To date, Android phone makers who've wanted to include face recognition have had to craft their own secure solutions or else use basic face detection that you can fool with a photo. Soon, however, it might be relatively commonplace. Sleuthers at XDA and 9to5Google have discovered code in an early Android Q version that hints at native support for hardware face recognition. It wouldn't just be used for signing into your phone, either, as it could also authorize purchases and sign into apps. It would largely be a parallel to the Face ID system found in Apple's more recent iPhones, just with more flexibility.
