In the era of strong development of technology along with artificial intelligence, face recognition algorithms are more and more accurate and widely applied to life. Researchers began to spend a lot of time studying facial recognition technology. The project building a face authentication system using Face API in the data center system is done through research on how Windows 10 IoT Core operating system works on Raspberry Pi 3 and experimenting with the Face API service toolkit for authentication and face recognition. Since then, the project has brought some results with highly practical applications such as bringing problems from theory to practice, specifically the face recognition door system with the accuracy on the physical door system model to be 90%; which makes opening or closing doors more secure; The product can be applied to the company, enterprise: exit and entrance to data center room, machine room, classroom, office...; Apply facial recognition technology to different purposes easily
