What Passwordless.dev is
Passwordless.dev is an API framework for teams building passkey authentication for customers, users, or workforce members. It uses open-source code and modern browser standards to create FIDO2 WebAuthn applications, including sign-in flows with Face ID, fingerprint, and Windows Hello. It is designed to work with common authentication solutions, so teams can adopt passkeys without recoding or replacing them. A dedicated console manages passkeys, applications, and users. The product can also support password-free access for internal team members to enterprise systems and applications. Bitwarden describes developers building passkey authentication for websites and applications as the intended users, and says third parties assess the product's open-source code, documentation, and processes. Supported platforms include 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; users above that are billed at $0.01 per user.
