The problem with letting Twitter authenticate as you is anyone who breaks into your Twitter account can authenticate as you on any website that accepts Twitter authentication.
The problem with Persona is exactly the same.
The problem is that the article that provoked this question is kinda [...] mostly saying "Woe! All methods of assuring the computer you are who you say you are can be faked in some way! Dooooom!" and kinda heads off towards the idea that before you can log onto your computer you'll need to juggle balls in front of the webcam[1] and then give it a skin-sample[2].
Actually, retina scanning or thumbprint recognition would be ideal. Any other way can be tampered with, stolen, faked, duped or...so I'm entirely sympathetic to Wired's tone. Passwords are a relic of the good ol' DOS days. Command line shit. What people did waaaaaaaaaaaaaay back in the day when the only way to tell a website or computer you were you was through a special seekret text string of some sort. Text. String. We've moved way beyond computers that can handle text alone and way beyond computers that only have 16KB onboard memory to handle the text, yet we're still signing in to websites the same way we did back in the 90s. Big problem.
