Played about 4 years ago. I want to restart but can't log in.

I had to use a different method to set up right now and am not as tech saavy as I use to be. I can't really tell if I have just done something wrong, or if my account no longer exists?

I followed a guide online (https://www.youtube.com/watch?v=mj_MMVgJ_Dk&t=161s) but I receive an incorrect password message.

I guess I'm just curious if my account is still active or if the steps in this guide are bad?
