The new element of Fabric is Digits, an authentication service which relies on your mobile phone number as the key source of ID. Want to sign up for a new app? Rather than having to create a new identity or rely on an existing third party, Digits lets you connect the service to your mobile number. We’re familiar with the idea of using our mobile phones for two-factor authentication; this takes that a step further.
With so many unified sign in options: Facebook, Twitter, Google etc will we want a further option? Only time will tell.
@bryceroney Not when I have two US numbers, an Australian mobile number, a NZ number, an Australian landline number…

Update: As Christopher Neugebauer points out, many people also have multiple phone numbers – another potential stumbling point.
