How Can I Quickly Fix the MySQL 'Access Denied for user 'root'@'localhost'' Error?

Solving the MySQL "Access Denied" Error for the 'root' User

The common MySQL error "Access denied for user 'root'@'localhost' (using password: YES)" often leads users down a rabbit hole of complicated solutions. Fortunately, a simple fix usually works.

Instead of complex troubleshooting, try this single query executed via sudo mysql:

<code class="language-sql">ALTER USER 'root'@'localhost' 
IDENTIFIED WITH mysql_native_password 
BY 'root';

(Or, for MariaDB:)

ALTER USER 'root'@'localhost' 
IDENTIFIED VIA mysql_native_password 
USING PASSWORD('root');</code>

This query performs two key functions:

• Changes the authentication plugin: It switches to the mysql_native_password plugin.
• Sets the root password: It sets the password to "root" (remember to replace 'root' with your chosen password within the query).

After running this query, you should be able to access your database as the root user. Consult the official MySQL or MariaDB documentation for further information.

To exit the MySQL console, press Ctrl D or type "exit".
