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 - loizenai.com

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.

Python Packages in SQL Server – Get Started with SQL Server Machine Learning Services

Introduction

When installing Machine Learning Services in SQL Server by default few Python Packages are installed. In this article, we will have a look on how to get those installed python package information.

Python Packages

When we choose Python as Machine Learning Service during installation, the following packages are installed in SQL Server,

  • revoscalepy – This Microsoft Python package is used for remote compute contexts, streaming, parallel execution of rx functions for data import and transformation, modeling, visualization, and analysis.
  • microsoftml – This is another Microsoft Python package which adds machine learning algorithms in Python.
  • Anaconda 4.2 – Anaconda is an opensource Python package

React Node Jwt Authentication without Redux - using LocalStorage and Axios

https://loizenai.com/react-node-jwt-authentication/

React Node Jwt Authentication without Redux

Tutorial: React Node Jwt Authentication (without Redux) – using LocalStorage and Axios (plus interceptor) in React application and Express + Sequelize + MySQL/PostgreSQL in Nodejs backend solution.

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. And “How to build Reactjs Nodejs Jwt Token Based Authentication Example?” is one of the most common questions for SpringBoot Java development world. So in the tutorial, I introduce how to implement an application “Reactjs JWT SpringBoot token Authentication Example” with details step by step and 100% running sourcecode.

– I give you an Epic of the application, a fullstack excutive flow from frontend (Reactjs) to backend (Nodejs/Express) to database (MySQL/PostgreSQL) with overall architecture diagram.
– I give you a layer diagram of Reactjs Jwt Application with LocalStorage and Axios (plus Interceptor)
– I guide you detail-steps how to implement a security Jwt Token Nodejs backend.
– I guide you step by step how to develop a Reactjs Jwt Authentication application.
– Finally, I do an integrative testing from Reactjs Jwt Authentication application to jwt Nodejs Security RestAPIs.

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:

Project Structure

It includes 8 components and 2 services and a router in app.js file.
