What Passwordless.dev is
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. The service is intended to work with common authentication solutions, allowing teams to add passkeys without recoding or replacing those systems. A dedicated console manages passkeys, applications, and users, and the framework can also support password-free workforce access to enterprise systems and applications. It supports web browsers, Android 9+, iOS, and REST API, with SDKs for JavaScript, C#, Java, PHP, and Python. The Free plan supports up to 10,000 users, one app per organization, and one console administrator. Pro costs $0.05 per user per month for the first 10,000 users, with additional users billed at $0.01 per user. Enterprise lists self-hosting as a beta feature. Bitwarden says third parties assess its open-source code, documentation, and processes.
