>> For the server, the default value of the default_authentication_plugin system variable changes from mysql_native_password to caching_sha2_password. 
>>Clients that use an implementation of the client/server protocol other than libmysqlclient may need to be upgraded to a newer version that understands the new authentication plugin. For example, in PHP, MySQL connectivity usually is based on mysqlnd, which currently does not know about caching_sha2_password. Until an updated version of mysqlnd is available, the way to enable PHP clients to connect to MySQL 8.0 is to reconfigure the server to revert to mysql_native_password as the default authentication plugin, as previously discussed. 

so, need implement new default_authentication_plugin (caching_sha2_password).

caching_sha2_password is supported in PHP 7.4.

This is not working for me in PHP 7.4.0 after upgrading, despite what I'm reading everywhere else online. It worked fine in PHP 7.2.8 prior to me upgrading PHP. It seems like PHP is not recognizing caching_sha2_password again.

One person mentioned "possible issues" with mysqlnd in PHP 7.4.0 that could be related, but the link included from it with point 2 doesn't include the same error I have, which is the usual "authentication method unknown to the client" one.

The "possible issues" reference:

When running phpinfo(), mysqlnd also doesn't list caching_sha2_password as one of its authentication plugins, unlike mysql_native_password. Not sure if this is intentional or not, but I figured it was worth noting.

Closing this as caching_sha2_password is in principle supported on 7.4 -- though there are a couple of different bugs that may affect it, tracked at bug #78981 and bug #79011.
