Bitwarden vs KeePassXC vs Proton Pass — Password Managers Compared

Almost everyone uses a password manager by now, but choosing which one is the right one still trips people up. The three strongest candidates all take different approaches to the same job. Bitwarden is the polished cloud-synced favourite with a famously generous free tier. KeePassXC is the fully offline, local-database purist. Proton Pass is the privacy-focused newcomer from the Swiss Proton house, built around end-to-end encryption and email aliases. Here’s how they stack up and which one fits the way you actually work.

1. Bitwarden — The Cloud-Synced All-Rounder

Bitwarden is the closest thing the open source world has to a default password manager. It syncs your vault across every device through its own servers, but the whole thing — client and backend — is open source and can be self-hosted if you want the data entirely on your own infrastructure.

• End-to-end encryption — AES-256 with Argon2id key derivation, with optional biometric unlock on mobile and desktop.
• Unlimited free plan — unlimited devices and password sharing on the free tier, which is rare among cloud password managers.
• Self-hosting option — deploy the entire Vaultwarden-compatible backend on your own server if you don’t want your vault on Bitwarden’s cloud.
• Modern auth — passkey support and built-in TOTP for two-factor codes, plus breach monitoring against known password leaks.

It’s the strongest all-rounder: easy to hand to a non-technical user, yet deep enough for tinkerers who want to control the server side. See the full Bitwarden listing.

2. KeePassXC — The Fully Offline Purist

KeePassXC takes the opposite stance: there is no cloud, no account, no server. Your passwords live in one encrypted database file that stays entirely on your devices, and you’re responsible for syncing it yourself if you want to use it on more than one machine.

• Local storage — one encrypted .kdbx database file under your control, with nothing stored remotely.
• Choice of encryption — AES-256, Twofish and ChaCha20 ciphers, all backed by Argon2/KDF.
• Auto-Type — automated form filling directly into apps, with browser integration via dedicated extensions.
• Built-in extras — a password generator and TOTP code generation right inside the app, so no separate authenticator is needed.

It rewards a security-first mindset and never phones home, but you own the sync problem: offline databases don’t move between devices by themselves. See the full KeePassXC listing.

3. Proton Pass — The Privacy-First Swiss Newcomer

Proton Pass comes from Proton, the Swiss company behind Proton Mail and Proton VPN. Every credential is encrypted on your device before it reaches Proton’s servers — and because it’s built in Switzerland, your data sits behind some of the world’s strongest privacy laws.

• End-to-end encryption — passwords, notes and identities are encrypted on-device, so Proton can never read them.
• Hide-my-email aliases — generate unlimited random email aliases to keep your real address private and block spam.
• Built-in 2FA — store TOTP codes alongside logins, no separate authenticator app required.
• Passkey support — create and store passkeys for passwordless, phishing-resistant logins.
• Secure sharing — share individual vaults with family or teams via fine-grained permissions.

Proton Pass is the integration play: if you already live in Proton’s ecosystem, it slots in naturally. Note that Proton Pass is not fully open source — the core is available, but it’s a freemium service with paid plans for advanced features. See the full Proton Pass listing.

Which One Should You Pick?

Choose Bitwarden if: you want a zero-friction, cross-device password manager that just works for everyone in the household, with the option to self-host later.

Choose KeePassXC if: you’re privacy-paranoid, want maximum offline control, and are comfortable managing your own database and sync.

Choose Proton Pass if: you’re already in the Proton ecosystem and want tight integration with aliases, 2FA and a Swiss jurisdiction on your side.

The Bottom Line

All three are excellent, and the honest answer is that the best one depends on your threat model and workflow. Bitwarden is the best default for most people — generous free tier, polished, open source. KeePassXC is the best choice for maximum independence and offline control. Proton Pass is the best fit for Proton users who want privacy-forward convenience. And there’s nothing wrong with Bitwarden self-hosted plus KeePassXC on the devices that matter most.
