To easily access cryptographic tokens. Tokens are physical devices built in to the system, located on attached hardware (like a smart card), or accessible through a network connection. Tokens store cryptographic objects like keys and certificates. They also may perform operations

Using Single sign-on and Apple services such as

• Apple ID, Managed Apple ID,

• iCloud, iMessage, and FaceTime let users communicate securely,

• create documents online, and back up personal data—all without compromising an organization’s data.

• Each service uses its own security architecture, which ensures the following: secure handling of data (whether it’s on an Apple device or in transit over a wireless network), protection of users’ personal information,

• and threat protection against malicious or unauthorized access to information and services. MDM solutions can be used to restrict and manage access to specific services on Apple devices.

Authentication is retrieving a credential from an authority after providing an assertion that proves your identity.

PassKit (Apple Pay and Wallet- (level three service)

Process Apple Pay payments in your app, and create and distribute passes for the Wallet app.

The Wallet app allows users to organize their boarding passes, tickets, gift cards, and loyalty cards. It also lets users manage their payment cards for Apple Pay. Using the PassKit framework, you can add passes to Wallet and have these passes appear on the user’s lock screen based on the time and place when the pass is relevant. You can also update a pass’s content using push notifications.

Use Apple CryptoKit to perform common cryptographic operations:

• Compute and compare cryptographically secure digests.

• Use public-key cryptography to create and evaluate digital signatures, and to perform key exchange. In addition to working with keys stored in memory, you can also use private keys stored in and managed by the Secure Enclave.

• Generate symmetric keys, and use them in operations like message authentication and encryption.

Prefer CryptoKit over lower-level interfaces. CryptoKit frees your app from managing raw pointers, and automatically handles tasks that make your app more secure, like overwriting sensitive data during memory deallocation.

You easily access cryptographic tokens. Tokens are physical devices built in to the system, located on attached hardware (like a smart card), or accessible through a network connection. Tokens store cryptographic objects like keys and certificates. They also may perform operations—for example, encryption or digital signature verification—using these objects. You use the framework to work with a token’s assets as if they were part of your system, even though they remain secured by the token.

You can also use the framework to enable a token for two-factor authentication in macOS. Authentication services manage associations between users and identities stored on a token, granting users access when the appropriate token is present and unlocked. You supply a token driver in the form of an app extension that bridges the gap between authentication services and the underlying token hardware.
