Error: Client Does Not Support Authentication Protocol Requested by Server; Consider Upgrading MySQL Client

MySQL 8.0 - Client does not support authentication protocol requested by server; consider upgrading MySQL client

Execute the following query in MYSQL Workbench

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

Where root as your user
localhost as your URL
and password as your password

Then run this query to refresh privileges:

flush privileges;

Try connecting using node after you do so.

If that doesn't work, try it without @'localhost' part.

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.

ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client on visual studio code

I had the same problem. in order to solve it, try to use on your MySQL client:

ALTER USER '<your_user>'@'localhost' IDENTIFIED WITH mysql_native_password BY '<your_password>'

Like this:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '1234'

Then try the connection again no VS Code! That solved for me.

Client does not support authentication protocol requested by server; consider upgrading MySQL client even after downgrading to mysql@5.7

MySQL 8.0 introduced a default SHA256 encryption that many clients do not understand. You have many options, the easiest being using the older MySQL native password (see https://mysqlserverteam.com/upgrading-to-mysql-8-0-default-authentication-plugin-considerations/) authentication. Change the account to use the older authentication and your client connector will be happy.

Node JS and mysql not connecting (client does not support authentication protocol requested by server consider upgrading mysql client)

Instead of

mysqlConnection.connect((err) => {

use

connection.connect((err) => {

if(!err)
    console.log('Database is connected!');
else
    console.log('Database not connected! : '+ JSON.stringify(err, undefined,2));
});

[Here the is tutorials reference for the code]1

For your mysql error:

Execute the following query in MYSQL Workbench:

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

Try connecting using node after you do so.

ER_NOT_SUPPORTED_AUTH_MODE issue with Keira3

Unfortunately the mysql library used by Keira3 does not support the new Mysql 8.0 authentication protocol, to change it you can run:

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

There is an open issue for this problem.
