# MySQL Command-Line Considerations

* If using the MySQL 8.x client, you must pass `--default-auth=mysql_native_password` in your connection string.
* If you also have MySQL installed, the MySQL client may connect to MySQL instead of SingleStore Helios by default if you do not specify the appropriate host and port options. If you attempt to connect to SingleStore Helios on `localhost`, even if you specify the correct port, the MySQL client may still attempt to connect to MySQL with default configuration. See [Network Errors](https://docs.singlestore.com/cloud/reference/troubleshooting-reference/network-errors.md)

For more documentation on the MySQL client, visit the [MySQL documentation](http://dev.mysql.com/doc/refman/5.6/en/mysql.html).
