Introducing Passkeys in Scalekit

Scalekit now provides Passkeys as an authentication method that developers can enable directly within their apps. Passkeys replace passwords with secure, device-based authentication built on FIDO2 and WebAuthn standards. Users can sign in with a fingerprint, face scan, or device PIN, and your app gains a phishing-resistant login experience that’s faster, simpler, and safer.

Instead of relying on shared secrets, passkeys authenticate users through asymmetric cryptography. Each device creates a unique pair of keys — a private key stored securely on the user’s device and a public key stored on your server. When a user signs in, their device signs a one-time challenge with its private key. Scalekit verifies it using the public key, meaning no passwords are exchanged or stored. The result is authentication that’s secure by design and seamless to use.

A Security Standard That Has Already Arrived

The latest FIDO Passkey Index shows that 93% of all user accounts are already passkey-ready across platforms, and more than a third have a passkey enrolled. One in four sign-ins globally now uses passkeys, reflecting a rapid shift from experimental technology to mainstream adoption.

The data also shows that passkeys outperform older methods in every measurable way. They achieve a 93% login success rate compared to 63% for multi-factor or social logins, and they cut average sign-in time by 73% — from 31 seconds down to about 8 seconds. Companies that have deployed passkeys report an 81% reduction in sign-in–related support incidents, freeing developers and support teams to focus on building features rather than resetting credentials.

Taken together, these numbers show that passkeys are no longer a “nice to have.” They are a reliability and efficiency upgrade that improves both user experience and operational resilience.

Enabling Passkeys in Scalekit

If your app already uses Scalekit Auth, you can enable passkeys in minutes:

1. Open your Scalekit Dashboard
2. Go to Authentication → Auth Methods → Passkeys
3. Click Enable

Once enabled, users can register and manage their passkeys through Scalekit’s hosted page or via your own UI built using the Scalekit WebAuthn APIs. Passkeys work alongside existing authentication options such as SSO, magic links, and social logins, allowing you to roll out modern authentication without migrations or downtime.

Why This Matters Right Now

Passkeys directly address three of the biggest problems facing software teams today.

1. Security debt: Each stored password represents risk. Passkeys eliminate the need to store or hash secrets, removing entire categories of breach exposure.
‍
2. User experience: Every login that fails is a user lost. With higher success rates and near-instant sign-in, passkeys keep users moving through your app rather than your support queue.
‍
3. Operational cost: An 81%  drop in login-related help desk incidents means lower costs for resets and MFA troubleshooting, and more time for development.

In short, adopting passkeys is not just about security. It is about speed, retention, and credibility.

The Future of Authentication

With over 90% of the internet now passkey-ready, the transition away from passwords has already begun. What used to be a theoretical improvement is now an industry baseline.

Scalekit makes it simple to adopt this standard without rebuilding your identity stack. Our implementation brings cryptographic authentication to every developer, combining strong security with a user experience that feels native across platforms.

Authentication is changing, and fast. The apps that act now will define what secure and effortless login looks like in the years ahead.

FAQs

How do passkeys improve the security posture of B2B applications

Passkeys significantly improve security by replacing shared secrets with asymmetric cryptography based on FIDO2 standards. Since only a public key is stored on your server while the private key remains on the user device the risk of credential theft during a breach is virtually eliminated. This architectural shift removes the need for password hashing and mitigates phishing attacks as there are no secrets for users to reveal to attackers. By adopting this device based approach CISOs can effectively reduce security debt and protect enterprise data against modern identity threats without compromising user convenience or operational efficiency.

What technical standards govern the implementation of Scalekit passkeys

Scalekit passkeys are built upon the robust FIDO2 and WebAuthn global standards which facilitate secure and passwordless authentication across various platforms. These protocols ensure that authentication is phishing resistant and relies on device based biometric or PIN verification rather than memorized secrets. By leveraging these industry recognized standards developers can implement a secure login experience that is native to modern operating systems and browsers. This alignment with global security frameworks ensures that your application remains compliant with evolving regulatory requirements while providing a future proof identity solution for both internal teams and external customers.

