Kinto-fxa enables authentication in Kinto applications using Firefox Accounts OAuth2 bearer tokens.

N.B. This project used to be called cliquet-fxa, but was renamed to

kinto-fxa following the rename of the cliquet project to kinto.

It provides:

• An authentication policy class;
• Integration with Kinto cache backend for token verifications;
• Integration with Kinto for heartbeat view checks;
• Some optional endpoints to perform the OAuth dance (optional).
• Kinto documentation
• Issue tracker

As stated in the official documentation, Firefox Accounts OAuth integration is currently limited to Mozilla relying services.

Install the Python package:

pip install kinto-fxa

Include the package in the project configuration:

kinto.includes = kinto_fxa

And configure authentication policy using pyramid_multiauth formalism:

multiauth.policies = fxa
multiauth.policy.fxa.use = kinto_fxa.authentication.FxAOAuthAuthenticationPolicy

By default, it will rely on the cache configured in Kinto.

Fill those settings with the values obtained during the application registration:

fxa-oauth.client_id = 89513028159972bc
fxa-oauth.client_secret = 9aced230585cc0aaea0a3467dd800
fxa-oauth.oauth_uri = https://oauth-stable.dev.lcip.org
fxa-oauth.requested_scope = profile kinto
fxa-oauth.required_scope = kinto
fxa-oauth.webapp.authorized_domains = *.firefox.com
# fxa-oauth.cache_ttl_seconds = 300
# fxa-oauth.state.ttl_seconds = 3600

In case the application shall not behave as a relier (a.k.a. OAuth dance endpoints disabled):

fxa-oauth.relier.enabled = false

If necessary, override default values for authentication policy:

# multiauth.policy.fxa.realm = Realm

Use the OAuth token with this header:

Authorization: Bearer <oauth_token>

notes

If the token is not valid, this will result in a 401 error response.

• Navigate the client to GET /fxa-oauth/login?redirect=http://app-endpoint/#. There, a session cookie will be set, and the client will be redirected to a login form on the FxA content server;
• After submitting the credentials on the login page, the client will be redirected to http://app-endpoint/#{token} (the web-app).

The GET /v1/fxa-oauth/params endpoint can be use to get the configuration in order to trade the Firefox Accounts BrowserID with a Bearer Token. See Firefox Account documentation about this behavior
