I don't know if this is the correct tactical implementation, relies upon having a cloud-based account that never goes away or gets disrupted in any fashion etc etc etc etc. However! If you have built any product which has gotten traction, you know just how much of a pain auth still is in 2023. It will always be your number one customer service pain point -- either unable to remember the email address your users signed up with so they can't initiate a reset password flow, or not getting an OOB email to start said flow, and so on. Auth in its current state is a complete drain on company time, resources, and money. Extrapolating out, I really wonder what a raw cost of the world's total GDP is taken up by dealing with auth issues. Any kind of breakthrough here would be such a net benefit to the human race as a whole. Even the half step of OAuth, even with all of its complexity and "did I use Google or Facebook or Apple to sign into this site?", even that reduced friction enough to be such a material benefit to customer service. If we can make signing into a service as easy as unlocking your phone, there would be a huge productivity jump.
