Bitwarden vs fido2-lib

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.
