AppleConnect is the Apple-specific single sign-on (SSO) and authentication system that allows a user to access certain applications inside Apple's network. This secure access is facilitated through Apple's Directory Services database. On iOS, apps featuring AppleConnect have the option of a gesture-based login system. The user sets up a pattern and needs to input that same pattern in, instead of a password or a numeric code. Apple deployed this login system internally for use in employee-only applications (i.e. Concierge, Switchboard) for iOS devices.
