Self-Hosted Password Managers: Bitwarden (Vaultwarden) vs KeePass

Introduction

In the quest for privacy-first digital security, self-hosting your own password manager is one of the most empowering moves you can make. Two names frequently rise to the top of the list: Bitwarden, or its lighter community fork Vaultwarden, and KeePass, the venerable, offline password manager that’s been around for decades.

This in-depth comparison explores Bitwarden/Vaultwarden vs KeePass, tailored for both privacy-conscious beginners and advanced self-hosters.

1. Core Philosophy & Design

DeploymentDocker container, VPS, home serverNative app (Windows/Linux/macOS)
Initial SetupWeb installer, config file, Docker ComposeDownload and run binary
Beginner SetupEasy with Vaultwarden’s prebuilt imagesSimple for local use, no server needed
Platform SupportWeb, desktop, mobile appsWindows native, cross-platform via forks

Beginner Tip: Vaultwarden on a Raspberry Pi is a popular and accessible home setup.

3. User Interface & Accessibility

FeatureBitwarden / VaultwardenKeePass
Web InterfaceYes (full-featured)No
Mobile AppsOfficial and community apps availableCommunity apps (e.g. KeePassDX, KeePass2Android)
Browser ExtensionsYes (Chrome, Firefox, Edge, etc.)Limited, via third-party plugins
UX ExperienceModern and polishedFunctional, but dated

Observation: Bitwarden’s UI feels more intuitive for those used to modern password managers like LastPass or 1Password.

4. Security Model & Encryption

Encryption AlgorithmAES-256, PBKDF2AES/Rijndael, ChaCha20
Master PasswordYesYes
2FA SupportTOTP, WebAuthn, email (Vaultwarden)Plugin-based
Database EncryptionFull vault encryptionEncrypted KDBX database file
Security AuditsBitwarden is audited; Vaultwarden inherits codebaseKeePass: Not regularly audited

Advanced Users: KeePass allows full control over keyfiles, composite master keys, and offline-only use for total isolation.

5. Sync, Sharing & Multi-user

FeatureBitwarden / VaultwardenKeePass
Cross-device SyncBuilt-in (via server)Manual (via file sync, e.g. Nextcloud)
User SharingOrganizations, shared vaultsNot built-in; file-based sharing only
Self-HostingCore featureOptional (share database via cloud)
Offline FunctionalityOptional, depending on clientDefault

Insight: For teams or households, Vaultwarden offers collaborative features that KeePass lacks natively.

6. Extensibility & Plugins

Plugin EcosystemMinimalExtensive (auto-type, YubiKey, etc.)
Custom FieldsYes (secure notes, TOTP, attachments)Yes
ScriptingAPI + CLI toolsKeePassRPC, PowerShell scripts

Power Users: KeePass is a tinkerer’s paradise. Vaultwarden trades off some extensibility for modern usability.

7. Privacy & Network Behavior

AspectBitwarden / VaultwardenKeePass
Network DependencyRequires serverNo (fully offline)
TelemetryNone (Vaultwarden), minimal in BitwardenNone
Cloud UsageOptional (self-hosted disables cloud)Never

Privacy Verdict: KeePass wins for full air-gap security. Vaultwarden is still excellent when self-hosted.

8. Use Cases & Recommendations

Use CaseBest Fit
Individual self-hoster with multiple devicesVaultwarden
Air-gapped setup, highest privacyKeePass
Shared vaults or small team collaborationVaultwarden
Advanced customization (e.g., YubiKey login)KeePass (with plugins)

9. Final Verdict

Choose Vaultwarden (Bitwarden) if:

  • You want a modern UI, browser extension support, and mobile sync.
  • You’re hosting for a household or small team.
  • You prefer the convenience of web access with strong encryption.

Choose KeePass if:

  • You want maximum security in offline mode.
  • You enjoy scripting, plugins, and control over every detail.
  • You’re comfortable managing files manually (e.g. with Nextcloud sync).

Example Configurations

  • Vaultwarden on Docker with Caddy reverse proxy and TOTP enabled.
  • KeePass synced via Syncthing across devices with auto-type shortcuts and a YubiKey for extra protection.
