Incard

Introduction:

I was tasked with building a web application to manage basic authentication. To meet this requirement, I opted to use Next.js and TypeScript, ensuring support for both server-side and client-side rendering and strong typing.

Authentication and session management were implemented using NextAuth library, utilizing JWT tokens with a maximum age of 3 minutes, users can renew their tokens with a single click; however, if the time elapses, they will prompted to reauthenticate.

Notably, the application's UI matches that of InCard.

[!NOTE]

For Authentication you can use the following for both username and password:
