 # Authentication
 
-As outlined in the [gRPC authentication guide](http://www.grpc.io/docs/guides/auth.html) there are a number of different mechanisms for asserting identity between an client and server. We'll present some code-samples here demonstrating how to provide TLS support encryption and identity assertions as well as passing OAuth2 tokens to services that support it.

 ## Defining the service
 
-Our first step (as you'll know from the [quick start](http://www.grpc.io/docs/#quick-start)) is to define the gRPC *service* and the method *request* and *response* types using [protocol buffers](https://developers.google.com/protocol-buffers/docs/overview). You can see the complete .proto file in [examples/route_guide/routeguide/route_guide.proto](https://github.com/grpc/grpc-go/tree/master/examples/route_guide/routeguide/route_guide.proto).
