The preferred auth plugin for this version is caching_sha2_password. And the user was able to log in to PHPMyAdmin successfully.īut this is a temporary fix as the MySQL 8 uses PHP 7.0. If the database user is not root user, replace the username and password respectively.įinally, this fixed the error. Here we replaced the ‘ password‘ with the password of the root user.

If the names don’t match, it checks for the socket username of the er. Whereas the auth_socket plugin checks if the socket username matches with the MySQL username. The caching_sha2_password plugin uses an SHA-2 algorithm with 256-bit password encryption. MySQL uses caching_sha2_password and auth_socket plugins for validation. The server validates the user and returns the connection status. How does the MySQL server authenticate a client?Ī PHP application connects to the MySQL server using the username provided by the server/hosting provider. Today, let’s see how our Support Engineers fix this error. Īt Bobcares, we often get requests to fix MySQL errors, as a part of our Server Management Services.
