FIDO2 passkeys are cryptographic key pairs typically stored on a device that authenticate the user for various applications and services. A public key is stored on the application server, and a private key is stored on an end user’s device. When a user tries to log in to an application, FIDO passkeys leverage Bluetooth® across your organization by using FIDO authenticators to authenticate endpoint devices, simultaneously securing and streamlining your IAM strategy.

Benefits of Secure Passwordless Access

Increase Productivity

Passkeys cut login time, reduce password resets, and lower help desk calls—using biometric sign-ins your users already know and trust.

FIDO2 passkey authentication uses Bluetooth to communicate between an end user’s registered device (FIDO authenticator) and the device upon which the user is logging into the application. The application issues a security challenge to the user’s registered device via Bluetooth. The user is then prompted to authenticate themselves into your organization’s system using biometrics to accept the sign-in request challenge, which is signed with the private key on the user’s registered device and sent back to the application to be verified with the corresponding public key, after which the user is signed in, if successful.

With FIDO2 passkeys (which are based on FIDO authentication), proximity to the device upon which the application or service is being accessed is always necessary. This helps reduce risk against the most common attacks and enables a familiar user experience that is consistent across all platforms and devices.

Enterprise passkeys bring real security gains to high-stakes environments without adding complexity for users or IT. Here’s how organizations are putting them to work:

  • Enterprise: Organization-wide passkey authentication reduces phishing risk and helps desk volume by replacing passwords across cloud and on-prem apps while keeping access simple for remote teams.
  • Healthcare: Protect patient data and streamline clinical logins with passwordless access that aligns with HIPAA requirements.
  • Government: Meet FIPS and NIST mandates with phishing-resistant passkey authentication for employees and contractors across hybrid environments. •
  • Finance: Safeguard high-value systems and customer data with strong, credential-free passkey solutions that lower fraud risk.

What are passkeys in identity and access management?

Passkeys are phishing-resistant credentials that replace passwords. They’re tied to your device and identity, and are used to authenticate with a simple biometric or device unlock—no memorization, no reuse.

How do passkeys improve security compared to passwords?

Passkey authentication eliminates common attack vectors such as password reuse, brute-force guessing, and theft. They use public key cryptography to ensure credentials can’t be intercepted or replayed.

Can passkeys resist phishing attacks?

Passkeys are bound to a legitimate service and can’t be tricked into connecting with fake websites or apps, making phishing attempts ineffective.

Where are passkeys stored?

FIDO2 Passkeys are securely stored on the user’s device or in a cloud keychain protected by the operating system. Private keys never leave the device.

Are passkeys supported across devices and platforms?

Passkeys work across major platforms like iOS, Android, Windows, and macOS, with syncing support through Apple, Google, and Microsoft ecosystems.
