Put simply, it is generally a good idea to log out of your account when you switch between computers/networks. Provided that those public wifi are trustworthy in general DMM generally doesn't care. Mind you however, if the IP you're using on a shared/public connection that has other users using it to get into DMM you may have to change your password for security purposes.
