ER_NOT_SUPPORTED_AUTH_MODE - MySQL server

Question

I have setup a MySQL database. When I try to access it through my Node JS server, I am getting the error

\"ER_NOT_SUPPORTED_AUTH_MODE: Client does no

Answer 1

var connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'root',
  password : '********',
  database : 'vod_bill_database',
  port : 3308 
}); 

I had the same error and since i changed my port in phpmyadmin from 3306 to 3308 therefore here also i had to write port: 3308 and it started working.

// mysql.ts
const pool = mysql.createPool({
    connectionLimit: 10,

    expose:
      - '3306'
    volumes:
      - my-db:/var/lib/mysql2
volumes:
  my-db:

Answer 6

I figured that in some MySQL versions they have the authentication for the establishment of a connection a bit messed. All I had to do was add the line "insecureAuth : true" to my connection attempt.

var connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'root',
  password : '********',
  database : 'vod_bill_database',
  insecureAuth : true
}); 

It is working fine now.
