The driver supports user ID/password and Kerberos authentication with the AuthenticationMethod connection property.

When AuthenticationMethod=userIdPassword (default), the driver uses SCRAM-SHA-1 user ID/password authentication. The User property provides the user ID, and the Password property provides the password.

When AuthenticationMethod=kerberos, the driver uses Kerberos authentication.

Note: The userIdPassword setting is appropriate for servers that do not have authentication enabled. In a scenario where AuthenticationMethod has been set to userIdPassword but the server has not been configured for user ID/password authentication, the driver will still connect to the database server.
