>             Project: Cassandra
>          Issue Type: Improvement

> Currently gocql will only allow authenticating with authenticators defined in {{defaultApprovedAuthenticators}} in {{conn.go}}.
> There have been multiple occurrences of implementers needing to update this list, either when a vendor would like to add their authenticator, or a new authenticator being added, e.g.: [CASSANDRA-19858]
> examples:
> https://github.com/apache/cassandra-gocql-driver/pull/883
> https://github.com/apache/cassandra-gocql-driver/pull/1254
> https://github.com/apache/cassandra-gocql-driver/pull/1321
> https://github.com/apache/cassandra-gocql-driver/pull/1379
> I think it would probably reduce friction to just accept any authenticator provided by the server.  From what I know, other drivers behave in this way.
> If a user wanted to restrict this, they could use the existing configuration {{PasswordAuthenticator.AllowedAuthenticators}}, e.g.:
> {code}
> cluster.Authenticator = PasswordAuthenticator{
>     Username: x,
>     Password: x,
>     AllowedAuthenticators: []string { 
>         "myrandomauth",
>     }
> }
> {code}
