Security Keys

FIDO Security Keys

Supports a wide range of Security Keys, such as the YubiKeys 4 and 5 series as well as Nitrokeys. Security Keys can be directly connected over USB-C and NFC. USB-A keys require an additional USB OTG cable.

NFC Sweetspot

Each smartphone has a different sweetspot where the NFC connection works best. Our Hardware Security SDK shows this spot to make it easy for the user to place their NFC Security Key.

The original sweetspot data was collected by McLear Ltd.
