regarding point 3, I feel like familiarity bias is such a difficult thing to overcome sometimes with UX. However poor the experience of the standard signup/auth process is, users have already learned the complexity, and the risk is super high when you're showing people a totally new type of hurdle they have to jump to access your product. Even if it's less complex objectively, if they fail the first time there's a high chance that user is never coming back. But I think authentication in general is a problem which really needs to be solved, and in a standards-based way. For instance, with connecting to public wifi networks (i.e. at an airport), it's absurd to have to go through a web page every time to log in. Also with the proliferation of IoT devices, it's always painful to go through the process of connecting it to my bluetooth and/or wifi. There should be some kind way to handle trust systematically through my smartphone without having to manually type a bunch of passwords.
