This is why I prefer to use touch id, it's just nice cybersecurity, though it lags sometimes... Nevertheless, I still consider it the most secure, even after reading an article about face recognition https://recfaces.com/articles/face-recognition-apis. Because face recognition has even more issues (like not working when you are wearing a mask, beard, glasses, and so on).
