Authentication¶

Cassandra’s binary protocol supports SASL-based authentication. To enable it, use Cluster.Builder.withCredentials when building your Cluster instance to provide the credentials you wish to authenticate with:

Cluster.builder()
  .withCredentials("bob", "mypassword")
  .build();

This is a shortcut for using PlainTextAuthProvider for simple username/password authentication (intended to work with the server-side PasswordAuthenticator). This may alternatively be provided using the Cluster.Builder.withAuthProvider method:

Cluster.builder()
  .withAuthProvider(new PlainTextAuthProvider("bob", "mypassword"))
  .build();

Authentication must be configured before opening a session, it cannot be changed at runtime.

You can also write your own provider; it must implement AuthProvider.
