MySQL 8.0.11 error connect to caching_sha2_password the specified module could not be found

I had the following solution: change my.ini in a [mysqld] section like this:

#default_authentication_plugin=caching_sha2_password  (comment line!)
default_authentication_plugin=mysql_native_password   (new line)

Connect to your MySQL under root in a command line client and execute:

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

Where xxx is your current password.

Try to connect your MySQL use terminal, and use this.

mysql > ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'yourpassword';

See:

Changes in MySQL Workbench 8.0.11 (2018-04-19, Release Candidate)

...

• MySQL Workbench now supports the caching_sha2_password authentication plugin introduced in MySQL 8.0 (see Caching SHA-2 Pluggable Authentication). A user account can be reset to use the other available authentication types for making a connection.
