How Can Node.js Applications Authenticate with MySQL 8.0\'s Caching SHA2 Password?

Node.js Authentication Issues Connecting to MySQL 8.0

MySQL 8.0 introduces a new authentication mechanism that poses difficulties for Node.js programs connecting to the database. The legacy authentication method used in previous MySQL versions is no longer supported by default.

Authentication Mechanism Discrepancy

MySQL 5.7 employed the mysql_native_password plugin for authentication, while MySQL 8.0 utilizes caching_sha2_password. The Node.js community drivers currently lack compatible mechanisms for the newer plugin.

Workarounds for Node.js

To circumvent this issue, there are two potential workarounds:

• Reverting to the Legacy Plugin:

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

This modifies the root account to use the old authentication method.

• Creating a New User with the Legacy Plugin:

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

This creates a separate user with the legacy plugin.

Alternative Option Using MySQL Connector

Another solution involves using the official MySQL Node.js connector. This connector leverages the X Protocol and supports the newer authentication mechanism out of the box.

Community Support and Updates

There is an upcoming pull request that aims to address this issue within the community Node.js drivers. However, updates are expected to take some time.
