Flexpass

A simple yet flexible library (and command-line application) to access passwords from various backends (GPG/pass, Linux SecretService, Windows Credentials Manager, etc).

See full documentation and API reference on Read the Docs.

Installation

Flexpass package is available on PyPI.org:

pip install flexpass

Usage

Flexpass may be used as a library in your Python code:

import flexpass
flexpass.list_passwords()
flexpass.set_password(name, password)
flexpass.get_password(name)
flexpass.delete_password(name)

Flexpass may also be invoked as a command-line application (flexpass executable is installed with the package):

flexpass --help

Flexpass may also be invoked as a Python module:

python -m flexpass --help

Main features

This library provides read and write access to passwords, identified by a name, through the following functions:

def get_password(name: str) -> str|None:
    ...

def set_password(name: str, password: str, **options) -> None:
    ...

def delete_password(name: str) -> bool:
    ...

def list_passwords() -> list[PasswordInfo]:
    ...

Function get_password scans all registered backends, ordered by decreasing priority, and returns the first password found with the given name.

Function set_password sets the given password in the writable backend with the highest priority.

Function delete_password deletes the given password in all writable backends where the password was set. Returns True if the password was deleted from at least one backend, False otherwise.

Function list_passwords lists all available passwords.

Access to passwords is also possible for a specific backend, by using this backend method. Examples:

backend = get_backend('gpg')
backend.get_password('my/password')

Example of invokation of flexpass command-line application with the list command (which is the default command when no argument is given). It retrives passwords using function list_passwords and format the results:

N.B.: by default, names are displayed truncated to 40 characters. Add option --full to disable truncation.

Backends

The following backends are included in Flexpass package:

Name	Priority	Description
gpg	80	GPG encrypted files following the layout defined by pass, the standard unix password manager.
secretservice	60	Secret Service D-Bus API, a FreeDesktop.org standard usually accessed through libsecret and its frontends (secret-tool, Gnome Keyring, KDE Wallet Manager or KeyPassXC).
wincred	50	Windows Credential Manager, the password manager integrated in Windows.

These backends are planned to be added later (ROADMAP):

Name	Priority	Description
dockersecrets	30	Docker Compose secrets, made available in the containers at path /run/secrets/{name} or in /run/secrets/misc (or at local path secrets/{name}.txt or in secrets/misc.ini: usefull during development). Read-only.
dir	20	Unencrypted files in a root directory (by default /root/passwords).
env	10	Environment variables. Read-only.

Custom backends may be registered in your Python code using the register_backend function. Example:

from flexpass import register_backend
register_backend(MyCustomBackend, priority=70)

Pre-defined priorities may be modified by calling the register_backend with the new priority value. Example:

register_backend(WincredBackend, priority=5, replace_if_exists=True)

Credits

Inspired by:

• pass: the standard unix password manager based on GPG. It has very few requirements and may be installed on most workstations and servers. It is cross-platform because only GPG is actually required to read or write passwords.
• keyring: a most wildly used Python library to access passwords.
