Face ID and identical Twins

Hello,

Just purchased an iPhone 11 pro, which my identical twin's face can unlock the phone. I had heard that that was not possible... any solutions?

Face ID technology is explained in: About Face ID advanced technology - Apple Support

"The probability that a random person in the population could look at your iPhone or iPad Pro and unlock it using Face ID is approximately 1 in 1,000,000 with a single enrolled appearance. As an additional protection, Face ID allows only five unsuccessful match attempts before a passcode is required. The statistical probability is different for twins and siblings that look like you and among children under the age of 13, because their distinct facial features may not have fully developed. If you're concerned about this, we recommend using a passcode to authenticate."
