Summary – Faced with password breaches, phishing, credential stuffing and rising support costs that sap productivity, switching to passwordless authentication is essential. Passkeys rely on FIDO2 standards, store the private key in a Secure Enclave/TPM, authenticate via biometrics or PIN, integrate with all OSes and support encrypted sync or open-source management to avoid vendor lock-in, while providing OTP and recovery codes. Solution: plan a phased rollout, formalize creation, sync and revocation workflows, and integrate passkeys into your IAM to cut support tickets by up to 90%, bolster security posture and optimize IT costs.
In a context where cyberattacks massively target credentials and passwords have become an operational burden, Passkeys are emerging as a pragmatic solution. By leveraging asymmetric cryptography, they eliminate vulnerabilities related to phishing and password reuse while delivering a smooth user experience through biometrics or a simple PIN. With the adoption of cloud services and business applications skyrocketing, migrating to a passwordless authentication model enables organizations to achieve enhanced security, simplicity, and IT cost control.
The Limitations of Passwords and the Urgency for a New Standard
Passwords have become a breaking point, amplifying the risk of compromise and support costs. Organizations can no longer afford to make them the cornerstone of their security.
Vulnerabilities and Compromise Risks
Passwords rely on human responsibility: creating robust combinations, renewing them regularly, and storing them securely. Yet most users prioritize convenience, opting for predictable sequences or reusing the same credentials across multiple platforms.
This practice opens the door to credential-stuffing attacks or targeted phishing campaigns. Data stolen from one site is often tested on others, compromising internal networks and critical portals.
Beyond account theft, these vulnerabilities can lead to leaks of sensitive data, reputational damage, and regulatory penalties. Remediation costs, both technical and legal, often exceed those invested in preventing these incidents and highlight the importance of optimizing operational costs.
Costs and Complexity of Password Management
IT teams devote a significant share of their budget to handling reset tickets, sometimes up to 30% of total support volume. Each request consumes human resources and disrupts productivity.
At the same time, implementing complexity policies—minimum length, special characters, renewal intervals—creates friction with users and often leads to unauthorized workarounds (sticky notes, unencrypted files).
Example: A Swiss insurance organization experienced an average of 200 reset tickets per month, representing a direct cost of around CHF 50,000 per year in support time. This situation clearly demonstrated the pressure on IT resources and the urgent need to reduce these tickets and launch a digital transformation.
User Friction and Degraded Experience
In professional environments, strong passwords can become a barrier to digital tool adoption. Users fear losing access to their accounts or are reluctant to follow renewal rules.
Result: attempts to memorize passwords through risky means, reliance on unapproved third-party software, or even outright abandonment of applications deemed too cumbersome.
These frictions slow down new employee onboarding and create a vicious cycle where security is compromised to preserve user experience.
How Passkeys and FIDO2 Authentication Work
Passkeys rely on an asymmetric key pair, ensuring no sensitive data is stored on the service side. They leverage the FIDO2 standards, already widely supported by major ecosystems.
Asymmetric Authentication Principle
When creating a Passkey, the client generates a key pair: a public key that is transmitted to the service, and a private key that remains confined in the device’s hardware (Secure Enclave on Apple, TPM on Windows).
At each authentication attempt, the service sends a cryptographic challenge that the client signs locally with the private key. The signature is verified using the public key. At no point is a password or shared secret exchanged.
This mechanism eliminates classic attack vectors such as phishing, replay attacks, or password interception, because the private key never leaves the device and cannot be duplicated.
Storage and Protection of Private Keys
Modern environments integrate secure modules (Secure Enclave, TPM, TrustZone) that isolate the private key from the rest of the operating system. Malicious processes cannot read or modify it.
Biometrics (fingerprint, facial recognition) or a local PIN unlocks access to the private key for each login. Thus, even if a device is stolen, exploiting the key is nearly impossible without biometric authentication or PIN.
This isolation strengthens resilience against malware and reduces the exposure surface of authentication secrets.
