JWT Authentication Best Practices

The importance of securing frontend client, micro-service communication and client-microservice interaction through JSON Web Tokens.

Introduction

Microservices are a great tool when it comes to designing scalable and extensible architectures. They can be used to encapsulate different behaviors or responsibilities in a way that not a lot of other architecture paradigms can represent. And if you pair them with a REST-based interface, then you’re not only writing and creating a platform that can grow and scale automatically (given the right infrastructure of course), but you’re also creating a standard and easy-to-use product.

If you haven’t noticed, I’m a fan of microservices and they’re usually the pattern I go with when designing new architectures, working with Big Data on a day-to-day basis, I tend to require flexibility and scalability out of the box, and they provide that to me.

The thing not everyone considers when writing microservices though is that they require a way for you to authenticate against them. Both if you’re using a front-end client or just communicating with them through another microservice. And although there are several options out there to solve authentication, I want to cover one of the easiest, yet most powerful, alternative: JSON Web Tokens.

JWT-based Authentication

The basic thing you need to understand JWT-based authentication is that you’re dealing with an encrypted JSON which we’ll call “token”. This token has all the information required for the back-end system to understand who you are and if, indeed, you are who you say you are.

How To Set Up Two-Factor Authentication in cPanel

What is 2FA
Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account.
Employing a 2FA mechanism is a vast improvement in security over the Singe-Factor Authentication method of simply employing a username and password. Using this method, accounts that have 2FA enabled, require the user to enter a one-time passcode that is generated by an external application. The 2FA passcode (usually a six-digit number) is required to be input into the passcode field before access is granted. The 2FA input is usually required directly after the username and password are entered by the client.

Angular 9 JWT Login Authentication Example

Tutorial: Angular 9 Login Authentication Example – Angular 9 + SpringBoot + MySQL/PostgreSQL JWT token Authentication
JWT Role Based Authorization with Spring Boot and Angular 9 (Spring Boot Login Example)

JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. So in tutorial ‘JWT Role Based Authorization with Spring Boot and Angular 9 (Spring Boot Login Example)’, I guide you very clearly how to implement full stack example to demonstrade an jwt token based authentication flow from frontend Angular 9 to backend: SpringBoot and MySQL.

– I give you an Epic of the application, a fullstack excutive flow from frontend – Angular 9 to backend – SpringBoot with overall architecture diagram.
– I give you an architecture diagram of SpringBoot security backend.
– I give you a working flow diagram of Angular 9 JWT Application.
– I guide you step by step how to develop a Backend SpringBoot secured RestAPIs with JWT token.
– I guide you step by step how to develop an Angular 9 JWT Token Authentication application.
– Finally, I do an integrative testing from Angular 9 JWT Authentication application to SpringBoot Backend Security RestAPIs.

Angular Spring Boot JWT Authentication example

We will build an application, from frontend (Angular) to backend (Spring Boot), which allows users to register, login account. This application is secured with JWT (JSON Web Token) authentication and Spring Security. Then, depending on the role of current User (user, pm or admin), this system accepts what he can access:

Angular-9-Login-Form

Angular 9 Register Form

Angular 9 Home Page of a User with USER_ROLE

Angular 9 Content Page of a User with USER_ROLE

The diagram below show how our system handles User Registration and User Login processes:

SPRING BOOT BACK-END WITH SPRING SECURITY

This is diagram for SpringBoot Token based authentication Security/JWT classes that are separated into 3 layers:
– HTTP
– Spring Security
– REST API

Spring Boot Security Jwt Token Authentication Architecture Diagram Back End Server

– SecurityContextHolder provides access to the SecurityContext.
– SecurityContext holds the Authentication and possibly request-specific security information.
– Authentication represents the principal which includes GrantedAuthority that reflects the application-wide permissions granted to a principal.
– UserDetails contains necessary information to build an Authentication object from DAOs or other source of security data.
– UserDetailsService helps to create a UserDetails from a String-based username and is usually used by AuthenticationProvider.
– JwtAuthTokenFilter (extends OncePerRequestFilter) pre-processes HTTP request, from Token, create Authentication and populate it to SecurityContext.
– JwtProvider validates, parses token String or generates token String from UserDetails.
– UsernamePasswordAuthenticationToken gets username/password from login Request and combines into an instance of Authentication interface.
– AuthenticationManager uses DaoAuthenticationProvider (with help of UserDetailsService & PasswordEncoder) to validate instance of UsernamePasswordAuthenticationToken, then returns a fully populated Authentication instance on successful authentication.
– SecurityContext is established by calling SecurityContextHolder.getContext().setAuthentication(…​) with returned authentication object above.
– AuthenticationEntryPoint handles AuthenticationException.
– Access to Restful API is protected by HTTPSecurity and authorized with Method Security Expressions.

