MySQL 8.0.11连接报错：caching_sha2_password模块未找到求助

Hey there, I’ve run into this exact issue before—let’s get you connected properly. The error pops up because MySQL 8.0.11 switched to using caching_sha2_password as the default authentication plugin, but older versions of MySQL Workbench don’t support this module. Here are two reliable fixes:

方法1：升级MySQL Workbench到最新版本 #

Since MySQL 8.0 introduced the new auth plugin, you’ll need a Workbench version that’s compatible with it (ideally 8.0 or newer). Even if you followed a video step-by-step, the video might have used an older Workbench release. Just grab the latest installer from the official MySQL download page, reinstall it, and this should add the missing caching_sha2_password module to fix the connection.

方法2：修改用户的认证方式为mysql_native_password #

If you don’t want to upgrade Workbench right now, you can adjust your MySQL user to use the older, widely-supported mysql_native_password plugin. Here’s how:

1. Open your terminal/command prompt and log into MySQL via the command line:

   mysql -u root -p
   

   Enter your root password when prompted.
2. Run this SQL command to update your user (replace your_username and your_password with your actual credentials; use localhost for local connections, or % if you need remote access):

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

3. Flush privileges to apply the change immediately:

   FLUSH PRIVILEGES;
   

4. Close and reopen MySQL Workbench, then try connecting again—it should work smoothly now.

Either of these solutions should resolve the "specified module not found" error. Let me know if you hit any snags!
