Fix "Invalid Authentication Plugin" mysql_native_password Error in MySQL (Workbench, PHP, Connector)
If you're getting the “Invalid Authentication Plugin” error while connecting to your MySQL server — whether through MySQL Workbench, PHP, or any other database connector — this video will show you how to fix it properly.
This issue occurs when a MySQL user is configured to use an unsupported or disabled authentication plugin (like mysql_native_password), causing clients to fail authentication even with the correct username and password.
In this video, you’ll learn how to:
Identify the user’s current authentication plugin
Understand why the error happens
Switch to the supported caching_sha2_password plugin
Reload privileges and verify the fix
Once done, you can reconnect successfully from MySQL Workbench, PHP applications, or any other MySQL client.
