Yes. Bitwarden's free tier is extremely generous: unlimited passwords, unlimited devices, free sync across all platforms, and open-source code. Premium adds 1GB encrypted file storage, advanced 2FA options, vault health reports, and TOTP authenticator for $10/year.

Will I lose my passwords if I cancel Premium?

No. All your passwords remain in your vault on the free tier. Bitwarden Free supports unlimited passwords and unlimited devices. You only lose Premium-specific features like file attachments and health reports.

Is Bitwarden open source?

Yes. Bitwarden is fully open-source and has been independently audited multiple times. You can self-host your own Bitwarden server if you prefer not to use the cloud service.

引き止め対策

Great news — Bitwarden's free tier is one of the most generous in the industry: unlimited passwords, unlimited devices, and full sync at no cost. You're really just losing Premium features like file attachments and vault health reports. At only $10/year for Premium, it's the most affordable password manager upgrade available. Are you sure you want to cancel rather than stay on the free tier?
