How Can I Fix Node.js Authentication Errors with MySQL 8.0\'s caching_sha2_password?

Node.js Authentication Issue with MySQL 8.0

The recent upgrade to MySQL 8.0 has introduced an authentication challenge for Node.js applications connecting to MySQL databases. MySQL 8.0 employs a new default authentication plugin, caching_sha2_password, which the current community Node.js drivers for MySQL lack compatible client-side authentication mechanisms to support.

Problem:

Node.js applications are unable to authenticate successfully to MySQL 8.0 databases, resulting in an "ER_NOT_SUPPORTED_AUTH_MODE" error during authentication due to the mismatch in authentication plugins.

Workaround:

To circumvent this issue, you have two options:

1. Alter the User Account's Authentication Plugin:

   Modify the existing 'root' user account or create a new user account to use the previous authentication plugin, mysql_native_password. This can be achieved through the following SQL commands:

   ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'MyNewPass';
   
   CREATE USER 'foo'@'localhost' IDENTIFIED WITH mysql_native_password BY 'bar';

2. Use the Official MySQL Node.js Connector:

   Utilize the official MySQL Node.js connector, which is based on the X Protocol and natively supports the new authentication mode used by MySQL 8.0.

Future Resolution:

A pull request is currently in development to address this issue in the community Node.js drivers for MySQL. Once merged and released, this update will provide proper support for the new authentication mode in MySQL 8.0.