ANGULAR FRONT-END WITH INTERCEPTOR

In the tutorial, “Angular 9 + Spring Boot JWT Token Based Authentication Example”, we need the Angular HTTP Interceptor to add JWT Token Based for Security authentication:

Angular 9 Jwt Token Workflow Diagram

– app.component is the parent component that contains routerLink and router-outlet for routing. It also has an authority variable as the condition for displaying items on navigation bar.
– user.component, pm.component, admin.component correspond to Angular Components for User Board, PM Board, Admin Board. Each Board uses user.service to access authority data.
– register.component contains User Registration form, submission of the form will call auth.service.
– login.component contains User Login form, submission of the form will call auth.service and token-storage.service.

– user.service gets access to authority data from Server using Angular HttpClient ($http service).
– auth.service handles authentication and signup actions with Server using Angular HttpClient ($http service).
– every HTTP request by $http service will be inspected and transformed before being sent to the Server by auth-interceptor (implements HttpInterceptor).
– auth-interceptor check and get Token from token-storage.service to add the Token to Authorization Header of the HTTP Requests.

– token-storage.service manages Token inside Browser’s sessionStorage.

Overall Jwt Login System Architecture Diagram

Overall Jwt Login System Architecture Diagram

For the Reactjs JWT Authentication tutorial, we have 2 projects:
– Backend project Nodejs/Express provides secured RestAPIs with JWT token.
– Reactjs project will request RestAPIs from Nodejs with the Jwt Token Authentication implementation.

JWT Authentication Sequence Diagram

The diagram below show how our system handles User Registration and User Login processes:

Reactjs Node Jwt Authentication Working Process Diagram

  1. User Registration Phase:
    – User uses a React.js register form to post user’s info (name, username, email, role, password) to Backend API /api/auth/signup.
    – Backend will check the existing users in database and save user’s signup info to database. Finally, It will return a message (successfully or fail) to

  2. User Login Phase:
    – User posts user/password to signin to Backend RestAPI /api/auth/signin.
    – Backend will check the username/password, if it is right, Backend will create and JWT string with secret then return it to Reactjs client.

After signin, user can request secured resources from backend server by adding the JWT token in Authorization Header. For each request, backend will check the JWT signature and then returns back the resources based on user’s registered authorities.

Reactjs JWT Authentication Diagram Overview

Reactjs JWT Authentication Diagram Overview

Reactjs JWT Authentication would be built with 5 main kind blocks:

Reactjs Router is a standard library for routing in React. It enables the navigation among views of various components in a React Application, allows changing the browser URL, and keeps the UI in sync with the URL.
Reactjs Components let you split the UI into independent, reusable pieces, and think about each piece in isolation.
Reactjs Service is a bridge between Reactjs Component and Backend Server, it is used to do technical logic with Backend Server (using Ajax Engine to fetch data from Backend, or using Local Storage to save user login data) and returned a response data to React.js Components
Local Storage allow to save key/value pairs in a web browser. It is a place to save the login user’s info.
Axios – (an Ajax Engine) is a promise-based HTTP client for the browser and Node. js. Axios makes it easy to send asynchronous HTTP requests to REST endpoints and perform CRUD operations.

Jwt Nodejs Token Security RestAPIs Diagram Overview

Jwt Nodejs Token Security RestAPIs Diagram Overview

HTTP request that matches route will be accepted by CORS Middleware before coming to Security layer.

Security layer includes:
– JWT Authentication Middleware: verify SignUp, verify token
– Authorization Middleware: check User’s roles

Main Business Logic Processing interacts with database via Sequelize and send HTTP response (token, user information, data based on roles…) to client.

