Go (Golang) JWT Authentication Tutorial

Go (Golang) JWT Authentication Tutorial

In this episode we are going to implement JWT authentication for an endpoint in our JSON REST APIs which we have seen in our previous episode 👉 https://www.youtube.com/watch?v=8S30eoBSojU

We are going to:

  • See how the JWT is structured (header, payload, signature)
  • Different Algorithms that can be used (HMAC-based, RSA, ECDSA)
  • Implement a “auth” endpoint which generates a JWT
  • Implement a “authorizer” handler which verifies a provided JWT token and ensures only authenticated users can access that handler

JWT is a fantastic standard that allows us to verify users (or anything for that matter) in a stateless way. Once the user has been firstly identifier and issued a token, any further request coming from the user carrying the JWT token will be verified without having to check the database or any other authentication system, we can just verify the authenticity of the token to verify the user.

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.

Build Golang with JWT Authentication Server

JWT Authentication for GO, using Gin-Gonic and MongoDB. Finally, in this project we will build golang with JWT authentication server. We will use gin-gonic to build the APIs and mongodb to store the users.

Anatomy of Conditional Statements and Loops in Go

Go provides if/else and switch conditional statements for code execution based on certain conditions. To execute some code over and over again, we have the for loop.

The if/else conditional statement

Go provides if, if-else, if-else if-else variants of if/else statement we are familiar with. It is used to check a condition, and execute some code when the condition is true or false.

The if condition

Simple use of if condition is demonstrated below. Unlike most of the programming languages, Go does not allow to wrap the condition inside parenthesis ().
