Specification development is a core element of FIDO Alliance’s mission to reduce the world’s reliance on passwords. Through its technical working groups, the FIDO Alliance publishes specifications in two areas: user authentication and secure device onboarding. FIDO Alliance also submits mature technical specification(s) to recognized standards development organization(s) for formal standardization.
User Authentication Specifications
The FIDO Alliance has published three sets of specifications for simpler, stronger user authentication: FIDO Universal Second Factor (FIDO U2F), FIDO Universal Authentication Framework (FIDO UAF) and the Client to Authenticator Protocols (CTAP). CTAP is complementary to the W3C’s Web Authentication (WebAuthn) specification; together, they are known as FIDO2.
FIDO standards use standard public key cryptography techniques to provide phishing-resistant authentication with cryptographic key pairs called passkeys. FIDO is designed from the ground up to protect user privacy and prevent phishing. Every passkey is unique and bound to the online service domain. The protocols do not provide information that can be used by different online services to collaborate and track a user across the services. Biometric information, if used, never leaves the user’s device.

Device Onboarding Specifications
The FIDO Alliance’s FIDO Device Onboard specification is an automatic onboarding protocol for edge nodes and IoT devices devices. The FDO protocol is a freely available standard that champions a ‘zero trust’ approach to enable devices to quickly and securely onboard to cloud and edge management platforms.
Device onboarding is the process of installing secrets and configuration data into a device so that the device is able to connect and interact securely to cloud and edge management platforms. The platform is used by the device owner to manage the device by: patching security vulnerabilities; installing or updating software; retrieving sensor data; interacting with actuators; etc. FDO is an automatic onboarding mechanism, meaning that it is invoked autonomously and performs only limited, specific, interactions with its environment to complete. FDO permits late binding of device credentials, so that one manufactured device may be onboarded, without modification, to many different platforms.
