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 deb: 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.
