Quick Google Authenticator tip

Do you use two factor authentication on your Google account? No? You should! 

I have a simple tip. If you use multiple iOS devices, you can install the authenticator on all of them. Have them all with you when you set up, and you'll have a second device to give you your code when the first one is lost/out for repair like my iPhone was.

Just scan the barcode with both devices before you fill in the confirmation field.
