I have tried the sample app of Quarkus and JWT Security Sample App
How can I implement JWT refresh token in Quarkus Framework?
You have to options here, which are basically the same, you have to invoke keycloak through the rest api in order to get your refresh token. You can do that by using a rest-client, like in here or an adapter, this are your options with the jwt integration.
If you instead use a different dependency like the oidc client you will be able to create new tokens and have more options, check this guide.
Thanks

Im trying to make an .NET 5 Web Api works with Jwt Bearer token. I want some operations to be secured by using a token that comes from another issuer. The token would be generated by MS Azure AD. The application will read the token from the request header, validate it and extract the user's roles for more validations. The app shoudn't be the issuer of the token.
Is this possible? I tried so many ways to make this works without success. I setup Swagger to use OpenId Connect with Microsoft Azure and then the bearer is used to call the secured operations but always got errors. Now I don't understand how Dotnet Core Authencation and Authorization works.
Thanks in advance!
That will definitely work OK but requires an understanding of the science:
AZURE AD TOKENS
I would first look at the JWT in an online viewer. There is a known issue with the default setup where you get JWT access tokens that cannot be validated. See Step 3 of my blog post for details.
UNDERSTAND PRINCIPLES
Validating a JWT involves the general steps in this blog post. Once you understand this it will hopefully unblock you.
C# JWT ACCESS TOKEN VALIDATION IN APIs
The Microsoft framework often hides the required logic, which doesn't always help, and the option I prefer is to validate JWTs via a library.
Aim to understand how to use the JwtSecurityTokenHandler class to validate a JWT manually, eg in a console app. Maybe borrow some ideas from this C# code of mine.
C# AUTHORIZATION
Once JWT validation works, the next step is to use the details in the ClaimsPrincipal to determine whether to allow access to data. I would get on top of the JWT validation first though.
I have 2 different applications.
Let's say A & B.
A is being used for login/signup and users related activities.
And It is also used for Generating JWT Token and validation as well.
Now, the other application B is used for some very specific operations.
I want to use the same JWT token I generate from application A to validate users and extract useful information from the token.
Can someone please suggest to me what design should I follow?
Should I use 2 different JWT validators?
Actually is nothing wrong to use service A as an Authorization Service that issues JWT tokens and the B service as a resource service
here is a posts described how to do it in ASP.NET Web API
Token based authentication
I am developing a Flutter mobile application with a Spring Boot backend. I want to have three types of login methods (1). username & password (2). Facebook (3). Google.
I have following questions.
1) If I handle the Authentication part in the mobile App via Firebase Authentication (And store all the user on Firebase), do I need to write authentication code on my Spring Boot side? Or I need to keep my authentication on the Sprin Bboot side only?
2) I want the JWT token for all the authentication system (Facebook, Google and username & password). The mobile app will send the JWT token for every requests it make to the Springboot app.
3) I am looking for a step by step tutorial that shows how can I integrate all these login methods in my Springboot REST APIs. I have looked many but all they have some different different methods or dependencies. Like some are adding Facebook dependency in the maven and some only add the Oauth2.
Thanking you in advance
You can integrate your Spring Boot back-end with external authentication provider using JWT by defining a custom security filter in your spring boot app. This filter will read the JWT issuer (iss) and define where it comes from (Facebook or Google). Then, based on the provider, use the appropriate public key to verify the signature included in the JWT (normally, you can use the JWKS URI provided by the authentication providers to get the key). If all good, authentication is success.
I use
Flutter
Spring for database access (REST)
Firebase for authentication
The problem was: how do I authenticate REST requests?
The short answer: send the Firebase access token to the Spring server where the token is validated. If it is valid, grant acces. Else return 403 forbidden.
The more detailed answer:
Authenticate in Flutter
FirebaseAuth.instance.signInWithPopup(GoogleAuthProvider())
Get the JWT access token IFF login was successful. (You may rather use userCredential.user instead of currentUser)
FirebaseAuth.instance.currentUser!.getIdToken();
Add the token to your http-request header
final response = await http.get(
Uri.parse('https://example.com/example'),
headers: {
HttpHeaders.authorizationHeader: 'your_api_token_here',
},
);
Then validate the token on server side. Read this for details:
https://firebase.google.com/docs/auth/admin/verify-id-tokens#java
FirebaseToken decodedToken = FirebaseAuth.getInstance().verifyIdToken(idToken);
String uid = decodedToken.getUid();
Your Spring application will be able validate that the token is correct and not yet expired.
I highly suggest to send the token over https only! Do not use http.
Question
I got a problem with understanding some basic thing about auth0, probably someone can help me out.
In the tutorial SPA + API one of the first lines in the TDLR is this:
Both the SPA and the API must be configured in the Auth0 Dashboard
I dont understand why I need to configure the API on Auth0. My code seems to work so can anyone help me understand if I do something wrong or what the advantages are if I actually add a custom API in my dashboard?
Setup
SPA (React)
Auth0
REST API (ktor)
What I do
Created a SPA on Auth0
Login on my SPA through Auth0 to get a JWT (google token)
Sending the JWT as authentication bearer in my calls to the REST API
REST API verifies the JWT token with a JWK provider using the Auth0 url mydomain.eu.auth0.com/.well-known/jwks.json.
Authentication seems to work
Great question, I am assuming that your authentication request includes audience parameter which represents your custom API(Rest API)right now. In oauth2 terms, it is called Resource Server. Each resource server can have many permissions which you include in the scope when initiating the authentication request. Let's step back and talk about the token format. Auth0 issues token in two formats:
Opaque strings: When not using a custom API
JSON Web Tokens (JWTs): When using a custom API
https://auth0.com/docs/tokens/reference/access-token/access-token-formats#how-does-all-this-affect-the-token-format-
As explained above link, the token format depends on the audience (Custom API) parameter. Therefore, when the authentication request includes audience, auth0 issues JWT token with all necessary permission. Then, you need to validate the JWT token in your API server before returning the resources to your front end client.
It should make sense why you need to create custom API in auth0 and define permissions. If you do not create custom API in auth0, there is no way to know what kind of permission you need in the token which will generate an error(invalid audience specified)
I am new to Fuel PHP... I am working on a project with REST architecture in Fuelphp..... I didn't found any tutorial how to achieve the required functionality "User Authentication using Fuel PHP REST".
As REST server is stateless how do we use auth package of fuelphp in rest api?
As you also pointed, REST calls are somewhat stateless meaning you have no session to store.
The auth documentation has some methods which checks user credentials, but does not store authentication. There are no offical way of doing this.
One of the methods that I have used in the past is to use a token based system. You have an API token linked to an Auth user then this token is supplied in the Authorize header when making a request, the token is then checked against known tokens and if valid a forced login is performed with the Auth package.
