How to get back whatsapp account

[AC Question]

I have recently factory/hard reset my phone. Apparently the Whatsapp application doesn't exist in my phone anymore. When I reinstall the app and opened it, I had to sign up. Does this mean my account is deleted and I have to make a new one or is there a way to get it back?

Hi, when you download the app it will allow you to sign in not just sign up.
