Where did my BAT go?

I reset my computer and reinstalled Brave before anything else. Now I don’t know how to sign back into the browser and reclaim my BAT. It considers me to be a completely new person and it’s presenting me no obvious ways of fixing that.

@Marshmallow unless you have your back-up keys, I’m afraid that you’ll not able to recover it. https://support.brave.com/hc/en-us/articles/360020673191-How-do-I-back-up-or-Restore-my-Wallet-in-Brave-
