Troubleshooting MySQL 8.0.11 Connection Error: Caching_sha2_Password Issue

MySQL users have encountered an error when attempting to connect to the MySQL server 8.0.11 using MySQL Workbench. The error message: "Cannot connect to MySQL server, authentication plugin: caching_sha2_password: the specified module could not be found" has persisted despite following installation tutorials.

Cause

The issue stems from the default authentication plugin being set to caching_sha2_password, which requires specific procedures for certain versions of MySQL.

Solution

1. Navigate to the my.ini configuration file in your MySQL installation directory and open it.
2. In the [mysqld] section of the my.ini file, locate the default_authentication_plugin directive.
3. Comment out the caching_sha2_password authentication plugin by adding a # symbol at the beginning of the line.
4. Add a new line with the following directive: default_authentication_plugin=mysql_native_password.
5. Save the changes and close the my.ini file.
6. Open a command line client and connect to MySQL as root.
7. Execute the following SQL query: ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'xxx';, where 'xxx' is your current root password.
8. Restart the MySQL service.

Additional Notes

• You may need to disable Caching_SHA2_Password in MySQL on Windows by following additional steps.
• If the error persists, verify that the specified password is correct and that you have sufficient permissions to connect to the MySQL server.
• For further assistance, refer to the MySQL documentation or consult with an experienced MySQL administrator.
