Whenever I log into my Coinbase crypto account, something very good is that it has the Apple ID thumbprint biometrics data to login. This is good because technically— it is very difficult to hack a fingerprint. I think Face ID is also pretty good.

But the issue is what if your fingerprint scanner, your Face ID scanner whatever is broken or breaks?

One of the good use cases of chainlink I think has to deal with the future of authentication.
