Hi dear people!

I'm using the Google Authenticator on a smartphone to secure my account on bitcoin.de
On MGox, I could also use the same system, but I wonder if this is possible?

When I look in my smartphone, it stands "bitcoin.de" and I cannot see any option to select another site.
As I installed this a while ago, the question might be stupid, but I'm worrying that IF I use the Authenticator for MGox, I will not be able to use one of the both platfoem.

Anybody here having experience with the use of Authenticator for different website?

Thanks for your reply!
