Windows 10: How to sign in on my old laptop as I am not receiving a code to my active Microsoft email?

I had an old laptop in storage that I took out and began updating Windows. The last update for Windows 10 now asks me to receive a code from Microsoft to my current Hotmail account. I was able to use a password to sign in several times before, but that option is no longer available. Do you have any recommendations? I only see four options available to click; the wifi icon, the power icon, and the accesability, in addition to the sign in Yes, I have checked multiple folders in my email; inbox, spam, other, and have searched for a code. I'm not sure an email was sent from the computer it show'
