Steam co-op connection?

I have two computers with portal 2( same steam account). Can I play coop with my brother, even though It is one steam account?

P.s. I do not care if I have to use console commands or an Ethernet cable.

    Yes, via LAN.

    Start with the guest machine (this machine will play P-body, the orange robot):

    Launch Steam in offline mode.

    Start Portal 2.

    Enable the developer console (under advanced keyboard options). This only has to be done once.

    Enter the developer console by pressing the back-quote (`) key, to the left of the number 1.

    Now, on the host machine (this machine will play Atlas, the blue robot):

    Launch Steam in online mode.

    Start Portal 2.

    Enable the developer console (again, this only needs to be done the first time).

    Select "Play cooperative game" from the main menu.

    Select "Standard co-op"

    Wait for the "Invite friends" page to appear. It's okay if the page is empty.

    Enter the developer console by pressing the back-quote (`) key.

    Type sv_lan 1

    Back on the guest machine:

    Type connect (IP address of host machine)

    And then on the host:

    Type map mp_coop_start (for the calibration level, if you haven't played before), or map mp_coop_lobby_2 (for the hub)

    You may need this info too in order to load maps:
