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

• Refresh privileges:

flush privileges;

• Try connecting using Node.JS:

If you continue to have problems connecting to the MySQL server after upgrading your client, you can try removing the @'localhost' part from the query in MySQL Workbench. This will allow you to connect to the server without specifying a specific host.

By following these steps, you should be able to resolve the authentication protocol mismatch error and establish a successful connection to your MySQL 8.0 server.
