Right, if you are using MySQL 8.0 series, check [this](https://stackoverflow.com/questions/50373427/node-js-cant-authenticate-to-mysql-8-0/50377944#50377944) as well. — ruiquelhas, Oct 15 '18 at 14:39

Had the same problem.

Install MySQL Workbench

Execute this query: ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456789'; in MySQL Workbench

Head back over to Node.js and try running the file again. It should work, at least it did for me.

In any database software (mysql workbench,datagrip, dbeaver...):

First run this query:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

Second, if your problem still persists, run this query:

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'password';

Combining and running these two queries separately worked for me with dockorize mysql.
