The lesson covers authentication and how it limits access to the cluster to identified clients. Authentication is the process where login accounts and their passwords are verified and the user is allowed access into the database. Authentication is done internally within ScyllaDB and is not done with a third party. Users and passwords are created with roles using a GRANT statement. This procedure enables authentication on the ScyllaDB servers. However, once complete, all clients (application using ScyllaDB/Apache Cassandra drivers) will stop working, until they are updated to work with Authentication as well.