How does switching to passkeys reduce operational support overhead

Transitioning to passkeys provides a substantial reduction in operational costs by minimizing common login issues. Industry data indicates that companies deploying passkeys report an 81 percent drop in sign in related support incidents such as password resets and multi factor authentication troubleshooting. With a 93 percent login success rate users experience fewer friction points which directly translates to fewer help desk tickets. This shift allows engineering and support teams to redirect their resources toward core product development and strategic initiatives rather than managing credential recovery workflows ultimately improving the overall efficiency and productivity of the organization.

Can passkeys be integrated alongside existing enterprise SSO solutions

Yes Scalekit allows passkeys to function seamlessly alongside existing authentication methods like Single Sign On magic links and social logins. This flexibility enables developers to roll out modern authentication gradually without requiring a full scale migration or causing system downtime. Users can choose their preferred method while the enterprise maintains high security standards. For B2B applications this means you can offer the convenience of passkeys to some users while still supporting legacy SSO requirements for others. This hybrid approach ensures a smooth transition to passwordless authentication while maintaining compatibility with diverse enterprise identity stacks and workflows.

Why are passkeys more efficient for end users during login

Passkeys optimize the user experience by reducing the average sign in time by approximately 73 percent. Instead of manually entering complex passwords or waiting for one time codes users can authenticate in about eight seconds using biometrics like fingerprints or face scans. This streamlined process achieves a much higher success rate compared to traditional multi factor or social logins. For engineering managers this means higher user retention and engagement as the friction typically associated with authentication is removed. By providing a faster and more intuitive entry point applications can deliver a premium experience that meets modern user expectations.

How does asymmetric cryptography prevent credential theft in passkeys

Passkey authentication utilizes asymmetric cryptography where a unique pair of keys is generated for each account. The private key stays securely on the user device while only the public key is stored on the Scalekit server. During authentication the device signs a unique challenge that the server verifies using the public key. This mechanism ensures that no shared secrets are ever transmitted or stored centrally. Even if a server is compromised the public keys are useless to attackers without the corresponding private keys providing a robust defense against large scale data breaches and credential stuffing attacks.

What is the process for enabling passkeys within Scalekit

Enabling passkeys in Scalekit is a straightforward process that takes only a few minutes. Developers simply need to log into the Scalekit Dashboard navigate to the Authentication section select Auth Methods then Passkeys and click Enable. Once activated passkeys can be managed through Scalekit hosted pages or custom user interfaces built with the Scalekit WebAuthn APIs. This ease of implementation allows teams to upgrade their security infrastructure without extensive code changes or complex backend reconfigurations. This rapid deployment capability is ideal for fast moving engineering teams looking to enhance their authentication stack with minimal effort.

What is the current level of global passkey readiness

Recent data from the FIDO Passkey Index shows that 93 percent of user accounts globally are already passkey ready across various platforms. Furthermore over one third of users have already enrolled a passkey and one in four global sign ins now utilize this technology. This rapid adoption signifies that passkeys have moved from experimental to a mainstream industry baseline. For CTOs and product leaders this represents a critical opportunity to adopt a widely supported standard that aligns with current user behavior and platform capabilities ensuring your application remains competitive and secure in the modern digital landscape.

How do passkeys help organizations address growing security debt

Every stored password represents a potential security liability or debt that organizations must manage through hashing and complex storage protocols. Passkeys eliminate this debt by removing the requirement to store or manage sensitive secrets entirely. By shifting to a cryptographic model organizations remove entire categories of breach exposure related to credential handling. This architectural simplification not only reduces the risk of massive data breaches but also lowers the long term maintenance costs associated with legacy security infrastructure. Addressing security debt with passkeys allows CISOs to build a more resilient and scalable identity foundation for their entire B2B application ecosystem.
