Bitwarden

ApplicationBitwarden Inc.

Also called bit warden, bitwarden vault

Bitwarden Inc.Security

An open-source password manager with a desktop vault. The window is Bitwarden.exe. You can use their cloud or host the server yourself. It is not LastPass and not 1Password.

What you need to know

Bitwarden is open source and can be self-hosted. LastPass is not that product.

Bitwarden.exe is the Windows vault. You can use Bitwarden's cloud or host the server. 1Password is a paid closed vault with Watchtower. KeePass stores a local kdbx. LastPass is an older cloud vendor people leave after 2022.

What is it?: Open-source vault. Self-host is optional
Same as LastPass?: No. Different vendor and server story
Same as 1Password?: No. 1Password is paid and not self-hosted

Feex says

If someone said every password manager is the same cloud blob, I would stop them. Bitwarden can be self-hosted. 1Password cannot. KeePass is a local kdbx with no official Bitwarden server. LastPass is a different vendor with a different breach history.

What is Bitwarden?

Bitwarden is an open-source password manager. Bitwarden.exe is the Windows desktop vault. Self-hosting the server is optional and official.

If you have never used it

If you want a vault you can audit and optionally host yourself, Bitwarden is that product. Download the Windows app from bitwarden.com/download. Bitwarden.exe is the desktop client. The vault can live on bitwarden.com or on a server you run. It is not LastPass, not 1Password Watchtower, and not a local-only KeePass kdbx file unless you chose that elsewhere.

What is it used for?

Cloud or self-hosted vault

Logins sync through Bitwarden's service or a server you host. 1Password does not sell a self-host option like this.

Desktop unlock and fill

Bitwarden.exe unlocks the vault on Windows. Browser extensions talk to that vault. LastPass is a different cloud vendor.

Organizations and sharing

Paid orgs share items. That is Bitwarden Organizations, not KeePass's local kdbx email dance.

Who is it for?

People who want an open-source vault with an official Windows app
Users who self-host Bitwarden and still use Bitwarden.exe as the client
Anyone leaving LastPass who should not assume 1Password is the same license

Current status

Actively developed. This article is the Windows desktop client, not the browser extension alone.

How old is it?

Bitwarden launched in 2016 as an open-source vault. It is younger than KeePass (2003) and 1Password (2006). Current Windows builds are Electron. A 2016 early web vault screenshot is not the current desktop app.

Versions

Major channels first. Exact build numbers are not all verified here.

Desktop app

Browser extension

Self-hosted server

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	Windows 10 or Windows 11, per Bitwarden desktop downloads
RAM	The Electron vault is a few hundred MB class. The secrets are small

Resource profile

CPU demand: Low except during unlock and import
Network demand: Sync when the vault is online

Installed processes

These executables belong to this product when it is installed.

Installed processes
Bitwarden.exe	Desktop vault window

Startup components

Bitwarden.exe can start at logon if you allow the tray. That is a Bitwarden setting, not a Windows service you must keep.

File locations

Common Bitwarden locations
Typical install	C:\Program Files\Bitwarden\

File formats

JSON exportCSV importencrypted vault

Common problems

People treat it as LastPass

Different company, different server, optional self-host. Importing a LastPass CSV is a migration, not the same app.

Desktop app versus only the extension

Bitwarden.exe is the Windows vault. An extension-only setup is still Bitwarden but not this process.

Getting unstuck

Install from bitwarden.com/download

A "Bitwarden Pro" third-party exe is not the vendor. The official client is Bitwarden.exe.

Confirm cloud versus self-host URL

The desktop app asks which server. vault.bitwarden.com is the vendor. A LAN URL is your host. 1Password has no this field.

Unlock, then check the extension

Locked Bitwarden.exe will not fill. That is a vault lock, not a Windows Credential Manager failure.

Alternatives

1Password if you want a paid closed vault and Watchtower. KeePass or KeePassXC if you want only a local kdbx. LastPass if you already live there and accept that vendor.

Official help and downloads

Start with the vendor. Random exe sites are not a support channel.

Official contacts

Self-host	bitwarden.com/help/self-host-an-organization/ Optional server you run. 1Password does not offer this

Related hardware

The desktop vault is light. Sync needs a network. Self-host hardware is a server question, not this PC's GPU.

Technical details

Vendor version numbers change. This article does not pin a build.
