PyFxA: Python library for interacting with Firefox Accounts

https://travis-ci.org/mozilla/PyFxA.svg?branch=master

This is python library for interacting with the Firefox Accounts ecosystem.

Eventually, it is planned to provide easy support for the following features:

being a direct firefox accounts authentication client
being an FxA OAuth Service Provider
accessing attached services
helps interactions with Firefox Account servers wiht requests Authentication plugins.

But none of that is ready yet; caveat emptor.

Firefox Accounts

Currently, basic auth-server operations should work like so:

from fxa.core import Client

client = Client("https://api.accounts.firefox.com")
client.create_account("test@example.com", "MySecretPassword")

session = client.login("test@example.com", "MySecretPassword")
cert = session.sign_certificate(myPublicKey)
session.change_password("MySecretPassword", "ThisIsEvenMoreSecret")

FxA OAuth Relier

Trade the authentication code against a longer lived OAuth token:

from fxa.oauth import Client

client = Client()
token = client.trade_code("client-id", "client-secret", "code-1234")

Verify an OAuth token:

from fxa.oauth import Client
from fxa.errors import ClientError

client = Client()

try:
    profile = client.verify_token("123456...")
except ClientError:
    print "Invalid token"

print("User id", profile["user"])

Testing email addresses

There's also very basic integration with restmail.net, to allow for testing with live email addresses. It works like this:

from fxa.core import Client
from fxa.tests.utils import TestEmailAccount

# Create a testing account using an @restmail.net address.
acct = TestEmailAccount()
client = Client("https://api.accounts.firefox.com")
session = client.create_account(acct.email, "MySecretPassword")

# Verify the account using the code from email.
acct.fetch()
for m in acct.messages:
    if "x-verify-code" in m["headers"]:
        session.verify_email_code(m["headers"]["x-verify-code"])

...

# Destroy the account once you're done with it.
acct.clear()
client.destroy_account(acct.email, "MySecretPassword")

Passing tokens and assertions to other applications

PyFxA provides a fxa-client that you can use to export Bearer Tokens and Browser ID assertions.

Get a Bearer Token for an existing account

fxa-client --bearer --auth you@domain.tld \
    --account-server https://api.accounts.firefox.com/v1 \
    --oauth-server https://oauth.accounts.firefox.com/v1

Please enter a password for you@domain.tld:

# ---- BEARER TOKEN INFO ----
# User: you@domain.tld
# Scopes: profile
# Account: https://api.accounts.firefox.com/v1
# Oauth: https://oauth.accounts.firefox.com/v1
# ---------------------------
export OAUTH_BEARER_TOKEN="3f5106b203c...b728ef93fe29203aad44ee816a45b2f2ff57a6aed7a3"

Create a new account Bearer Token on stage

fxa-client --bearer --create --prefix hello

# ---- BEARER TOKEN INFO ----
# User: hello-89331eba46e970dc1686ba2dc4583fc9@restmail.net
# Scopes: profile
# Account: https://api-accounts.stage.mozaws.net/v1
# Oauth: https://oauth.stage.mozaws.net/v1
# ---------------------------
export OAUTH_BEARER_TOKEN="ecb5285d59b28e6768fe60d76e6994877ffb16d3232c...72bdee05ea8a5"

Create a new account BrowserID assertion on stage

fxa-client --browserid --create --audience https://token.stage.mozaws.net/ --prefix syncto
# ---- BROWSER ID ASSERTION INFO ----
# User: syncto-5bcf63598bf6026a6833035821742d3e@restmail.net
# Audience: https://token.stage.mozaws.net/
# Account: https://api-accounts.stage.mozaws.net/v1
# ------------------------------------
export FXA_BROWSERID_ASSERTION="eyJhbGciOiJSUzI1NiJ9.eyJw......VNKcPu6Uc9Y4pCuGcdM0UwaA"
export FXA_CLIENT_STATE="abaa31cc3b16aaf6759f2cba164a54be"

With Requests

Using Firefox Account BrowserID with Requests

You can use the FxABrowserIDAuth to build the BrowserID assertion:

from fxa.core import Client
from fxa.plugins.requests import FxABrowserIDAuth

email = acct.email
password = "MySecretPassword"

raw_resp = requests.get('https://token.services.mozilla.com/1.0/sync/1.5',
                        auth=FxABrowserIDAuth(email, password,
                                              with_client_state=True))

raw_resp.raise_for_status()
resp = raw_resp.json()
user_id = resp['uid']

Using Firefox Account Bearer Token with Requests

You can use the FxABearerTokenAuth to build the Bearer Token:

from fxa.core import Client
from fxa.plugins.requests import FxABearerTokenAuth

email = acct.email
password = "MySecretPassword"

raw_resp = requests.get('https://profile.accounts.firefox.com/v1/profile',
                        auth=FxABearerTokenAuth(email, password,
                                                ['profile'], client_id))

raw_resp.raise_for_status()
resp = raw_resp.json()
user_id = resp['uid']

With HTTPie

Using Firefox Account BrowserID with HTTPie

You can use the httpie plugin provided with PyFxA to build the BrowserID request:

BID_WITH_CLIENT_STATE=True \
    http GET https://token.services.mozilla.com/1.0/sync/1.5 \
    --auth-type=fxa-browserid --auth "email:password" -v

You can configure the audience by settings the BID_AUDIENCE environment variable.

You can also compute the Token Server client state using the BID_WITH_CLIENT_STATE environment variable.

Using Firefox Account Bearer Tokens with HTTPie
