authenticationPlugins defines a comma-delimited list of classes that implement com.mysql.jdbc.AuthenticationPlugin and are used for authentication unless disabled by the disabledAuthenticationPlugins property.

disabledAuthenticationPlugins defines a comma-delimited list of classes implementing com.mysql.jdbc.AuthenticationPlugin or mechanisms, i.e. mysql_native_password. The authentication plugins or mechanisms cannot be used for authentication. Authentication will fail if it requires one of these classes. It is an error to disable the default authentication plugin, either the one named by defaultAuthenticationPlugin property or the hardcoded one if defaultAuthenticationPlugin property is not set.

defaultAuthenticationPlugin defines the name of a class implementing com.mysql.jdbc.AuthenticationPlugin, which is used as the default authentication plugin. It is an error to use a class that is not listed in authenticationPlugins and is not one of the built-in plugins. It is an error to set as default a plugin that is disabled by being listed in the disabledAuthenticationPlugins property. It is an error to set this value to null or the empty string; there must be at least one valid default authentication plugin specified for the connection, meeting all the constraints listed above.
