why expo asking me Apple Team ID?

I am building iOS with Windows. And when Expo asked me to add the path to the P12 file, I added the path but in the next step, the Expo asked me the password for the P12 file but I did not set the password while creating the P12 file. However, when I entered a random password, that password was accepted by Expo. But in the next step, Expo is asking me Apple Team ID. Will I be able to build iOS if I enter Apple Team ID here?
