Pi Sign-in allows supported third-party websites and apps to offer Pi accounts as a sign-in or sign-up option. It helps provide the infrastructure that allows applications and services to recognize, connect, and serve users across and outside the ecosystem. This means Pioneers can access supported services with their Pi account instead of creating a new account or password for every app. Why would third-party services or websites want to integrate Pi Sign-in? Pi Sign-in creates a simpler way to connect them with Pi’s large user base and bring Pi users into their own product experiences. It also gives Pi more presence in third-party contexts while offering a way to tap into the additional benefits and resources of Pi Network, besides user traffic.
