The secure element allows for storing, retrieving, and sending information securely. In this post, we’ll review what a smart card is, the capabilities and advantages of using a YubiKey as a smart card, and how the YubiKey interacts with the Yubico Authenticator app on iOS to support use cases like certificate-based authentication for clients, signing email, or decrypting messages and documents on any iOS device.Ī generic smart card is just a physical device that comes in various sizes and shapes (from a key to a card) and has a computer chip with an embedded secure element. Smart cards meet this requirement, including the YubiKey 5 FIPS Series which enables government agencies and regulated industries to meet the highest authenticator assurance level 3 (AA元) requirements. Recently, the Office of Management and Budget (OMB) also released a memo requiring federal agencies to meet security requirements to adopt phishing-resistant MFA. The YubiKey 5 Series key is ideal as a smart card on iOS because it provides hardware-backed security and portable credentials, supports the PIV standard, and can communicate with any Apple device physically over the Lightning connector or wirelessly over NFC. With the portability and multi-protocol support offered by Yubico’s security keys, it’s now possible to use any personal identity verification (PIV)-enabled YubiKey on any supported iOS device as a certificate-based smart card.Īs of iOS 14.2, Apple provides native support for smart cards, enabling any PIV-compatible smart card to interact with an iPhone without any additional hardware readers or software. Today, smart cards come in many form factors, from a credit card size that fits in your wallet to a hardware security key that fits on your keychain. There’s only one problem… the typical credit card-shaped smart card didn’t work well, if at all, on mobile devices without additional hardware and software. Certificate-based smart cards have been one of the most trusted and proven implementations of multi-factor authentication for over 20 years.
