$ mysqladmin -u root -p'cwY+nbtxt3w' password newpass
Old password is a temporary password by MySQL (in the screenshot below). MySQL is running in settings.
Get errors and warnings :
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: YES)'
Can you explain how to deal with that?
