Because the in-display ultrasound fingerprint reader on Galaxy S20 ( and S10) is hard to use and is slow, many Galaxy S20 owners have to use face recognition to unlock the phone and find that face recognition (face unlock) is faster than the fingerprint.
This Galaxy S20 guide explains what Galaxy S20 face recognition is, how to use and manage face recognition to unlock Galaxy S20, how to register your facial features for face unlock, and limitations of Galaxy S20 face recognition.
Galaxy S20 face recognition (face unlock) works identically on Galaxy S20, S20+, and S20 Ultra. So this guide applies to all of these three models.

In recent releases, Android has greatly improved facial recognition. It is fast enough so that you do not need to wait too long. It is accurate enough so that you cannot cheat it with a photo.
Of course, the face unlock on all Android phones is still considered as “less” secure than the fingerprint.
When Samsung ditched the iris scanner (and the intelligent scan), Samsung did NOT add an IR camera. So, on Galaxy S20, face unlock purely relies on the selfie camera. It is NOT comparable to Apple Face ID.
You may consider the Galaxy S20 facial recognition if you need an alternative to the inferior in-display fingerprint scanner.
