How do I get my extra key from supporter pack ?

I initially bought the cheapest supporter pack with a key just for myself but have in the mean time upgraded to a pricier pack that should give me an extra key. I would like to give that key to a friend, but I have no idea where to actually find it. I see no message in my message box and also did not receive any emails about it in my linked mailbox.

Thanks for any help/feedback anyone can give.

Thanks ! Found it :-)

WHERE, DUDE??!?!?! ARE YOU SERIOUS?!?!?!! AAAAAHHHHHHHHHHHHHHHHHH
