Framework

AuthenticationServices

Make it easy for users to log into apps and services.

Overview

Use the Authentication Services framework to improve the experience of users when they enter credentials to establish their identity.

  • Give users the ability to sign into your services with their Apple ID.

  • Enable users to look up their stored passwords from within the sign-in flow of an app.

  • Share data between an app and a web browser using technologies like OAuth to leverage existing web-based logins in the app.

  • Create a single sign-on (SSO) experience in an enterprise app.

Simple and straightforward sign-up and sign-in flows reduce the burden on the user to remember passwords. This encourages the use of strong passwords, which improves security.
