Unable to load authentication plugin 'caching_sha2_password' [duplicate]

Answer 1

The newer versions of MySQL default to caching_sha2_password. If you want to disable it then follow below steps

1. Login in to your MYSQL console as root user like below.

eg mysql -u YOUR_ROOT_USER_NAME -p YOUR_ROOT_USER_PASSWORD

2. Then execute the command by replacing YOUR_ROOT_USER_NAME and YOUR_ROOT_USER_PASSWORD

ALTER USER 'YOUR_ROOT_USER_NAME'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YOUR_ROOT_USER_PASSWORD';

You will no longer get any 'caching_sha2_password' exception while connecting for any client after this.
