Operating system and web browser support for FIDO2


The goal of this document is to highlight the operating system and browser ecosystems support for FIDO. The information provided is based on general availability (GA) product releases and YubiKeys that support the FIDO standards. The YubiKey 5 and Security Key Series support the FIDO2 standard that covers all the scenarios listed below. Previous generations of YubiKeys support the FIDO U2F standard. FIDO2 is backwards compatible with FIDO U2F but YubiKey + PIN scenarios are not supported on U2F only devices. Vendors are actively developing to improve support of YubiKeys and open standards. These tables will be updated as new information becomes available.

The tables focus on base functionality provided by browsers and platforms.  There can be slight differences in the implementations across systems. Vendors may choose to implement different user authentication experiences. Depending on the implementation, users may or may not need to enter in the user name as part of the authentication process. Additionally, these tables do not cover specific implementations by online services and applications. Review the Works With YubiKey Catalog for additional partner information or contact us if you have questions about specific implementations.

Applicable to all tables below, YubiKey + PIN scenarios (**) are not supported on U2F only devices.

*The current version of Firefox no longer supports FIDO on Android. Firefox is working to resolve the issue. Firefox version 79 is the latest version that supports Username with YubiKey and Username/Password + YubiKey scenarios.

  • FIDO PIN for user verification is not supported for external authenticators at this time.
  • Mobile apps that incorporate the Yubico Android SDK will be able to take advantage of additional capabilities with the YubiKey.  Each service provider will decide on which capabilities to implement.
