In this article, we will implement authentication routing guards and also implement interceptors to invoke the refresh token API. Click here for part-1 angular jwt token authentication & refresh token . Route Guards: In our current sample, we have an issue with the navigation that is like after login user can access the login page which is not correct, and without login can access the 'fav-movies' page. So we can correct this issue by integrating the routing guards. Let's create a routing guard service like 'AuthGuard'. ng generate class shared/auth/auth-guard --skip-tests src/app/shared/auth/auth-guard.ts: import { Injectable } from '@angular/core'; import { ActivatedRouteSnapshot, CanActivate, Router, RouterStateSnapshot, UrlTree, } from '@angular/router'; import { Observable } from 'rxjs'; import { AuthService } from './auth.service'; @Injectable() export class AuthGuard implements CanActivate { constructor(priv

In this article, we are going to implement JWT(JSON Web Token) authentication in the Angular(v14) application. We also understand how to use the Refresh Token when the JWT Access Token expires. JSON Web Token(JWT): JSON Web Token is a digitally signed and secured token for user validation. The JWT is constructed with 3 informative parts: Header Payload Signature Create An Angular(v14) Application: Let's create an Angular(v14) application to accomplish our demo. Command To Create Angular App ng new name_of_your_project Let's install the bootstrap package npm install bootstrap@5.2.0 Configure the bootstrap CSS and JS file reference in 'angular.json'. Now let's add the bootstrap menu in 'app.component.html'. src/app/app.component.html: <nav class="navbar navbar-dark bg-primary"> <div class="container-fluid"> <a class="navbar-brand" routerLink="/">Jwt Auth Demo</a> </div> </nav

In this article, we will implement Vue3 application authentication with the JWT auth cookie. So in this portion, we mainly target access token utilization. To know about Jwt authentication in vuejs like managing token using browser storage then check below mentioned articles. Part-1 Jwt Access Token Auth In Vue3 Part2 Refresh Token In Vue3 HTTP Only JWT Cookie: The HTTP only cookie is only accessible by the server application. Client apps like javascript-based apps can't access the HTTP-only cookie. So if we use authentication with HTTP only JWT cookie then we no need to implement custom logic like adding authorization header or storing token data, etc at our client application. Because once the user authenticated, that auth cookie will be automatically sent to the server by the browser on every API call. Authentication API: To implement JWT cookie authentication we need to set up an API. For that, I had created a mock authentication API(Using the NestJS Server framework). So d

Part3  we had enabled the JWT token validation and discussed different authorization techniques as well. In this article, we will understand Refresh Token creation and its usage. When To Use Refresh Token: A refresh token is a unique random encrypted string. On the expiration of the JWT auth access token, instead of showing a login page to the user, we can make the user authenticated immediately using the refresh token. By using refresh token we can fetch new user access tokens from the server without any user credentials. Generate Refresh Token: In 'AuthLogic.cs' file add a new private method like 'GenerateRefreshToken()'. Logics/AuthLogics.cs: private string GenerateRefreshToken() { var randomNumber = new byte[32]; using (var generator = RandomNumberGenerator.Create()) { generator.GetBytes(randomNumber); return Convert.ToBase64String(randomNumber); } } Here using 'System.Security.Cryptography.RandomNumberGenerator' generated refresh token of leng
