My passkey no longer works?

Aloha my fellow Steemians,

I just bought a new laptop with a dedicated graphics card so I can launch Kahuna Organics DTube channel! I tried to log into steemit on my new laptop and my passcode does not work!:-(

Back when I joined in January,I followed the warnings and directions, and copied and pasted on 2 flash drives and made a written copy! I even used the pass code to log on to my computer multiple times, so I know it has worked in the past, I set both my phone and old laptop

to remember me to stay logged in, an No one has had access to my laptop?

So, I'm not sure what happened since the last time I logged in a few months ago, to last night trying to log into my laptop?

Does anyone have any ideas or suggestions of what might have caused this to happened, and is there any way to get my new PC signed into steemit without creating a new profile! This is my business ID f
or Twitter and Steemit!

Since my original passcode is invalid, I can't change the password, and if I ever log out of my phone, like I did my old laptop this morning, I will never be able to log back into KO Kahuna!

Mahalo for your help!
Michael
