A Python client and wrapper around the 1Password CLI.

Project description

OnePassword python client

PyPi release CodeQL

Python client around the 1Password password manager cli for usage within python code and Jupyter Notebooks. Developed by Data Scientists from Jamf.

Supported versions

There are some of the pre-requisites that are needed to use the library. We automatically install the cli for Mac and Linux users when installing the library. Windows users see below for help.

  • 1Password App: 8+
  • 1Password cli: 2+
  • Python: 3.10+

Operating systems

The library is split into two parts: installation and client in which we are slowly updating to cover as many operating systems as possible the following table should ensure users understand what this library can and can't do at time of install.

MacOS Linux
Fully supported Y Y
CLI install Y Y
SSO login Y Y
Login via App Y Y
Biometrics auth Y Y
Password auth Y Y
CLI client Y Y
Service account Y Y


pip install 1password

If you have issues with PyYaml or other distutils installed packages then use:

pip install --ignore-installed 1password

You are welcome to install and manage op yourself by visiting the CLI1 downloads page to download the version you require and follow instructions for your platform as long as it's major version 2.

The above commands pip commands will check op is present already and if not will install the supported op cli plus the python client itself. This is currently fixed at op version 1.12.5 to ensure compatibility. If you wish to use a higher version of op you can by following this guide, however note that we cannot ensure it will work with our client yet.

MacOS users will be prompted with a separate installation window to ensure you have a signed version of op - make sure to check other desktops that the installer might pop up on.

Optional pre-requisites


This utility is used to create a unique guid for your device but this isn't a hard requirement from AgileBits and so if you see base32: command not found an empty string will be used instead, and the client will still work fully.

If you really want to, you can make sure you have this installed by installing coreutils. Details per platform can be found here:

Basic Usage

Since v2 of the cli it is advised to connect your CLI to the local app installed on the device, thus removing the need for secret keys and passwords in the terminal or shell. Read here on how to do that:

An added extra for Mac users is that you can also enable TouchID for the app and by linking your cli with the app you will get biometric login for both.

Once this is done any initial usage of the cli, and our client will request you to authenticate either via the app or using your biometrics and then you can continue.

We are sure there are use cases where the app cannot be linked and hence a password etc is till required so this functionality is still present from our v1 implementation and can be described below

Password authentication

On first usage users will be asked for both the enrolled email, secret key and password. There is also verification of your account domain and name.

For all following usages you will only be asked for a password.

You will be given 3 attempts and then pointed to reset password documentation or alternatively you can restart your kernel.

No passwords are stored in memory without encryption.

If you have 2FA turned on for your 1Password account the client will ask for your six digit authenticator code.

from onepassword import OnePassword
import json

op = OnePassword()

# List all vaults 

# List all items in a vault, default is Private

# Get all fields, one field or more fields for an item with uuid="example"
op.get_item(uuid="example", fields="username")
op.get_item(uuid="example", fields=["username", "password"])

Service Accounts

We also support authentication using Service accounts, however these are not interchangeable with other auth routes and hence other accounts i.e. this token based authentication will take precedence over any other method. If you wish to use multiple account types, for now you will need to design this workflow yourself by clearing out the OP_SERVICE_ACCOUNT_TOKEN using unset OP_SERVICE_ACCOUNT_TOKEN before re-authenticating with your preferred account.

To use a service account make sure to fulfil the requirements here: and note that not all of the CLI commands are supported at this time.

Also note that your service account will only have access to certain vaults. In particular it will not be able to see the Shared or Private vaults in any account. In our client this means you must always use the vault option.

Once you have fulfilled all the requirements, namely export OP_SERVICE_ACCOUNT_TOKEN=<your token>, you can then use our client with:

from onepassword import OnePassword

op = OnePassword()

Input formats

To be sure what you are using is of the right format

  • Enrolled email: standard email format e.g.
  • Secret key: provided by 1Password e.g. ##-######-######-#####-#####-#####-#####
  • Account domain: domain that you would login to 1Password via browser e.g.
  • Account name: subdomain or account name that cli can use for multiple account holders e.g. example


The GitHub action will run a full build, test and release on any push. If this is to the main branch then this will release to public PyPi and bump the patch version.

For a major or minor branch update your new branch should include this new version and this should be verified by the code owners.

In general, this means when contributing you should create a feature branch off of the main branch and without manually bumping the version you can focus on development.

CLI coverage

Full op documentation can be found here:

The below is correct as of version 0.3.0.


This is the set of commands the current python SDK covers:

  • create: Create an object
    • document
  • delete: Remove an object
    • item: we use this method to remove documents but now there is a new delete document method
  • get: Get details about an object
    • document
    • item
  • list: List objects and events
    • items
    • vaults
  • signin: Sign in to a 1Password account
  • signout: Sign out of a 1Password account

This is what still needs developing due to new functionality being released:

  • add: Grant access to groups or vaults
    • group
    • user
  • completion: Generate shell completion information
  • confirm: Confirm a user
  • create: Create an object
    • group
    • user
    • item
    • vault
  • delete: Remove an object
    • document
    • user

  • Align response types into JSON / lists instead of JSON strings
  • Ensure full and matching functionality of CLI in python
    • add
    • confirm
    • create
