My apple ID is not letting me login on my computer

So, I have an iPhone 6 and Macbook Pro and on both of my devices I was logged into my Apple ID. But, of course I forgot my password and I tried to reset it. I have managed to login on my iPhone with my new Apple ID but, for some reason it is not working on my Macbook. Any clue as to why? I could use any little of bit of help possible.
