Frequently Asked Questions#

Which programming languages have dedicated passkey SDKs available?#

Passkey SDK coverage exists across C, Golang, Java, Node.js, PHP, Python, Ruby, Rust, Swift, C#/.NET and Kotlin. Corbado provides first-party SDKs specifically for Golang, Java, Node.js, PHP, Python, Swift (iOS) and Android (Kotlin), each offering session management and passkey-first authentication out of the box.

How does the Corbado Passkey Telemetry SDK help debug passkey login issues?#

The Corbado Passkey Telemetry SDK streams structured passkey events from the frontend and optionally the backend into pre-built analytics dashboards. It provides automatic error classification, funnel analysis and user-level process search, all using UUID-only identifiers to remain GDPR-compliant with zero impact on authentication performance.

What WebAuthn UX challenges does the Passkey UI Best Practice Library solve?#

The Passkey UI Best Practice Library is a framework-agnostic set of prebuilt components covering passkey sign-up, login and management flows. It handles WebAuthn UX edge cases including cross-device flows, fallback routing and platform-specific prompts, removing the need to design or maintain custom UI code.

How do I add passkeys to a PHP or Laravel application?#

Several PHP libraries support passkey implementation, including the WebAuthn Framework with a Symfony bundle, the Laragear WebAuthn package for Laravel and the asbiin laravel-webauthn package for two-factor and passwordless authentication. The Corbado PHP SDK offers a higher-level option with session management and passkey-first authentication built in.

What is the difference between a WebAuthn relying party library and a passkey SDK?#

A WebAuthn relying party library handles server-side protocol operations such as registration, attestation, authentication and assertion verification. A passkey SDK typically adds higher-level abstractions including session management, user management and prebuilt UI components, reducing the custom code needed to deliver a complete passkey login flow.
