Open standard for user authentication
- FIDO2 (Fast IDentity Online 2) is an open standard for user authentication that aims to strengthen the way people sign in to online services to increase overall trust. FIDO2 strengthens security and protects individuals and organizations from cybercrimes by using phishing-resistant cryptographic credentials to validate user identities.

What is FIDO2 (Fast IDentity Online 2)?
With FIDO Authentication, users sign in with phishing resistant credentials, called passkeys. Passkeys can be synced across devices or bound to a platform or security key and enable password-only logins to be replaced with secure and fast login experiences across websites and apps.
FIDO2 has two main components: WebAuthn and CTAP (Client to Authenticator Protocol). Collectively, WebAuthn and CTAP deliver a cryptographically secure, convenient and interoperable login experience. In short, the main differences between FIDO 1.0 and FIDO2 are standardization, scope, interoperability and adoption.

Also spelled as “FIDO 2,” FIDO2 is an overarching term for the FIDO Alliance specifications. These are the World Wide Web Consortium’s (W3C) Web Authentication (WebAuthn) specification and FIDO Alliance’s Client-to-Authenticator Protocol (CTAP). FIDO2 provides a passwordless way to authenticate users and addresses security, convenience, privacy, an...
FIDO2 does not store credentials on a server and uses unique cryptographic login credentials, which helps reduce the likelihood of phishing, password theft, and replay attacks. Cybercrime has dramatically risen; 880,418 complaints were filed in 2023, a 10% increase over the previous year. Reported losses were over $12.5 billion. FIDO2 authenticatio...
FIDO2 can be cost-prohibitive —in terms of time and money—and it is also cumbersome to integrate into legacy production environments, remote workforces, and account recovery solutions. Additionally, FIDO2 does not safeguard against timing vulnerability attacks (an attack that links stored user accounts in vulnerable authenticators). Since FIDO2 rel...
FIDO2 passwordless authentication uses public-key cryptography for security and convenience. Both a private and public key are used to validate who the user is. To take advantage of FIDO2, a user needs to sign up at a FIDO2-supported site to choose a security key, such as FIDO2 Webauthn or a platform module. The site generates a FIDO2 authenticatio...
The original FIDO was created to foster stronger authentication standards for passwords and logins. The first passwordless protocol, called FIDO Universal Authentication Framework (FIDO UAF), and the second, FIDO Universal Second Factor (FIDO U2F), were released at the same time in 2014. FIDO UAF and FIDO U2F are the two protocols, but they are dif...
Each organization and industry has their own requirements as it relates to identity authorization and authentication. If FIDO2 is right for your organization, you might want to explore solutions, such as StrongDM’s privilege credential management, which can help you eliminate security gaps by never exposing credentials to the end-user.
FIDO2 has become a standard adopted by major device manufacturers and web platforms alike with ease of use, privacy, and security as its main advantages. It allows for passwordless authentication without cryptography keys being stored on a server, making it much more difficult to compromise credentials. The FIDO Alliance has been working on standar...
History of FIDO2
The FIDO (Fast IDentity Online) Alliance was founded in 2012 by PayPal, Lenovo, Nok Nok Labs, Validity Sensors, Infineon, and Agnito to find a way to create a passwordless authentication protocol. Google, Yubico, and NXP joined the alliance in 2013. In 2014, PayPal and Samsung collaborated to launch the first FIDO authentication protocol for the Samsung Galaxy S5, allowing users to log in and shop with a finger swipe and pay with PayPal. In December 2014, the first full FIDO passwordless prot...
How to Assess Whether You Need a FIDO2 Certification
The FIDO Alliance has a FIDO certification program that verifies how compliant and secure different services and applications are. There are various levels of certifications to determine how interoperable organizations and their products are with FIDO specifications. There is a specific certification for FIDO2, and a FIDO2 Certified Server can accept any FIDO2 Certified authenticator, even if they’re made by different companies. FIDO certifications include: · Functional Certification, a compr...
FIDO Certifications for Professionals
In addition to product certifications, the FIDO Alliance also has a FIDO Certified Professional program. It evaluates how well a candidate can deploy FIDO authentication solutions, analyze business requirements, design and implement technical requirements, validate business and technical requirements for implementation, and educate others about authentication. This certification is not specific to FIDO2 but assesses someone’s overarching knowledge of FIDO standards. Technology architects, sec...
