YoAuth (opens in new tab)

https://yoauth.herokuapp.com/authorize?redirect_to=http://yo... and here too

The 2 hour product was doomed, but I've rewritten it enough to be secure.

To be fair, we don't know what goes on behind the scenes. Yo has simply proven that its creators are audacious enough, and good enough at marketing, to make something go viral. Perhaps they have other ideas, other business plans that are currently in stealth, and they're getting funding for them under the Yo umbrella. These are smart people investing in them, and Occam's Razor would seem to indicate that it's highly unlikely that the investors all got collective amnesia from head injuries and changed their vetting/due diligence strategies overnight.

Don't get me wrong, the app is fairly ridiculous. Projects like this though help show what even the simplest of concepts can provide, though.

To be fair, I'm not sure how secure YoAuth would be, but this particular hack seems like an awesome use of it. It's simple to use and could compete alongside something like Google Authenticator as a simple way to log in to something.

I just a headline today that the company behind yo released a new photo messaging app: http://thenextweb.com/apps/2014/07/28/makers-yo-back-new-mes...

Much easier to berate than create.

Same here. I'm having a hard time understanding why I should use this. What's the benefit?

You need to use your Yo username.

The security is way beyond questionable.

Seriously, don't use this. (Alice tries to log in to Bob's account. Bob receives a yo. Bob yos back to be nice without knowing this is an oauth scheme. Alice now has access to Bob's account.)

But that's not to critique these guys, because I think this is a fantastic hackathon project!

As soon as AUTHYO yo-s you, it's popped to the top of your Yo friend list. So it's very quick to yo back.

A friend and I built a similar service (also at the Yo hackathon) and what you mention is similar to the way we handled it. I don't think it's been publicly announced, but Yo can now receive links on iOS.

The service we built (http://yosesame.com) works by having you Yo YOSESAME, which signs you up if you aren't already and responds with a URL that logs you in right way. The way Yoauth approached it is interesting, but you're right it's a bit strange to have to receive a Yo.

I would recommend http://yofor.me/ for that

It lets you log into websites using Yo.

Actually you don't even need that, *.herokuapp.com comes with https for free.

Whats the difference from oAuth?
