FIDO - Fast Identity Online

Fast Identity Online (FIDO) Standards are the authentication protocols that bridge security and enhance user experience. The FIDO Alliance has developed an open industry association, aka FIDO Standards offering better security than passwords or one-time passwords (OTP). Authentication with FIDO Standards ensures fast, secure, and strong user authentication.

Four FIDO Specifications

FIDO Authentication digitally defines user authentication and reduces password reliance and redundancy created via complex passwords. The FIDO UAF, U2F, aka CTAP1, and FIDO2, are the specifications published by the FIDO Alliance for defined scalability.

Universal Authentication Framework (UAF)

The Universal Authentication Framework intends to facilitate complete biometric authentication without passwords. According to the UAF, user authentication is required while initially accessing an application. The FIDO UAF Challenges allow the user access through a private key to get verified with biometrics on the device.
The UAF specifies guiding users with the creation and management of policies for transaction verification. The FIDO Standard focuses on improvising security and providing users and teams with a satisfactory experience.

Universal Second Factor (U2F)

U2F standard implies guiding users on strengthening and simplifying 2FA (two-factor authentication) using near-field communication or devices which have technology similar to smart cards. The smart card or USB device communicates with the host system using the HID protocol and allows the browser to access the security features of the device. Once communication is established, there is challenge authentication for the user, where a unique device key is generated. Browsers support U2F specification and utilize the generated key as 2FA for online services and transactions.


Client to Authenticator Protocol empowers cryptographic authentication as a mobile phone to ensure system compatibility with a laptop or other device. The protocol of CTAP was based on U2F released by FIDO Alliance, where CTAP has two protocols, CTAP1 and CTAP2.


FIDO2, an expanded version of CTAP, enables no password authentication and is built on the U2F Protocol. The standard provides passwordless authentication concerning the web API – WebAuthn. FIDO2 enables browsers and OS to communicate with external authenticators, such as mobile phones, to create passwordless authentication.

Six FIDO Authentication Benefits

OmniDefend allows users to login securely with FIDO2 authentication after OmniDefend authentication policies are configured in the portal. If the user attempts to log in using OmniDefend SSO over Android or iOS, then the user will be prompted to authenticate using the biometric options available.
