As more and more things are moving online, two problems became apparent to our collective consciousness:

1. How do you know someone is really a person?
2. How do you know someone is who they say they are?

Initially, the “person” thing wasn’t a big issue, the internet was used for low-stake amicable activities, and impersonation, bots, and alternative accounts weren’t a big deal. As for the second issue, well, we used usernames and passwords.

But now we use the internet for everything, banking, work, brokerage.
