Authentication plugin "caching_sha2_password" cannot be loaded

🛠️ How to Fix "Authentication plugin 'caching_sha2_password' cannot be loaded" Error in MySQL 8.0 🚫🔌

If you're trying to connect MySQL 8.0 with MySQL Workbench or any other client tool, and you encounter the frustrating "Authentication plugin 'caching_sha2_password' cannot be loaded" error, fear not! We've got you covered with easy solutions and workarounds.

💡 Understanding the Issue

💔 This error occurs because MySQL 8.0 uses a new default authentication method called caching_sha2_password, which is not supported by older client tools that use the older mysql_native_password authentication method.

🤔 In simpler terms, when you're trying to connect from a client tool that doesn't support the new authentication method, MySQL refuses to load the required plugin and throws the error.

🔎 Common Solutions

Here are a few common solutions to fix this error:

1. Upgrade your Client Tool

✅ The easiest solution is to upgrade your client tool to a version that supports the caching_sha2_password authentication method.

😎 For instance, make sure you're using the latest version of MySQL Workbench. They provide frequent updates, which often include support for the latest MySQL features.

2. Downgrade the Authentication Method

⚠️ Be cautious when using this solution as it involves lowering the security level of your MySQL authentication.

🔧 To change the authentication method from caching_sha2_password to mysql_native_password, follow these steps:

1. Log in to your MySQL server using a client tool that supports the mysql_native_password authentication method.

2. Run the following SQL query to change the authentication method for the user you're trying to connect with:

   ALTER USER 'your_username'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_password';

   ℹ️ Replace 'your_username' and 'your_password' with the actual username and password you're using to connect.

3. Finally, run FLUSH PRIVILEGES; to apply the changes.

4. Retry your connection from the client tool that previously threw the error. It should work seamlessly now.

🚨 Note: Downgrading the authentication method can introduce security risks, so it's essential to evaluate the potential impact before implementing this solution.
