Feature: Remix the authentication using JWT and to enable logged in users view saved code snippets.

Feature description

Currently, the authentication is bare minimum and not secured to brim. I want to use JWT's and make a after login flow where the already logged in users can see their previously saved code snippets, just a inspiration from codepen!
