Santa Barbara, California, USA
What it is
Passwordless.dev is an API framework for developers building passkey authentication for websites and applications. It uses open-source code and browser standards for FIDO2 WebAuthn flows, including Face ID, fingerprint, and Windows Hello. The product is designed to work with common authentication solutions, so teams can adopt passkeys without replacing or recoding those systems. A console manages passkeys, applications, and users, and the service can support password-free workforce access to enterprise systems. It supports web browsers, Android 9+, iOS, and REST API, with SDKs for JavaScript, C#, Java, PHP, and Python. The Free plan costs nothing and covers up to 10,000 users, one app per organization, one console administrator, support, and documentation access. Pro costs $0.05 per user per month for the first 10,000 users, with users above that billed at $0.01 per user. Enterprise lists workforce authentication and self hosting as a beta feature. Bitwarden says third parties assess the product's open-source code, documentation, and processes.
