Take a quick peek at your to-do list. Chances are, changing or strengthening your password is not at the top of the list. While it’s understandable that we all have other priorities, the downside of weak or stolen passwords is the potential for damaging and costly data breaches.
To combat the threat of these breaches, security professionals are laser-focused on moving away from traditional passwords as a standard security protocol. In fact, a recent report from Portnox says that a full 92% of CISOs are implementing passwordless authentication as a way to secure their users. WAVE ID® Readers, which support FIDO2 protocol, can help you do just that.
Key takeaways
What is a FIDO2-Supported Card Reader?
A FIDO2 card reader is a device that enables passwordless authentication by reading credentials that are stored on a smart card, NFC security key, or other authenticator. Instead of typing a password, users authenticate by presenting a credential, like an ID badge or security key, to a compatible reader that is connected to a system.
FIDO2 authentication uses public-key cryptography to verify the user’s identity, making it resistant to phishing attacks or credential theft. Readers like the WAVE ID® allow users to simply tap their badge or credential to securely sign in without passwords.

How FIDO2 Card Readers Work
A FIDO2 card reader enables secure, passwordless authentication by allowing users to verify their identity with a physical credential instead of entering a password. These readers work with the FIDO2 authentication standard to provide fast, phishing-resistant login across devices, applications, and systems.
The authentication process relies on public-key cryptography and two core FIDO2 technologies: WebAuthn (Web Authentication) and CTAP (Client to Authenticator Protocol). Together, these standards allow devices, applications, and authenticators to communicate securely.
Step-by-Step Authentication Process
-
The user presents their credential
The user taps or presents a credential to the card reader connected to the workstation or device.
-
The reader communicates with the authenticator
The FIDO2 card reader detects the credential and communicates with the authenticator using CTAP. This securely passes authentication data between the reader and the system that is requesting verification.
-
The system verifies the user’s identity
Using WebAuthn, the operating system sends a cryptographic challenge to the authenticator. The credential signs this challenge with a private key stored securely on the device.
-
The login is approved
The signed challenge is verified using the corresponding public key stored by the service or system. If the signature matches, the user is authenticated and granted access without needing to enter a password.
Why Organizations Are Adopting FIDO2 Passwordless Authentication
It’s not surprising that many of the world’s leading tech companies, including Microsoft, Google, and Apple, support passwordless authentication via FIDO2 (Fast Identity Online) technology.
The FIDO alliance has made it its mission to rid the world of passwords by providing a seamless, secure, and interoperable passwordless authentication platform. FIDO2 works seamlessly across credential types, devices, platforms, and browsers.
As FIDO2 gains acceptance, enterprise and government users are combining this technology with their existing logical access solutions, utilizing proximity or contactless smart cards and readers. These types of intelligent Identity Access Management (IAM) solutions not only reduce the potential of a security breach, but they also save users time and effort by eliminating manual password entry.
FIDO2 Use Cases By Industry
Organizations across industries are adopting FIDO2 card readers to streamline authentication, strengthen security, and reduce the operational burden of password management. By allowing users to authenticate with a quick tap of a credential, FIDO2 readers make secure access faster and easier across a wide range of environments.
Healthcare Workstations and Clinical Environments
In the healthcare industry, speed and security are critical. Studies show that clinicians can save up to 45 minutes per shift per day by avoiding the repeated need to enter passwords when accessing workstations and electronic health records.
With FIDO2-enabled credential readers, clinicians can tap their badge or credential to authenticate instantly, allowing them to move quickly between workstations while maintaining strong security controls. This streamlined workflow gives healthcare professionals more time to focus on what matters most: hands-on patient care.
Enterprise and Corporate Workstations
For businesses, reducing time spent on password entry can significantly improve employee productivity. Traditional authentication methods often require workers to remember complex passwords, re-enter them throughout the day, or reset them when forgotten.
Passwordless authentication with FIDO2 card readers eliminates these friction points. Employees can securely sign in with a tap of their credentials, helping organizations improve efficiency while maintaining strong access controls.
Government and High-Security Environments
Government agencies and regulated industries often require strong authentication and strict identity verification standards. FIDO2 card readers support secure, phishing-resistant authentication while integrating with existing physical access credentials such as proximity cards or smart ID badges.
This approach enables organizations to strengthen Identity and Access Management (IAM) while maintaining compliance with security policies and regulatory frameworks.
Reducing IT Support and Password Management Costs
Password management creates a significant operational burden for IT teams. According to Gartner, 40% of help desk calls are password-related, and each manual password reset can cost organizations up to $70 per event.
By eliminating passwords and enabling secure credential-based authentication, FIDO2 card readers help reduce these support requests and lower IT overhead. Fewer password resets mean less downtime for employees and fewer administrative tasks for IT staff.
Benefits of FIDO2 Card Readers
Organizations adopting FIDO2 card readers gain significant advantages in both security and user experience. By replacing traditional passwords with secure credential-based authentication, FIDO2 technology helps reduce risk, improve productivity, and simplify identity management across enterprise environments.
Stronger Security and Phishing Resistance
Passwords remain one of the most common targets for cyberattacks. Phishing, credential theft, and password reuse can all lead to unauthorized access. FIDO2 card readers address these risks by replacing passwords with public-key cryptography, where authentication relies on a secure key pair.
Since the private key never leaves the user’s credential or device, attackers cannot intercept or reuse login information. This architecture makes FIDO2 authentication highly resistant to phishing and credential-based attacks.
Frictionless User Authentication
Entering complex passwords multiple times throughout the day slows users down and disrupts workflows. With a FIDO2 card reader, authentication becomes as simple as tapping a smart card, ID badge, or credential on the reader.
This streamlined login experience helps employees quickly access workstations and applications without sacrificing security. In fast-paced environments such as healthcare, manufacturing, or shared workstations, this speed can significantly improve operational efficiency.
Reduced Password Management Costs
Password management creates a significant burden for IT teams. Forgotten passwords, account lockouts, and manual resets generate a large number of help desk requests.
By eliminating passwords, FIDO2 card readers can dramatically reduce these support issues. Fewer password resets mean lower support costs, less downtime for employees, and fewer administrative tasks for IT staff.
Improved Compliance and Identity Assurance
Many industries including healthcare, finance, and government, must meet strict security and compliance requirements. FIDO2 authentication provides strong, phishing-resistant multi-factor authentication (MFA) that supports modern security frameworks such as Zero Trust.
When combined with smart cards or secure credentials, FIDO2 card readers help organizations verify user identity with greater confidence while meeting regulatory and internal security standards.
Seamless Integration with Existing Credentials
One of the key advantages of FIDO2 card readers is their ability to work alongside existing physical credentials, such as proximity cards, smart cards, and employee ID badges. Organizations can extend passwordless authentication without requiring users to carry additional devices.
This compatibility allows enterprises and government agencies to enhance their identity and access management (IAM) systems while preserving their current credential infrastructure.
