MAC address Randomization

Hello! I wanted to exchange some ideas on the impact we will all have on the MAC address randomization being implemented as an enabled by default feature on iOS14 Apple Devices (https://support.apple.com/en-us/HT211227). Some authentication procedures on our networks are based on the MAC address so I think the impact is going to be huge and certainly, analytics and accounting will be impacted as well. ¿What are your thoughts on this? ¿What are some workarounds we should implement? ¿are there any?
