samyakbardiya / dmenu_bw

A dmenu wrapper for bitwarden-cli written in POSIX shellscript.

dmenu_bw

A minimal Bitwarden GUI written in POSIX shellscript.

I created dmenu_bw as a hotkeyed password manager for minimal window manager desktop sessions. It is highly inspired by the mouseless workflow of tiling window managers, allowing the rapid lookup, creation, and editing of Bitwarden vault items. The goal of dmenu_bw is to provide the same capabilities as the official Bitwarden client but without the Electron dependency.

Features:

• Fast 🔥🔥🔥
• Light (no Electron)! 🪶
• Copy passwords!
• Create vault items!
• Edit vault items!

Dependencies

• bitwarden-cli (aur)
• dmenu
• yad
• xclip
• libnotify (optional)

Usage

Run dmenu_bw.

If you are not logged in, it will ask for your username and password.

If you are logged in, but your session is locked, it will ask for your password. See configuration/sessionKeyFile

If login was successful or your session was already unlocked, it will show the main list of actions create, logout, sync, and the list of vault items.

• Copying Passwords
• Creating Vault Items
• Editing Vault Items
• Deleting Vault Items
• Syncing Vault Items
• Logging Out

Copying Passwords

Select an item from the main list and select copy. See configuration/copyCmds.

Creating Vault Items

Select create from the main list. Passwords are automatically generated based on the passwordGenCmd option. See configuration/passwordGenCmd.

time: 4.33s

Editing Vault Items

Select an item from the main list and select edit. See configuration/editCmd.

time: 5.16s

Deleting Vault Items

Select an item from the main list and select delete.

Syncing Vault Items

Select sync from the main list.

Logging Out

Select logout from the main list.

Configuration

dmenu_bw looks for ${XDG_CONFIG_HOME:-${HOME}/.config}/dmenu_bw/config.json. If no file is found, the default configuration is used.

• Default Configuration
• copyCmds
• dmenuOpts
• editCmd
• passwordGenCmd
• sessionKeyFile

Default Configuration

{
    "copyCmds": {
        "login": {
            ".login.username": [
                "echo \"$value\" | xclip -i -selection clipboard"
            ],
            ".login.password": [
                "echo \"$value\" | xclip -i -selection primary"
            ]
        },
        "securenote": {},
        "card": {},
        "identity": {}
    },
    "dmenuOpts": "-i -l 10",
    "editCmd": "xterm -e nano",
}

Notice that the default behavior is to copy the username to clipboard and password to primary at the same time. This is so you can paste your username and password time without having going back and forth to the password manager.

Hint: use middle mouse click to paste your primary clipboard, or use sxhkd to paste your primary clipboard with Super + v

mod4+v
    sleep 0.25 &&
    xdotool type --clearmodifiers "$(xclip -o -selection primary)"

copyCmds

Contains objects for each of the Bitwarden item types. Each object contains an array named after the property of said item. The array contains commands to be evaluated where $value is the value of the property of said item.

e.g. copy usernames and passwords to the clipboard and tmux:

"login": {
    ".login.username": [
        "echo \"$value\" | xclip -i -selection clipboard",
        "tmux set-buffer \"$value\""
    ],
    ".login.password": [
        "echo \"$value\" | xclip -i -selection primary",
        "tmux set-buffer \"$value\""
    ]
}

e.g. output identities to a file:

"identity": {
    ".": [
        "echo \"$value\" > /tmp/bar"
    ]
}

dmenuOpts

Options to pass to the dmenu command.

editCmd

Editing vault items with yad is not yet supported. Vault items can be edited by passing the raw JSON item to your editor command.

e.g. edit items with st and nvim

"editCmd": "st -e nvim"

passwordGenCmd

The command for automatically generating new login passwords.

e.g. generate a random 16-character password

"passwordGenCmd": "tr -dc 'a-zA-Z0-9!@#$%^&*()-=_+[]~{}|;:,./<>?' < /dev/urandom | head -c 16"

sessionKeyFile

The path of the file to output your BW_SESSION shell export whenever a new session key is generated. If you like this method of session persistence, simply set sessionKeyFile and source that file in your shell's rc.

config.json:

"sessionKeyFile": "/home/foo/.cache/bwsession"

.xprofile/.bashrc/.zshrc:

source /home/foo/.cache/bwsession
