Frequently Asked Questions

Is Bitwarden truly free without limitations?

Yes, Bitwarden's free plan includes unlimited password storage across unlimited devices with full autofill functionality. Premium ($10/year) adds optional features like file storage, TOTP authenticator, and priority support but isn't required for core password management.

Can I host Bitwarden on my own server?

Yes, Bitwarden supports complete self-hosting through Docker containers or direct server installation. Self-hosted instances require PostgreSQL database, SSL certificates, and ongoing maintenance but provide complete data ownership and infrastructure control.

How is Bitwarden free if security requires constant development?

Bitwarden uses open-source model where community contributions supplement paid premium tier ($10/year) revenue. This model enables free core functionality while premium features fund ongoing development and infrastructure.

Are browser extensions subject to vendor restrictions?

Bitwarden extensions function through official app stores (Chrome Web Store, Firefox Add-ons, Safari App Store) complying with vendor policies. The open-source nature ensures extension code transparency preventing vendor-level restrictions on functionality.

Does Bitwarden collect usage analytics?

No, Bitwarden minimizes data collection implementing zero-knowledge architecture. The service cannot access credentials or vault contents; cloud logs track only authentication and sync operations without analyzing password patterns or usage.

Can I migrate from Bitwarden to another password manager?

Yes, Bitwarden supports exporting vault as unencrypted JSON or CSV format compatible with other password managers. Alternative managers can then import Bitwarden exports preserving all credential data during migration.
