refresh their ID token/profile on the client to get the latest information from the server.
My system works as follows;
I have an ASP.Net RESTful API server, which contains a user database.
I also have a Xamarin.Forms application, with a registration and login page.
What I want is to have the ability to authenticate a login using a social IdP, and then, if that user has not been logged in before, register that user in my local database.
I have been reading up on how to implement OAuth 2.0 with OpenID Connect to authenticate my users with a social IdP, however, I cannot seem to wrap my head arround it. From what I've read, I shouldn't use an Access token for authentication, since that i what the ID token is for, however, I have also read that the only intended purpose for an ID token, is the client.
My problem then is, how can I make sure that calls made to my ASP.Net server, has been made by "real person", and how do I determine who makes the call?
Access token will be used determine whether the client application was authorized by a user to access a resource. The concept of ID token comes from OpenID Connect. Main purpose of the ID token is to authenticate the user to the client application (i.e. letting the client application know that the person who authorized the access is a valid person).
To do this, you have to validate the ID token. This can be done using third party libraries such as nimbusds or auth0. You can validate the signature of the token verify the integrity of the token and check the claims included in the token (by comparing them with expected values) to verify the user details. Also, you can add custom claims (any claim that is specific for your application/implementation) to the tokens through your identity provider so that you'll be able to validate those particular claims in order to verify the user.
I wonder if anyone can help. I'm trying to plan the AWS services that I'll need, and how they hang together, for a web application I'm planning.
Specifically I'm thinking about the user registration and login process using Cognito and DynamoDB.
Users will need to be registered and logged in in order to perform some actions. I'm thinking serverless, so these actions will be Lambda functions fronted by API Gateway. As with many websites, I'd like to use Facebook as the user authentication model. I'm thinking I need:
To create a Facebook application
To configure Cognito Federated Identities with the Facebook app id
To have a DynamoDB table to contain user information
To provide a facility to allow a user to register using their Facebook identity
On registration, create a record in the DynamoDB user info table with user's name, email etc as taken from their Facebook profile
To provide a facility for registered users to login with their Facebook identity
To somehow pass the user token (JWT token ?) on subsequent client requests to API Gateway endpoints
So far I've created the Facebook app and have an application ID. I've created the Cognito Federated Identity for the app and configured it with my Facebook app id. And I have set the Authorisation field for the Method Request for the API Gateway to "AWS_IAM"
Using the Facebook javascript SDK and the AWS javascript SDK, I've put together a very basic page that allows login via Facebook, then creates a new AWS.CognitoIdentityCredentials object with the facebook authResponse accessToken. Lastly it calls AWS.config.credentials.get to get the Cognito credentials. But this isn't really the steps above - it just proves that a user can login with their Facebook id and I can pass it to Cognito.
My specific questions therefore are:
What I'm trying to work out is how to do registration. Once the user has logged in via Facebook, how can I create a user record in DynamoDB?
And likewise, when a user goes to login (rather than register), once the user has logged in via Facebook, how can I ensure they have a user record in DynamoDB? (because if they dont have a record, then presumably they've not registered)
Lastly, how can I pass the user id / token from the client to an API Gateway endpoint?
I'm not looking for code samples etc - just pointers as to whether I'm thinking along the right lines or barking up the wrong tree. A high level of how the various components need to hang together would be great, as would any links or references to similar ideas of concepts.
Thanks
I am working on Firebase application ( Firebase version 4.1.3 )
My health care related application is made for dependent group of people such as children and seniors. However, most of my users are independent group of people age around 18-55. Most of my users use my application for their seniors/children. They need to create account for each of their family seniors/children member. Therefore, my users have to log in and out many times and they have to keep track of their family members' account. My first thought was I should make an account switching feature so that my user can switch their account back and forth between their family members to update information on my application.
After searches on Google, I found way to force switching account on Firebase authentication with Google provider, but those are not what I'm looking for.
My questions are:
Is it possible to store the multiple firebase auth objects (logged in object) in client side?
If it is possible, for how long will the token inside the firebase auth object last for?
If it doesn't last forever, is it possible to refresh update the token so that it can be use without authenticating with the social/phone login again?
The functionality you are asking for is not available out of the box. You have to build it on your own. I do think Firebase provides the pieces to allow you to build it (via Auth and Database).
Is it possible to store the multiple firebase auth objects (logged in object) in client side: You can have multiple Firebase app instances and each one have an auth instance with a current user. You would need to ask each user to authenticate though (you can't authenticate once and sign-in into all of the account). However, you can build your own user group login mechanism, where logging in with one "master" account can allow you to login with multiple accounts using custom Auth.
If it is possible, for how long will the token inside the firebase auth object last for. Firebase sessions are supposed to be indefinite. If a token expires (typically after one hour), it can be refreshed automatically if you are using real time database.
I do not think Firebase has that token capability. But what you could do is simply put the email address of the people in the device by Shared Preferences( for Android). When the user wants to log in with that user bring the email address just ask him to enter the password and then go through the log in process. If you do not want to use SharedPreferences you could simply store the users(also as you said family members) in Firebase Database and link them with the controller user so to speak. Whenever user wants the switch, go and bring the email addres of other family members from Firebase Database and ask in the client for the password and do the login by Firebase Authentication.Hope that helps!
I am currently using firebase to make an ionic app. I am using firebase simple login for social auth (facebook, twitter, email & password). The auth works perfectly, it $broadcasts the authed user. However it doesn't seem to create a user in the actual firebase db. I was wondering how I can get the users that have been authed using my app.
For most of the authentication protocols it supports, Firebase doesn't store user data anywhere. Even for the protocols where it does store data (I only know of email+password doing this), it stores this information in a place that your application can't access (though you can find those users in the dashboard of your Firebase).
To quote the Firebase documentation:
It does not store profile or user state in your Firebase. To persist user data you must save it to your Firebase.
What most applications end up doing, is keeping a list of users inside their Firebase that they manage themselves. So when a user first authenticates with the application, it creates a node under /users/<uid> that contains the information for that user.
See this section of the Firebase documentation that describes storing user data.
Firebase does not store profile or user state in your Firebase instance. To persist user data you must save it to your Firebase.
Firebase provides multiple authentications services
Using existing social login providers such Facebook, Twitter, Google, and GitHub. Using these services provides an option for your users to access your application without creating a new account.
Using built-in support for logging in with email & password. This requires registration and account creation that is handled by Firebase. The user account information is stored outside you application.
Using a custom authentication to implement existing server-side authentication, single sign-on, legacy systems, or third-party OAuth based services (such as Yahoo).
Once authenticated, Firebase return a variable auth to your application that you can use for authorization and access control. This variable is null for unauthenticated users, but for authenticated users it is an object containing the user's unique (auth.uid) and potentially other data about the user.
If you want to persist additional user information such as name
and location, then you need to use auth.uid and store it in your
Firebase with additional profile data.
Internally, Firebase generates JSON Web Tokens (JWTs) and creates authenticated sessions by calling Firebase.loginWithCustomToken() with those tokens. Each user is assigned a uid (a unique ID), which is guaranteed to be distinct across all providers, and to never change for a specific authenticated user.
The user data for firebase authentication is stored in firebaseLocalStorageDb in IndexedDB. After login to website, if you delete firebaseLocalStorageDb, the login user data for firebase authentication is all deleted so you need to log in website again.
