Implement Passport Authentication with the JWT Strategy
Follow step-by-step instructions to implement the JWT authentication strategy.
In this lesson, we’ll explore how to set up Passport authentication with the JWT strategy in NestJS. It’s a great way to enhance the application’s security and provide a seamless experience for the users.
The JWT strategy
The JWT strategy is an authentication method in Passport that validates users based on JWTs. It allows for stateless authentication because the token contains all necessary information. Stateless refers to the fact that the server doesn’t need to store any information about the user’s session or authentication state on the server itself. All the necessary information to verify the authenticity of the user is contained within the JWT.
We need to install a few dependencies to use Passport and the JWT strategy.
