Hideez Key 3 supports FIDO2 and FIDO U2F protocols for passwordless logins within the FIDO ecosystem. It is suitable for both personal and enterprise use within the Hideez Authentication Service, a cloud-based passwordless Identity and Access Management (IAM) solution. Hideez Key 3 operates on the 125 kHz frequency bandwidth for RFID functionality and uses Bluetooth 4.0 for connectivity.
