Authentication and Authorization
Explore strategies for authenticating clients and authorizing access to gRPC service methods.
Secure Your gRPC Services
Welcome! In this lesson, we'll dive into Authentication and Authorization for gRPC services. These are crucial concepts for building secure and reliable distributed systems.
You'll learn how to verify who is accessing your services and what actions they are allowed to perform.
Authentication: Who Are You?
Authentication is the process of verifying a client's identity. Think of it like checking an ID at a club.
- It answers the question: "Are you who you say you are?"
- Common methods include API keys, JWTs (JSON Web Tokens), or OAuth tokens.
- In gRPC, these credentials are often passed as custom metadata with each request.
