Why is MySQL Showing 'Authentication plugin 'caching_sha2_password' is not supported' and How Can I Fix It?

How to Resolve the "Authentication plugin 'caching_sha2_password' is not supported" Error

When connecting to a MySQL server using the Python connector, users may encounter the error: "Authentication plugin 'caching_sha2_password' is not supported." This issue arises when attempting to connect with the mysql_native_password authentication plugin.

One potential solution is to install the correct connector module. Make sure to install mysql-connector-python instead of mysql-connector via pip3. This will provide the necessary functionality for connecting with the desired authentication plugin.

Here's a modified code snippet that includes the explicit auth_plugin parameter:

import mysql.connector

cnx = mysql.connector.connect(user='lcherukuri', password='password',
                              host='127.0.0.1',
                              database='test',
                              auth_plugin='mysql_native_password')
cnx.close()

By specifying auth_plugin='mysql_native_password', the connection will attempt to use the correct authentication method and resolve the "Authentication plugin 'caching_sha2_password' is not supported" error.
