Snapchat and Google Authentication app

So, I had a Galaxy S6 and I downloaded the google authentication app. But, just today I bough an S7 and I lost my authentication codes on my Google Authentication app, meaning I can't log back onto Snapchat. Is there any way I can reset this feature similar to how I can reset a password or any way of getting back into it? I also don't think I have a recovery code
