Passwordless.dev review
A low-cost passkey toolkit with biometrics, APIs, SDKs, and self-hosting options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Passwordless.dev is Bitwarden’s developer toolkit for adding FIDO2 WebAuthn passkey registration and sign-in to websites, native applications, and enterprise systems. It suits developers building customer-facing authentication or workforce authentication, especially teams that want platform biometrics such as Face ID, fingerprints, and Windows Hello. The product includes a JavaScript client library, REST APIs, an administrative console, and support for web, iOS, Android, and API deployments.
Pricing is structured across three annual plans. Free costs $0 per user per month and includes the FIDO2 WebAuthn passkey toolkit, support, and documentation access. Pro costs $0.05 per user per month and adds unlimited apps, unlimited console administrators, a dedicated SLA, and prioritized support. Enterprise costs $3 per user per month and adds workforce authentication, support for existing authentication infrastructure, application and organizational event logs, and self-hosting beta access. The offering includes 10,000 users, making the lower tiers relevant for developers controlling authentication costs.
Its ecosystem fit is centered on developer access rather than a broad catalog of third-party integrations. Passwordless.dev supports JavaScript, C#, Java, PHP, and Python, alongside public and private backend REST APIs. Discoverable credentials and browser autofill support help cover common passkey flows, while the console manages applications, users, passkeys, usage, and billing. Cloud and self-hosted deployment options provide flexibility, but self-hosting remains in beta. Choose Passwordless.dev for focused passkey biometrics and implementation control; teams needing a wider authentication scope should consider an alternative.
