With single device - you're right... but this becomes really a problem when you expect your customers to use multiple devices: computers at home, at work, smartphone, iPad...
how would you suggest your customer which login to use the first time she tries to sign in on another device?
From user perspective having several sign-in options is a source of confusion: first day I sign in with Facebook... next day I come in and don't remember which service I've used to sign in with? And this time I try Twitter only to see none of my data.
How do you guys solve that problem? I think, this might be even the bigger problem than having 20% or 30% "drop out" on sign up process.
yup, some sort of example how it would work for me as a developer would be awesome!
E.g. I have uservoice, optimizely, ganalytics, kissinsights and totango snippets in my app right now - what UberJS would do for me? Would my biz. partner be able to add new snippets/delete old ones on his own (without interrupting my flow ;)?
My personal problem with this is that in Estonia MobileID (fancy way to authenticate yourself and authorize transactions in banks, public services and other web services - advertised as a more secure way comparing to username/passwords and one time tokens) works through Sim Toolkit.
