The major problem with OAuth as used by Blizzard is that it requires you to have a cell phone or tablet in order to use it. If you don't have one (and it appears to be required for the 'instant' authentication you appear to be pushing), it becomes much more cumbersome to use than a physical authenticator.
OAuth has nothing to do with the authentication, you can do OAuth with username and password, it's merely a framework for exchanging temporary tokens to KNOWN devices. The fact that I even need to explain this, shows your way out of depth and shouldn't be arguing this. It's used on every single mobile app you have that doesn't require login every time, most bank websites, and a lot of other companies. I guess you guys know more Microsoft, Okta, Apple, Google, and thousands of others who use this technology every day, apparently Sony is the leader in technology according to your standards.

This is why hardly participate on these forums, SE can do wrong to most posters here, no matter the facts stacked against them.