FIDO2 Standards and Interoperability
The FIDO Alliance has defined WebAuthn and CTAP (Client to Authenticator Protocol) to standardize the use of Passkeys across browsers and applications. These standards ensure compatibility between devices, regardless of OS or manufacturer.
Apple, Google, and Microsoft have integrated these protocols into their browsers and SDKs, making adoption easier for cloud services, customer portals, and internal applications.
Example: A mid-sized e-commerce portal deployed FIDO2 Passkeys for its professional clients. This adoption demonstrated that the same credential works on smartphone, tablet, and desktop without any specific plugin installation.

Operational Challenges and Best Practices for Deploying Passkeys
Implementing Passkeys requires preparing user flows, managing cross-device synchronization, and robust fallback strategies. A phased approach ensures buy-in and compliance.
Cross-Device Synchronization and Recovery
To provide a seamless experience, Passkeys can be encrypted and synchronized via cloud services (iCloud Keychain, Android Backup). Each newly authenticated device then retrieves the same credential.
For organizations reluctant to use Big Tech ecosystems, it is possible to rely on open source secret managers (KeePassXC with a FIDO extension) or self-hosted appliances based on WebAuthn.
The deployment strategy must clearly document workflows for creation, synchronization, and revocation to ensure service continuity.
Relying on Managers and Avoiding Vendor Lock-In
Integrating a cross-platform open source manager allows centralizing Passkeys without exclusive reliance on proprietary clouds. This ensures portability and control of authentication data.
Open source solutions often provide connectors for Single Sign-On (SSO) and Identity and Access Management (IAM), facilitating integration with enterprise directories and Zero Trust policies.
A clear governance framework defines who can provision, synchronize, or revoke a Passkey, thus limiting drift risks and ensuring access traceability.
Fallback Mechanisms and Zero Trust Practices
It is essential to plan fallback mechanisms in case of device loss or theft: recovery codes, temporary one-time passcode authentication, or dedicated support.
A Zero Trust approach mandates verifying the device, context, and behavior, even after a Passkey authentication. Adaptive policies may require multi-factor authentication for sensitive operations.
These safeguards ensure that passwordless doesn’t become a vulnerability while offering a smooth everyday experience.
Example: An industrial manufacturing company implemented a fallback workflow based on dynamic QR codes generated by an internal appliance, demonstrating that a passwordless solution can avoid public clouds while remaining robust.
Benefits of Passkeys for Businesses
Adopting Passkeys dramatically reduces credential-related incidents, cuts support costs, and enhances user satisfaction. These gains translate into better operational performance and a quick ROI.
Reducing Support Tickets and Optimizing Resources
By removing passwords, password-reset tickets typically drop by 80% to 90%. IT teams can then focus on higher-value projects.
Fewer tickets also mean lower external support costs, especially when SLA-driven support providers are involved.
Example: A Swiss public service recorded an 85% decrease in lost-password requests after enabling Passkeys, freeing the equivalent of two full-time employees for strategic tasks.
Improving Productivity and User Experience
Passkeys unlock in seconds, without lengthy typing or risk of typos. Users more readily adopt business applications and portals.
Reduced friction leads to faster onboarding and less resistance to change when introducing new tools. For best practices, review our user experience guidelines.
This smoothness promotes greater adherence to security best practices since users no longer seek workarounds.
Strengthening Security Posture and Compliance
By removing server-side secret storage, Passkeys minimize the impact of user database breaches. Security audits are simplified, as there are no passwords to protect or rotate.
Alignment with FIDO2 and GDPR and Zero Trust principles strengthens compliance with standards (ISO 27001, NIST) and facilitates auditor justification. Asymmetric cryptography paired with secure hardware modules now constitutes the industry standard for identity management.
Adopt Passwordless to Secure Your Identities
Passkeys represent a major shift toward authentication that combines security, simplicity, and cost control. By relying on open standards (FIDO2), they eliminate password-related vulnerabilities and deliver a modern, sustainable user experience.
A gradual implementation that includes secure synchronization, fallback mechanisms, and Zero Trust governance ensures successful adoption and fast ROI.
