Bitwarden ou KeePass : une bonne alternative sous Linux ?

Bitwarden, alternative Linux à KeePass

Mis à jour le 19 octobre 2026

Notre avis

Bitwarden is a good replacement for KeePass if you prioritize cross-device sync, browser integration, and ease of use over full local control. It offers strong encryption and open-source clients, making it trustworthy for most users. However, privacy-focused users who prefer completely offline, file-based storage without relying on any cloud service—even if encrypted—will still favor KeePass. Bitwarden works well for people wanting seamless access across phones, tablets, and computers without managing files manually.

Bitwarden on multiple devices

Ce qui fonctionne pareil

Both use AES-256 encryption for stored passwords
Open-source clients allow public code review and audits
Support password generation with customizable rules
Offer secure storage for logins, notes, and 2FA secrets
Work across multiple platforms including Linux, Windows, and mobile

Ce qui change

Bitwarden relies on account-based syncing via cloud or self-hosted server, while KeePass uses direct file access
KeePass has no mandatory account or sync infrastructure
Bitwarden lacks native support for .kdbx file format without conversion
KeePass offers more granular database organization and plugins
Bitwarden's desktop app requires Flatpak or third-party packages on Linux

Ouvrir vos fichiers KeePass

Bitwarden does not natively open .kdbx files used by KeePass. However, you can import a KeePass database by first unlocking it in KeePass and exporting to CSV or using the Bitwarden import tool. The import preserves folders, usernames, passwords, URLs, and notes. After import, entries are stored in Bitwarden’s encrypted vault format. Direct .kdbx syncing or opening is not supported, so ongoing file-based sharing with KeePass users requires manual re-imports.

Questions fréquentes

Can I use Bitwarden without an internet connection?

Yes, the desktop and mobile apps cache your vault locally and work offline. Syncing and access from new devices require internet later.

Is my data safe in Bitwarden’s cloud?

Your vault is encrypted locally with AES-256 before syncing. Bitwarden cannot read your passwords—even if they wanted to. Your master password is never sent to their servers.

Can I self-host Bitwarden?

Yes, Bitwarden offers a self-hostable server (Vaultwarden is a popular open alternative). This gives you full control over where your encrypted data resides.
