Fix PHPMyAdmin Error: requested authentication method unknown to the client [caching_sha2_password]

While installing PHPMyAdmin on your Mac OS, you might encounter the following error:

Alt Text

mysqli_real_connect(): The server requested authentication method unknown to the client [caching_sha2_password]
mysqli_real_connect(): (HY000/2054): The server requested authentication method unknown to the client
Enter fullscreen mode Exit fullscreen mode

This error happens because of the change in authentication in the later MySQL versions.

This is how to solve the above error:

  1. Make sure your MySQL Server is running

Alt Text

  1. From your terminal, login to MySQL:

sudo /usr/local/mysql/bin/mysql -u root -p

Enter the password you used to setup MySQL

  1. Run the below command from MySQL shell:

ALTER USER 'user'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

OR

ALTER USER root IDENTIFIED WITH mysql_native_password BY 'password';

Replace user and password with your actual values.

Have you tried ServBay.dev?
It's a much easier tool for PHP developers, providing a user-friendly experience, especially for beginners. It supports all versions of PHP, MariaDB, PostgreSQL, as well as Redis and Memcached. You can run multiple PHP instances simultaneously and switch between them effortlessly. It also offers easy updates without the need to configure environment variables. This tool has greatly simplified my PHP development and is definitely worth trying!

Hello Kelvin,
Thank you for the fix, I found out that the user needs to run the command flush privileges; after performing the ALTER operation, or just restarting the MySQL server.
