Auth0 is an alternative way to authenticate the users, and it is not required since Chaskiq has its own auth system. Anyway, if you want to configure Auth0 in Chaskiq use the following env variables in order to activate auth0

AUTH0_ENABLED=false
AUTH0_CLIENT_ID=xxxx
AUTH0_CLIENT_SECRET=xxxx
AUTH0_DOMAIN=yourdomain.us.auth0.com
AUTH0_AUDIENCE=https://yourdomain.us.auth0.com/api/v2/

You must use the /api/v2 endpoint, put your own domain.
