Synchronization

The --sync options control when the current operation involves a synchronization with the server. If now is set, and the command makes a change, the change is synchronized before the command exits. If now is set, and the command displays a value, the local cache is synchronized before the value is shown. If now is set, and the command is otherwise successful, but synchronization fails, the command will return an error. If auto is set, and the command makes a change, the change is synchronized to the server in the background. If auto is set, and the command displays a value, the local cache is synchronized before the value is shown only if the local cache is more than 5 seconds (or LPASS_AUTO_SYNC_TIME seconds, if set) old. If no is set, the command will not interact with the server, unless there is a current upload queue being processed. Any local changes that are not synchronized with the server will exist in a queue of timestamped requests which will be synchronized on the next occurring synchronization.

The sync command forces a synchronization of the local cache with the LastPass servers, and does not exit until the local cache is synchronized or until an error occurs. Alternatively, if --background is specified, the synchronization occurs in a daemonized process.

Agent

An agent process will be spawned in the background on a first successful command, and all subsequent commands will use the agent for decryption, instead of asking a user for a password. The agent will quit after one hour, unless the LPASS_AGENT_TIMEOUT environment variable is set to an alternative number of seconds in which to quit, or 0 to never quit. If the environment variable LPASS_AGENT_DISABLE is set to 1, the agent will not be used.

Password Entry

The pinentry program, part of gpg2(1), may be used for inputting passwords if it is installed. A custom path to the pinentry program can be provided by the LPASS_PINENTRY environment variable.

If pinentry program is unavailable, or if the LPASS_DISABLE_PINENTRY environment variable is set to 1, passwords will be read from standard input and a prompt will be displayed on standard error.

The program used for inputting passwords may also be configured by setting the LPASS_ASKPASS environment variable. LPASS_ASKPASS is expected to be a binary that produces a prompt using its first command-line argument, and outputs the entered password to standard out. ssh-askpass implements this protocol, as does the following shell script:

#!/bin/bash
echo -n "$*: " >/dev/stderr
stty -echo
read answer
stty echo
echo $answer

Entry Specification

Commands that take a UNIQUENAME will fail if the provided name is used multiple times, and return an error. Commands may alternatively take a UNIQUEID, which will be the integer ID provided by LastPass for identifying entries uniquely. Commands that take either a NAME or a UNIQUEID will create a new entry if a NAME is specified and otherwise overwrite an existing entry if UNIQUEID is specified.

Logging In

The login subcommand will initialize a local cache and configuration folder, then attempt to authenticate itself with the LastPass servers, using the provided command line credentials or by interactively prompting (in the case of multifactor or an unprovided password). The --trust option will cause subsequent logins to not require multifactor authentication. If the --plaintext-key option is specified, the decryption key will be saved to the hard disk in plaintext. Please note that use of this option is discouraged except in limited situations, as it greatly decreases the security of data.

The logout subcommand will remove the local cache and stored encryption keys. It will prompt the user to confirm, unless --force is specified.

The passwd subcommand may be used to change your LastPass password: it will prompt for the old and new password and then re-encrypt all records with the newly derived key.

Viewing

The show subcommand will display a password or selected field.

By default, the site you specify with the show subcommand must exactly match the name of the site. If the --fixed-strings or -F option is set, then the show subcommand will find a site containing that exact substring; if the --basic-regexp or -G option is set, then the show subcommand will find a site matching a case-insensitive regular expression.

By default if your show subcommand matches more than one site, then the show subcommand will generate a warning and display the names of matching sites but no other information. The --expand-multi or -x option will instead show the requested information from all of the matching sites.

The ls subcommand will list names in groups in a tree structure. If the --long or -l option is set, then also list the last modification time. The -u option may be passed to show the last use (last touch) time instead, if available. Both times are in GMT.

Passing --json to show will generate json output instead of human-readable text.

In addition to using the built-in formats, both show and ls subcommands support printf-style format strings by using the --format option with the following placeholders:

A slash can be added between the % and the placeholder to indicate that a slash should be appended, only if the printed value is expanded to a non-empty string. For example, this command will properly show the full path to an account: lpass ls --format="%/as%/ag%an".

Modifying

The edit subcommand will edit the selected field. If --non-interactive is not set, the selected field will be edited using EDITOR; otherwise the command will accept data until EOF or, unless the notes field is being edited, the first new line. Please note that when editing interactively, the contents of the field may be saved on disk in tmp files or in editor swap files, depending on your system configuration.

The generate subcommand will create a randomly generated password for the chosen key name, and optionally add a url and username while inserting the generated password.

The rm command will remove the specified entry, and the duplicate command will create a duplicate entry of the one specified, but with a different ID.

Backup

The export subcommand will dump all account information including passwords to stdout (unencrypted) in CSV format. The optional --fields=FIELDLIST argument may contain a comma-separated subset of the following fields:

id, url, username, password, extra, name, fav, id, grouping, group,
fullname, last_touch, last_modified_gmt, attachpresent

The import subcommand does the reverse: accounts from an unencrypted CSV file are uploaded to the server.

It is recommended that such backups be encrypted at rest, for example by piping to and from gpg.

Shared Folder Commands

The share command and its accompanying subcommands can be used to manipulate shared folders, if available to the (enterprise or premium) user. The userls, useradd, usermod, and userdel subcommands may be used to query and modify membership of the shared folder, while the create and rm share subcommands may be used to add new, or delete existing shared folders. The normal generate and edit commands may be used to edit accounts within the shared folder.

The share limit command may be used to manipulate account access lists on the share for a specific user. Running with no arguments will display the current access levels for a user. The --add, --rm, and --clear options may be used to add to, remove from, or reset the list. Passing --allow or --deny will make the list a whitelist or blacklist, respectively.

Clipboard

Commands that take a -c or --clip option will copy the output to the clipboard, using xclip(1) or xsel(1) on X11-based systems, pbcopy(1) on OSX, or putclip on Cygwin. The command to be used can be overridden by specifying the LPASS_CLIPBOARD_COMMAND environment variable.

Color Output

The --color option controls colored output to the terminal. By default, commands will use --color=auto, in which color output is used unless the output is not a tty (for example, when passed to a pipe or file). If always is used, colors are produced regardless of the output detection. If never is used, no color escape sequences are emitted.

Configuration

lpass stores configuration in the following locations, in descending order of precedence:

All configuration may be specified via environment variables. Alternatively, a set of environment variable overrides may be specified in $LPASS_HOME/env in the form of:

VARIABLE1=VALUE1
VARIABLE2=VALUE2
...

Aliases

Default options can be specified for any command by creating command aliases. Command aliases are stored in the configuration directory (see previous section) with files named alias.command. For example, to force the ls subcommand to never use color, make an alias.ls file with the appropriate option:

echo 'ls --color=never' > ~/.config/lpass/alias.ls

Similarly, new subcommands can be created based on built-in subcommands with options. Thus,

echo 'show --password -c' > ~/.config/lpass/alias.passclip

would create a passclip subcommand that copies your password onto the clipboard.
