In their own words
Passwordless.dev
Passwordless.dev is an API framework for developers building passkey authentication for websites and applications. It uses open-source code and browser standards to create FIDO2 WebAuthn flows, including Face ID, fingerprint, and Windows Hello. Supported environments include web browsers, Android 9+, iOS, and a REST API, with SDKs for JavaScript, C#, Java, PHP, and Python. The service is designed to work with common authentication solutions, allowing teams to add passkeys without recoding or replacing existing systems. A dedicated console manages passkeys, applications, and users. Workforce authentication can provide password-free access to enterprise systems and applications. The Free plan supports up to 10,000 users, one app per organization, and one console administrator, with support and documentation access. Pro costs $0.05 per user per month for the first 10,000 users; additional users cost $0.01 per user. Enterprise costs $3.00 per user per month billed annually and adds workforce authentication, event logs, beta self-hosting, and advanced support. Pro includes prioritized support and a dedicated SLA.
