+# Authentication configuration for receivers
+
+This module allows server types, such as gRPC and HTTP, to be configured to perform authentication for requests and/or RPCs. Each server type is responsible for getting the request/RPC metadata and passing down to the authenticator. Currently, only bearer token authentication is supported, although the module is ready to accept new authenticators.
+
+Examples:
+```yaml
+receivers:
+  somereceiver:
+    grpc:
+      authentication:
+        attribute: authorization
+        oidc:
+          issuer_url: https://auth.example.com/
+          issuer_ca_path: /etc/pki/tls/cert.pem
+          client_id: my-oidc-client
+          username_claim: email
+```
