Correct syntax for MySQL options?

Hello everyone, is the following the proper syntax to designate an authentication plugin?:

authenticationPlugin=MysqlNativePasswordPlugin;

I was just wondering because I am getting an unable to load authentication plugin when I try to connect to a secure DB so I thought I would try to designate which plugin was used. I have been informed that our DB allows for the old and new hashing styles and therefore should allow a request for a connection using the native password style.
