+[![CircleCI](https://circleci.com/gh/relekang/django-nopassword.svg?style=svg)](https://circleci.com/gh/relekang/django-nopassword)
+
+_Authentication backend for django that uses a one time code instead of passwords._
+
+This project was originally inspired by [Is it time for password-less login?](http://notes.xoxco.com/post/27999787765/is-it-time-for-password-less-login) by [Ben Brown](http://twitter.com/benbrown)
+
+## Installation
+Run this command to install django-nopassword
+
+    pip install django-nopassword
+
+### Requirements
+Django >= 1.11 (custom user is supported)
+
+## Usage
+Add the app to installed apps
+
+```python
+INSTALLED_APPS = (
+    ...
+    'nopassword',
+    ...
+)
+```
+
+Add the authentication backend *EmailBackend*
+
+```python
+AUTHENTICATION_BACKENDS = (
+    # Needed to login by username in Django admin, regardless of `nopassword`
+    'django.contrib.auth.backends.ModelBackend',
+
+    # Send login codes via email
+    'nopassword.backends.email.EmailBackend',
+)
+```
+
+Add urls to your *urls.py*
+
+```python
+urlpatterns = patterns('',
+    ...
+    url(r'^accounts/', include('nopassword.urls')),
+    ...
+)
+```
+
+### REST API
+
+To use the REST API, *djangorestframework* must be installed
+
+    pip install djangorestframework
+
+Add rest framework to installed apps
+
+```python
+INSTALLED_APPS = (
+    ...
+    'rest_framework',
+    'rest_framework.authtoken',
+    'nopassword',
+    ...
+)
+```
+
+Add *TokenAuthentication* to default authentication classes
+
+```python
+REST_FRAMEWORK = {
+    'DEFAULT_AUTHENTICATION_CLASSES': (
+        'rest_framework.authentication.TokenAuthentication',
+    )
+}
+```
+
+Add urls to your *urls.py*
+
+```python
+urlpatterns = patterns('',
+    ...
+    url(r'^api/accounts/', include('nopassword.rest.urls')),
+    ...
+)
+```
+
+You will have the following endpoints available:
+
+- `/api/accounts/login/` (POST)
+  - username
+  - next (optional, will be returned in `/api/accounts/login/code/` to be handled by the frontend)
+  - Sends a login code to the user
+- `/api/accounts/login/code/` (POST)
+  - code
+  - Returns `key` (authentication token) and `next` (provided by `/api/accounts/login/`)
+- `/api/accounts/logout/` (POST)
+  - Performs logout
+
+### Settings
+Information about the available settings can be found in the [docs](http://django-nopassword.readthedocs.org/en/latest/#settings)
+
+## Tests
+Run with `python setup.py test`.

+Changelog
+=========
+
+5.0.0
+-----
+
+Breaking changes:
+
+- Removed custom length of login codes
+- Do not store the code in the database. Hash and compare on login instead. This might have an performance impact.
+- Add user id to the login code form and urls sent to the user.
+- Changing the secret key will now invalidate all login codes.
+
+4.0.1
+-----
+
+Set the default length of codes to 64. The setting ``NOPASSWORD_CODE_LENGTH`` is considered
+deprecated.
+
+4.0.0
+-----
+
+Added:
+
+- Added ``LoginCodeAdmin``
+- Added rest support
+
+Breaking changes:
+
+- Remove support for Django < 1.11
+- Add support for Django 2
+- ``NoPasswordBackend.authenticate`` doesn't have side effects anymore, it only checks if a login code is valid.
+- ``NoPasswordBackend`` now uses the default django method ``user_can_authenticate`` instead of ``verify_user``.
+- Changed signature of ``NoPasswordBackend.send_login_code`` to ``send_login_code(code, context, **kwargs)``, to support custom template context.
+- ``EmailBackend`` doesn't attach a html message to the email by default. You can provide a template ``registration/login_email.html`` to do so.
+- Removed setting ``NOPASSWORD_LOGIN_EMAIL_SUBJECT`` in favor of template ``registration/login_subject.txt``
+- Renamed form ``AuthenticationForm`` to ``LoginForm``
+- ``LoginForm`` (previously ``AuthenticationForm``) doesn't have side effects anymore while cleaning.
+- ``LoginForm`` (previously ``AuthenticationForm``) doesn't check for cookie support anymore.
+- Removed methods ``get_user`` and ``get_user_id`` from ``LoginForm`` (previously ``AuthenticationForm``).
+- Removed method ``login_url`` and ``send_login_code`` from ``LoginCode`` (previously ``AuthenticationForm``).
+- Renamed template ``registration/login.html`` to ``registration/login_form.html``.
+- Changed content of default templates.
+- Removed views ``login_with_code_and_username``.
+- Refactored views to be class based views and to use forms instead of url parameters.
+- Changed url paths
+- Removed setting ``NOPASSWORD_POST_REDIRECT``, use ``NOPASSWORD_LOGIN_ON_GET`` instead.
+- Removed setting ``NOPASSWORD_NAMESPACE``.
+- Removed setting ``NOPASSWORD_HIDE_USERNAME``.
+- Removed setting ``NOPASSWORD_LOGIN_EMAIL_SUBJECT``.

