Problem with new MySQL Workbench connection
Since you get an "access denied" the actual connection to the server worked. You just have used a user that is not allowed to connect either because it connects from a machine that is not enabled in the user settings and/or the user does not exist or the password is wrong. 


Is it the correct server you connected to?
Are you 100% sure to have used the right user/pw? 
Is the IP address of the user allowed to connect at all?
