The OpenID Foundation, the organization behind the OpenID open standard and decentralized authentication protocol, has penned an open letter to Apple in regards to the company’s recently announced “Sign In with Apple” feature.
In its letter, the organization said that Apple has built Sign In with Apple on top of the OpenID Connect platform, but the Cupertino company’s implementation is not fully compliant with the OpenID standard, and as a result “exposes users to greater security and privacy risks.”
