Can’t remove security key from Windows 10

Hi

I have been getting in my PC after boot up or trying to unlock it that primary sign in option is Security Key

I have never used or set up this as I only use traditional password.

I have been unable to remove this option from the Sign in Options and no idea why it started to appear as i have never set up one

On windows 10 in Accounts > sign-in options, it shows the Security Key option as setup.

When I click “Manage” to try and remove it, it says “insert security key into the USB port” so we are in a loop as i have never set up one

How can i remove this option from my Sign in to my Windows PC?
