Biometric data is unique to each individual, therefore biometric technology is often used to identify individuals, giving rise to biometric authentication as a form of identification and access control. Computers can search and store such data in seconds to identify, authenticate, and make decisions on whether or not to allow access.

Today, there are many applications available that use facial recognition software functioning on artificial intelligence (AI) and deep learning technologies, and some even use augmented reality (AR). 

The facial recognition market was estimated at roughly US$5bn in 2021 and is projected to grow to US$12.67bn by 2028. Looking at this growing trend of face recognition software, we take a look at 10 of the top face recognition apps.
