PHP 7.2.2 + mysql 8.0 PDO gives: authentication method unknown to the client [caching_sha2_password] [duplicate]

Answer 1

Found this somewhere, don't remember where (or I would credit), but it works for me until MySQL 8 gets better.

In MySQL shell (command prompt, whatever):

CREATE USER username@localhost identified with mysql_native_password by 'password';

Where username is the username and password is the password for that user.

Then you can add permissions in the shell - or in the Workbench as the user now exists with Authentication Type: Standard.

Answer 2

If you want to use MySQL >= 8 and you don't care about caching_sha2_password, just select the second option when you install.

Answer 3

In order to use mySQL 8 (with the new authentication method) you could just upgrade your PHP.

MySQL 8

When running a PHP version before 7.1.16, or PHP 7.2 before 7.2.4, set MySQL 8 Server's default password plugin to mysql_native_password or else you will see errors similar to The server requested authentication method unknown to the client [caching_sha2_password] even when caching_sha2_password is not used.

Answer 4

alter user 'username'@'localhost' identified with mysql_native_password by 'password';
