MySQL Administrator Login Error

[AndrewMcHorney]

Hello

I tried to login using localhost and root as user id with no password 
since I temporarily did not enter one when I installed the software. 
I am getting the following error message:

MySQL Error Number 1045
Access denied for user 'root@localhost' (using password:NO)

The port select is 3036.

What does this error mean?
