Facebook fake account?

[Zak]

Hi,
so for a school project I am supposed to make a Facebook page of a historical figure, including messages with other historical figures and photos and everything. But since I have my own Facebook that I check, I often log myself out of my project to check my real Facebook. Every time I log back on, Facebook says that my account is probably fake and always asks for my phone number, which I type in and receive a confirmation code. Each time, it is a different confirmation code that I must go on to my phone to find and type it in on my computer. since this is extremely annoying, what steps can I take to ensure that Facebook doesn't continue making me confirm everything each time i log on???
