Apple ID password change not working, can’t login to mac

A few hours ago, i was gifted a macbook pro by a family member. It has been used before, but it was formatted for me to use.

When setting up, I assume i made a mistake in setting my laptop password as the one I intended to set isn’t working.

To fix this I tried to change it by logging into my Apple ID, but my password wasn’t working for it. It was the same password I use for everything and worked on other devices. I changed it multiple times, but it never worked.

I didn’t change it online, and I have tried booting into safe mode, but it hasn’t fixed anything. What is left for me to do? How can I fix this?

I am relatively new to using Macbook devices, so I might be doing something wrong or stupid. Please let me know!
