1Password command-line tool: Getting started

Learn how to set up and use 1Password from the command line.

Set up the command-line tool

To install the 1Password command-line tool:

  1. Download the tool for your platform and architecture. You can verify its authenticity:

  2. Move op to /usr/local/bin, or another directory in your $PATH.

  3. To verify the installation, check the version number:

     op --version

Get started with the command-line tool

The first time you use the 1Password command-line tool, you’ll need to enter your sign-in address and email address:

op signin

Then enter your Secret Key and Master Password.

After you sign in the first time, you can sign in again using your account shorthand, which is your sign-in address subdomain. op signin will prompt you for your Master Password and output a command that can save your session token to an environment variable:

op signin example

Enter the password for user at
export OP_SESSION_example="XLC6cHkeSHByBqrikXt36fdMVLLdHuoACNFUrNMuRXQ"

Hyphens (-) in a subdomain will be changed to an underscore (_).

To set the environment variable, run the export command manually, or use eval (Mac, Linux) or Invoke-Expression (Windows) to set it automatically.

On Mac and Linux:

eval $(op signin example)

On Windows:

Invoke-Expression $(op signin example)

Now that you have a session token, you can start using the tool. For example, to show all the items in your account:

op list items

Session tokens expire after 30 minutes of inactivity, after which you’ll need to sign in again.

You can use the tool to work with users, vaults, and items. For example, here’s how to upload a document to your Private vault:

op create document readme.txt --vault Private

To see a list of all the items in your Shared vault:

op list items --vault Shared

The output will show the UUIDs of the items. To get the details of an item:

op get item WestJet

You can use names or UUIDs in commands that take any user, vault, or item as an argument. Use UUIDs because they’ll never change, so you can be sure you’re always referring to the same object. It’s also faster and more efficient.

op get item nqikpd2bdjae3lmizdajy2rf6e

You can get details of just the fields you want. For one field, the tool returns a simple string:

op get item nqikpd2bdjae3lmizdajy2rf6e --fields password

For multiple fields, specify them in a comma-separated list. The tool returns a JSON object:

op get item nqikpd2bdjae3lmizdajy2rf6e --fields username,password
{"username": "wendy_appleseed", "password": "5ra3jOwnUsXVjx5GL@FX2d7iZClrrQDc"}

Parse and manipulate JSON output with jq

Every op command outputs in one of two formats: a simple string, like a UUID, or JSON. To parse and manipulate JSON output, we recommend the command-line tool jq.

To use jq to parse a Login item called “WestJet” and retrieve the password:

op get item WestJet | jq '.details.fields[] | select(.designation=="password").value'

To use jq to manipulate a Login item template, set the username value to “wendy”, and save the item in your Private vault:

On Mac and Linux:

umask 077   # Prevent others from reading your template file

op get template login | \
  jq '(.fields[] | select(.designation == "username")).value = "wendy"' > login.json
op create item login --template login.json --title "My New Item"
rm login.json

On Windows:

cd "$HOME"   # Prevent others from reading your template file

op get template login | \
  jq '(.fields[] | select(.designation == "username")).value = "wendy"' > login.json
op create item login --template login.json --title "My New Item"
rm login.json
