Practical GraphQL - Become a GraphQL Ninja - Adding authorisation via GraphQL

The video tutorial explains how to implement token-based authentication in a GraphQL application. It covers storing tokens, creating a function to verify tokens, and integrating this verification into the context of an Apollo server. The tutorial also demonstrates how to use the Me object in resolvers to ensure only authenticated users can perform certain actions, such as creating a car. Finally, it includes testing and debugging the implementation to ensure it works correctly.
