The local unlock is accomplished by a user–friendly and secure action such as swiping a finger, entering a PIN, speaking into a microphone, inserting a second–factor device or pressing a button. The client’s private keys can be used only after they are unlocked locally on the device by the user. Authentication is done by the client device proving possession of the private key to the service by signing a challenge. It retains the private key and registers the public key with the online service. During registration with an online service, the user’s client device creates a new key pair. Start the testing and certification process here.The FIDO protocols use standard public key cryptography techniques to provide stronger authentication. These include FIDO Certified Universal Servers that support FIDO2 and all prior FIDO UAF and FIDO U2F devices for full backward compatibility with the full range of certified FIDO authenticators. ![]() As a best practice, the FIDO Alliance recommends online services and enterprises deploy a Universal Server to ensure support for all FIDO Certified authenticators.Ĭurrently, there are many FIDO2 Certified solutions available to support a wide variety of use cases. Additionally, the Alliance has introduced a new Universal Server certification for servers that interoperate with all FIDO authenticator types (FIDO UAF, WebAuthn, CTAP). FIDO2 Testing and CertificationįIDO Alliance provides interoperability testing and certification for servers, clients and authenticators adhering to FIDO2 specifications. Get a high-level overview of the steps to take for both of those changes here. WebAuthn is currently supported in Google Chrome, Mozilla Firefox, Microsoft Edge and Apple Safari web browsers, as well as Windows 10 and Android platforms.įor developers with existing web pages or applications that are looking to implement FIDO2, there are two changes that you will have to make to your application: 1) modifying the login and registration pages of your website or mobile application to use the FIDO protocols and 2) setup a FIDO server to authenticate any FIDO registration or authentication requests. It enables an external authenticator, such as a security key or a mobile phone, to work with browsers that support WebAuthn, and also to serve as an authenticator to desktop applications and web services.įind more information on FIDO2 here. The other component of FIDO2, Client to Authenticator Protocol (CTAP), is complementary to WebAuthn. FIDO2: Client to Authenticator Protocol (CTAP) Today, WebAuthn is part of the FIDO Alliance’s FIDO2 specifications and the FIDO Alliance runs certification programs to ensure compliance. ![]() WebAuthn was officially recognized as a W3C web standard in March 2019. ![]() They then worked within the W3C to finalize the API, which became known as Web Authentication, or WebAuthn. This standardization would grow the FIDO ecosystem by an entire community of web browsers and web application servers supporting the standard.įIDO Alliance member companies submitted the FIDO specifications to the W3C for formal standardization in 2015. ![]() The FIDO Alliance decided to partner with the World Wide Web Consortium (W3C), the international standards organization for the World Wide Web, to standardize FIDO Authentication for the entire web platform. The Alliance developed three technical specifications that defined a web-based API, enabling FIDO Authentication to be built directly into browsers and platforms. Understanding the relationship between FIDO Alliance and WebAuthnĪfter the release of its initial FIDO UAF and FIDO U2F specifications, the FIDO Alliance started a new journey to make FIDO Authentication more accessible to users worldwide. This security model eliminates the risks of phishing, all forms of password theft and replay attacks. Web services and apps can – and should – turn on this functionality to give their users an easier login experience via biometrics, mobile devices and/or FIDO security keys – and with much higher security over passwords alone.įIDO’s higher security comes from the use of cryptographic login credentials that are unique across every website, never leave the user’s device and are never stored on a server. FIDO2 enables users to leverage common devices to easily authenticate to online services in both mobile and desktop environments. Web Authentication (WebAuthn), a core component of FIDO Alliance’s FIDO2 set of specifications, is a web-based API that allows websites to update their login pages to add FIDO-based authentication on supported browsers and platforms.
