My account had *2-step verification* enabled and associated with the Authenticator App on my phone. 

Yesterday I reformatted it and now I'm installing the apps again. Everything is setup but the Google Authenticator App looks for a barcode, and I cannot find in the *2-step verification* steps. What I'd like to do is re-associate my account with the Google Authenticator App **without** turning off 2 step auth and back on again. 

Any ideas?
