In the Symfony Lexik JWT Authentication bundle, It is explained how to authenticate users using a table in the database.
In my case, My users aren't in the database but are in another application that I can access via API calls.
Also, to retrieve the users from this API, all I have to do is send a token associated with every user and get his information.
This token is well handled and is unique for each user.
How can I change the way LexikJWTAuthenticationBundle authenticate users using this API instead of the database.
And after this authentication, I want the JWT token to contain all the user information so I won't have to call this API each time a request is made to my application.
I made this diagram to explain my situation:
I tried from my side building a custom ApiUserProvider and an ApiUserAuthenticator but I am struggling to get this working.
Any help?
Here's described how to manually create JWTs for users: https://github.com/lexik/LexikJWTAuthenticationBundle/blob/2.x/Resources/doc/7-manual-token-creation.md you should be able to use that in your endpoint which authenticates the user, and return your own JWT.

I'm working on the custom express API based on the single Cloud Function and I'd like to secure the endpoints with the authentication. I'm aiming for implementing the API key flow and OAuth 2.0 authorization code flow. In my endpoint functions I'd need to obtain the user id somehow and I was wandering how can I archive that. Should I mix Firebase Token (createCustomToken) with these auth flows? e.g in the API key flow when user generates a new token on the frontend then on the backend I should create a Firebase Token instead of custom hashed token and store it in db?
Any ideas how to do it properly, maybe are there any other/better ways to retrieve the uid?
I need to use the authentication service from firebase. but use my existing authorization service.
Can i use user token, sessions info from firebase.auth().onAuthStateChanged(function(user) {})
what is the best way/ways to manage these kind of use cases.
Should i also store my user details cookies, token etc?
You can implement a custom provider for Firebase Authentication. In this process:
You sign the user in to your service with their credentials as usual.
You then mint a token based on the user's profile.
The user then uses that token to sign in to Firebase.
The entire process is quite well documented on the links I included above.
My Symfony (4.4) app uses the OneloginSamlBundle bundle to authenticate users against a SAML identity provider. This works fine. I receive the SAML response and the User Provider instantiates my User class correctly. However, I want that once I get the authentication SAML response, the corresponding user is instead fetched from my database. How could I do this ?
I guess I need to create a custom user provider which would use the OneloginSamlBundle userprovider AND then fetch the user, but I don't know how I am supposed to do it with Symfony.
Is it possible to use a custom authentication provider which I don't have any control over?
I develop an app in addition to a teachable course. Teachable is a platform like shopify where you can create online courses.
I want to use it as an auth provider, so a user, that already has an account can login with his teachable account.
To my knowledge custom authentications with auth tokes work like this: I send a request to my server with the entered user credentials. From my server I use these credential to login to teachable, if that was successful my server gets a callback and I return a token to my client, so the login was successful.
However as far as I know teachable doesn't have an api option for me to login and get a callback if it was successful.
What can I do about this? Also are there any security issues I didn't realized?
Your understanding of the flow to add a custom provider to Firebase Authentication is correct. You need to be able get the authenticated token from the provider, and mint a Firebase custom token from it.
If the provider you're looking to add doesn't have an API, you won't be able to add it as a custom provider to Firebase though.
I don't immediately see another way to connect the provider without an API.
Mainly token are used for authentication but firebase provides different
Sign-in providers like email and password, Facebook, Google, GitHub and Anonymous for authentication. Then what are this tokens used for?
Can anybody guide me to a use case where this custom tokens are useful?
Here's where I got to know about this Custom tokens:
https://www.youtube.com/watch?v=VuqEOjBMQWE&t=93s
https://firebase.google.com/docs/auth/admin/create-custom-tokens
Custom tokens are used when you want to use a Custom Auth System:
You can integrate Firebase Authentication with a custom authentication
system by modifying your authentication server to produce custom
signed tokens when a user successfully signs in. Your app receives
this token and uses it to authenticate with Firebase.
For example: Let's say you're developing an app that needs authentication, but you don't want to use the Auth Providers that Firebase supports (Google,Twitter,Facebook,etc). Let's say you want to use Instagram Auth.
Since Instagram Auth is not provided by Firebase you can't set your Realtime Database rules to auth!=null. You'll probably set it to public, which means that anyone can access your data and this is an obvious security risk(Your database is not safe at all).
So what you can do is create your custom auth system that allows a user to authenticate with Instagram and then give him a Custom Token. The user will then use this token when signing in to your Firebase App, and he will be recognized on Firebase Authentication. Which means that he can now access data that is protected by auth!=null. Your database no longer needs to be public.
