When it comes to security, we often think primarily of protecting our data: encrypting it to make sure that nobody else can access it. But just as important as that is the concept of authentication: proving that we are who we say we are.
Apple has made great strides with authentication in the past few years. Biometric measures like Touch ID and Face ID help make it easier for users to identify themselves and ensure that only they can access their private data.
In Apple’s usage, that authentication has generally been inward-facing: users control access to their own files and data, and the system checks to see whether or not we are the person who should be allowed in. But beginning in iOS 13, a few minor updates will start moving that authentication into the public realm, opening up the ability for us to prove our identity to others. And there’s a lot more room for Apple to expand there.