Project Goal

We create a Reactjs JWT Authentication project as below:

FAQs On a Udemy clone app That You Should Know Before Buying!

BSETEC's Udemy clone app based on formalized teaching but with the help of electronic resources is known as E-learning.E-learning, also referred to as online learning or electronic learning, is the acquisition of knowledge which takes place through electronic technologies .

Udemy, which was founded more than a decade ago, has established itself as a global leader in the online teaching industry. People in our digital era rely on technology and devices for nearly everything, including education. When it comes to online learning, or eLearning, which is regarded as a lifesaver– capable of sustaining the educational environment even during the Covid-19 pandemic– it has evolved into a platform bursting with potential, not only for students but also for tutors, educators, and instructors. Furthermore, when compared to traditional educational techniques, the flexibility and customization given by online tutoring software like Expertplus LMS are unrivalled. As a result, it is gradually becoming an important component of the learning process, which is why eLearning is here to stay– even after the epidemic has passed, it is a huge increase in the number of eLearning applications and websites, and most businesses are choosing for Udemy Clone App instead of starting from scratch.

BigBlueButton Technology – Make Efficient Interaction with LMS

How can I get started with your own online tutoring company?

To use the Udemy Clone App script to establish an online tutoring marketplace similar to Udemy, bear the following factors in mind:

  • How to define your target audience?– Before you start developing your Learning Management System, you should think about who you're going to serve, what their background is, what kind of job they want to do, and what their career goals are. These are all things to consider before you begin the development process. As a result, you must be clear about who you are developing your app for.
  • Why have a clear set of goals and objectives in mind?– If you're creating an app for eLearning, you should have a solid strategy and set of goals in mind. You can't simply take a leap of faith and draw conclusions. You must have both long and short term objectives, and you must put them into action.
  • Why create a simple and speedy registration process?– No one wants to spend more than a minute or two on a signup screen, especially if the app is intended for educational reasons. As a result, it's critical that the user registration, login, and signup procedure be simple and quick. It should provide one-tap or social login options so that the AI can read the social account and fill in the data on its own.
  • Why have a visually appealing homepage– "The first impression is the final impression" and "The last impression is the enduring impression" are two prominent expressions. When you initially open the app, the first thing that appears on your screen is the homepage, and if it isn't appealing enough, you will most likely not want to use it. As a result, the user interface must be simple to use and appealing to the eye.
  • Why do we alter and revise– Once you've begun creating the app, you can customise and revise it to meet the needs of your users, thanks to the Udemy Clone Script's high level of customization and a large range of templates and motifs to select from.


If you want to develop a platform with high-quality eLearning features that cater to the needs of a large mass of audience, then opt for ExpertPlus LMS, and contact BSEtec now! Hurry!

Remote Teams and Good Time Management

This year’s global pandemic has forced the fast adjustment for many organizations from in-office normality to a remote working setup at whiplash speed. The rapid adoption of remote working is not easy though—even without the pressure of COVID.

Challenges are abundant for both those with remote working experience and those without. Managers and team leaders are struggling to keep their teams motivated and efficient. Remote teams are often seen as more difficult to manage, but the tips discussed in this article can help you overcome these challenges.

Empower Remote Team Members

Before digging deeper into time and task management, there are actually several basic steps that you need to complete in order to make remote teams effective. The first thing you want to do is making sure that team members can communicate easily and effectively, and that means establishing a way of communicating that everyone is comfortable with.

Most teams turn to Slack, but Slack is not always the best tool for the job. If your team puts emphasis on project management, for instance, using digital Kanban tools with built-in chat feature can be more effective and other communication tools such as Google Mail with Google Chat and Meet integrations are helpful. Microsoft has a similar suite of tools if you’re inclined to that choice of software.

To further empower team members, integrate a good task management platform. There is no way to keep track of everything when team members have to organize their tasks individually. The easier way to establish a baseline for remote working is by using a project or task management tool that turns tasks into blocks waiting to be managed such as Trello, Asana or Basecamp.

Lastly, encourage team members to create a productive environment that works for them. Some startups and corporations are starting to provide team members with aids to help them set up a more comfortable and functional home office. This is the kind of initiative that puts team members in the right mindset for effective remote working.
