Cannot Connect to MySQL Server: Caching_sha2_Password Plugin Missing

Attempts to establish a connection with MySQL server 8.0.11 from MySQL Workbench have encountered a persistent error: "Cannot connect to MySQL server, authentication plugin: caching_sha2_password: the specified module could not be found."

An Explanation of the Error

The error message indicates that the MySQL server is unable to locate the caching_sha2_password authentication plugin, which is required for secure authentication protocols. This plugin ensures the secure storage and verification of user passwords.

Resolution

To resolve this issue, follow these steps:

1. Locate your MySQL configuration file (my.ini or my.cnf) and navigate to the [mysqld] section.

2. Comment out or remove the following line:

   #default_authentication_plugin=caching_sha2_password

3. Add the following line to the [mysqld] section:

   default_authentication_plugin=mysql_native_password

4. Save the configuration file and restart the MySQL server.
5. Once the server is running, connect to the MySQL database as the root user using a command-line client.

6. Execute the following query:

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

   Replace 'xxx' with your current root password.

7. Retry connecting to the MySQL server from MySQL Workbench or other clients. The error should no longer occur.
