Laravel Webauthn Laravel Package

Product Decisions This Supports

• Passkey / passwordless roadmap: This package is the Laravel-native integration layer for WebAuthn (FIDO2) ceremonies, so it directly underpins decisions like "do we ship passkeys at sign-in this half?" versus "stay password + TOTP for now."
• Build vs. buy on authentication: Rolling your own WebAuthn attestation/assertion verification, CBOR parsing, and credential storage is weeks of specialist work with a high blast radius if wrong. Adopting this package is the "buy" answer for the protocol layer, leaving product differentiation in enrollment UX, recovery flows, and step-up policy.
• Security & compliance posture: Supports decisions around phishing-resistant MFA for admin/privileged accounts, PSD2-style strong customer authentication, and enterprise procurement questionnaires that now ask "do you support passkeys?"
• Conversion and support-cost modeling: Fewer password resets and faster repeat sign-in are measurable product outcomes; this package makes the experiment cheap enough to A/B.
• Release 6.0.0 specifically: The library moves to webauthn-lib 5.3 and returns CredentialRecord instead of the now-deprecated PublicKeyCredentialSource. For a PM this is a dependency-health signal (upstream is actively maintained, deprecated APIs are being retired) plus a scheduled engineering cost if you've customized credential storage. It does not change end-user behavior — no new product capability, no UX change — so it should be planned as maintenance, not sold as a feature.

When to Consider This Package

Consider adopting when:

• You're on a supported Laravel version and want passkeys/security keys without owning the WebAuthn protocol implementation.
• Your use case is standard registration + authentication ceremonies (platform authenticators like Touch ID/Windows Hello, or roaming FIDO2 keys).
• You need multiple credentials per user, credential naming/management, and a path to step-up authentication for sensitive actions.
• You can accept the package's storage model or afford the integration work to plug in your own credential repository — this is precisely the surface that 6.0.0 breaks, so scope that early.
• You want the option to add passkeys as a secondary factor first, then promote to primary sign-in later.

Look elsewhere or defer when:

• You need fully managed/hosted passkey infrastructure with SLAs (a vendor like a dedicated auth provider is a better fit than a self-hosted OSS package).
• Your stack isn't Laravel, or you're several major versions behind — the version coupling here is real.
• You require non-standard attestation validation, enterprise attestation policies, or device-bound credential attestation guarantees that the underlying library doesn't expose.
• You have no capacity to absorb periodic breaking upgrades. This is a library tracking a fast-moving upstream; 6.0.0 is evidence that majors will land and require code changes. If you cannot staff that, a managed service is the honest answer.
• Passkeys are a small slice of a much larger identity requirement (SCIM, SSO, directory sync) — buy a platform, don't assemble one.

How to Pitch It (Stakeholders)

To executives: Passkeys are becoming table stakes in consumer and enterprise auth — they're phishing-resistant, faster than passwords, and cut reset volume. This package lets our Laravel app add them without building cryptography ourselves, so the cost is integration and UX, not R&D. The 6.0.0 release is routine upstream alignment: it retires a deprecated API and modernizes credential handling. No customer-facing change, but it does mean a planned migration sprint for teams that customized credential storage. Recommendation: treat the upgrade as scheduled maintenance, and treat passkey adoption as a separate product bet with its own success metrics (sign-in completion rate, reset-ticket volume, MFA coverage).

To engineering: 6.0.0 is a breaking major. The credential object returned by the library is now CredentialRecord rather than the deprecated PublicKeyCredentialSource, tracking webauthn-lib 5.3. Anyone with custom authenticator repositories, serialized credential payloads, type-hinted services, or tests asserting on the old class needs a migration pass — including any persisted serialization format, which is the highest-risk area and needs a backward-compatibility check on existing enrolled credentials. Audit for deprecation warnings before upgrading. Sequence it as: inventory customizations → verify stored credential round-trip → upgrade on a branch → confirm existing passkeys still authenticate before rollout. Pin the version in composer.json and budget this as a recurring line item, because upstream majors will keep coming.
