Auth Token is a JWT Token generated based on the logged-in user. By default, the token is only valid for 10 hours. However, you can change the value by defining it using environment variable `NC_JWT_EXPIRES_IN`. If you are passing Auth Token, make sure that the header is called `xc-auth`.
API tokens allows us to integrate seamlessly with 3rd party apps. See [API Tokens Management](../setup-and-usages/team-and-auth#api-tokens-management) for more.
