Actually I can't fix this issue. Both mysql node libs (mysqljs/mysql#1962) are not supporting this authentication.

I suggest you to try this SO answer for now:
https://stackoverflow.com/a/51918364

Let me know if it worked for you, but my hands are tied til' they merge this PR.

The temporary fix suggested on StackOverflow works!

I just make a donation to the project as well.

Thanks.

I would like to point out that if you are using PHP's PDO or mysqli_connect function and you're on PHP version 7.1, those utilities are already using the new caching_sha2_password plugin, which means that if you use the same username for php scripts and for the SQLTools extension, you're gonna have a bad time trying to connect to your site via localhost. According to this Russian post on Medium, you should have a user account for accessing mysql via workbench, cli, or through extensions like this one, and a separate account for PHP 7.1 scripts that use PDO or any other kinds of scripts that use the new plugin exclusively.

@ntt2k I'll be closing this for now since I can't work on it till the 3rd party libs fixes this issue.

Feel free to reopen it whenever you want, ok?

Thanks!

Also, thank you @OzzyTheGiant for this well explained comment. Sure it will help 👏👏
