Not finished set up need to reset password macbook pro

I recently purchased the newer MacBook pro M2 chip, don't know what info needed to help with a solution for me, but I have always had the worst memory ever. Though I have written it down it didn't work and any variation of the password didn't work and I think I may have typed something wrong thinking I was typing what I had written down. At this point I already know I don't deserve to set eyes on apple products because I'm a serial password forgetter, but if anyone has any advice for me I would so appreciate it. I only partially started setting it up I wasn't able to get apple ID info set up because I was at work it got busy and when I finally got back to it well "access denied". She still has that new car smell still in the box.

Anyway thanks for taking the time if there is even a solution for my carelessness.
