I'm getting ER_NOT_SUPPORTED_AUTH_MODE. Why?

[rivques]

When I try to make a basic connection, it gives me this error:

Error: ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client

My code is

// app.js
const mysql = require('mysql');

// First you need to create a connection to the db
const con = mysql.createConnection({
  host: 'localhost',
  user: 'user',
  password: 'secret'
});

con.connect((err) => {
  if(err){
    throw err;
    }
  console.log('Connection established');
});

con.end((err) => {
  // The connection is terminated gracefully
  // Ensures all previously enqueued queries are still
  // before sending a COM_QUIT packet to the MySQL server.
});

What is your server version? Mysql 8 switched to different default auth mode which is not yet supported by this library.

Possible duplicate of #2002

[rivques]

Mysql server is version 8.0.11.

After looking at a comment on #1962, I can get it to work with what @ruiquelhas has done:

everything should still work if you use the mysql_native_password plugin.

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YourRootPassword';
-- or
CREATE USER 'foo'@'%' IDENTIFIED WITH mysql_native_password BY 'bar';

However, it would be good for it to work without plugins.

It's in progress, see #1962

@rivques Thank you so much! You fixed my bug :)

This line resolve my problem too,

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

Hi Emanuel, Did you run this command on MySql Workbench?
