Bitwarden vs Passwordless.dev

Bitwarden is a password manager for individuals and organizations to manage and share online information. Accounts can store passwords, notes, credit cards, and identities, and include passkey management plus a username and password generator. Bitwarden says vault data is end-to-end encrypted and only the user's master password can decrypt it. Bitwarden Send transmits text and files to anyone, including people who do not use the service. Apps include a web app, browser extensions, desktop applications for Windows, macOS, and Linux, and mobile apps for Apple and Android. The Free plan includes basic password management, unlimited devices and passwords, and sharing with another user at no charge. Premium is $1.65 a month billed annually; Families is $3.99 a month billed annually for up to six users. Teams costs $4 per user per month billed annually, and Enterprise is $6 per user per month billed annually. The company says it conducts annual source code audits and penetration tests, and lists ISO 27001, SOC 2, SOC 3, and HIPAA credentials. One platform-specific limitation: the F-Droid build lacks live-sync push notifications, so manual vault syncing is required.

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.
