The most recent protocol from the FIDO Alliance, CTAP2 enables native platform support for user-friendly multi-factor authentication. It is integrated with W3C specifications to allow for direct support in upcoming browsers.

Additionally, Microsoft has further expanded platform compatibility by announcing support for FIDO2 in multiple Windows applications such as Windows Hello and Azure Active Directory. Here FIDO2 provides a secure, easy solution for a single user to log into shared Windows PCs.

Infineon’s FIDO2 development kit is based on the security-certified SLE 78 security microcontroller which supports USB and NFC interfaces on a single chip. This makes it ideal for both USB and USB/NFC token designs with the smallest possible form factors. In addition, the FIDO2 development kit hardware is equipped with a BLE controller for a convenient upgrade path towards triple interface designs supporting USB, NFC and BLE.

The SLE 78 security controller is Common Criteria EAL 6+ (high) certified and is equipped with Infineon Integrity Guard, which features robust digital mechanisms to protect secret data, highly sophisticated error detection capabilities and countermeasures against specific chip-level attacks. This development kit is therefore the ideal foundation for FIDO2 authenticators that demand the highest security levels.