+
+Welcome to django_nopassword's documentation!
+=============================================
+
+Authentication backend for django that uses a one time code instead of passwords.
+
+Installation
+------------
+Run this command to install django-nopassword::
+
+    pip install django-nopassword
+
+Requirements:
+Django >= 1.11 (custom user is supported)
+
+.. include:: usage.rst
+.. include:: rest.rst
+.. include:: settings.rst

+REST API
+--------
+To use the REST API, *djangorestframework* must be installed::
+
+    pip install djangorestframework
+
+Add rest framework to installed apps::
+
+    INSTALLED_APPS = (
+        ...
+        'rest_framework',
+        'rest_framework.authtoken',
+        'nopassword',
+        ...
+    )
+
+Add *TokenAuthentication* to default authentication classes::
+
+    REST_FRAMEWORK = {
+        'DEFAULT_AUTHENTICATION_CLASSES': (
+            'rest_framework.authentication.TokenAuthentication',
+        )
+    }
+
+Add urls to your *urls.py*::
+
+    urlpatterns = patterns('',
+        ...
+        url(r'^api/accounts/', include('nopassword.rest.urls')),
+        ...
+    )
+
+You will have the following endpoints available:
+
+- `/api/accounts/login/` (POST)
+   - username
+   - next (optional, will be returned in ``/api/accounts/login/code/`` to be handled by the frontend)
+   - Sends a login code to the user
+- `/api/accounts/login/code/` (POST)
+   - code
+   - Returns ``key`` (authentication token) and ``next`` (provided by ``/api/accounts/login/``)
+- `/api/accounts/logout/` (POST)
+   - Performs logout

+Settings
+--------
+
+django-nopassword settings
+++++++++++++++++++++++++++
+
+.. currentmodule:: django.conf.settings
+
+.. attribute:: NOPASSWORD_LOGIN_CODE_TIMEOUT
+
+    Default: ``900``
+
+    Defines how long a login code is valid in seconds.
+
+.. attribute:: NOPASSWORD_HASH_ALGORITHM
+
+    Default: ``'sha256'``
+
+    Set the algorithm for used in logincode generation. Possible values are those who are supported in hashlib. The value should be set as the name of the attribute in hashlib. Example `hashlib.sha256()` would be `NOPASSWORD_HASH_ALGORITHM = 'sha256'.
+
+.. attribute:: NOPASSWORD_LOGIN_ON_GET
+
+    Default: ``False``
+
+    By default, the login code url requires a POST request to authenticate the user. A GET request renders a form that must be submitted by the user to perform authentication. To authenticate directly inside the initial GET request instead, set this to ``True``.
+
+.. attribute:: NOPASSWORD_TWILIO_SID
+
+    Account ID for Twilio.
+
+.. attribute:: NOPASSWORD_TWILIO_AUTH_TOKEN
+
+    Account secret for Twilio
+
+.. attribute:: NOPASSWORD_NUMERIC_CODES
+
+    Default: ``False``
+
+    A boolean flag if set to True, codes will contain numeric characters only (0-9).

+Usage
+-----
+Add the app to installed apps::
+
+    INSTALLED_APPS = (
+        'nopassword',
+    )
+
+Add the authentication backend *EmailBackend*::
+
+    AUTHENTICATION_BACKENDS = (
+        # Needed to login by username in Django admin, regardless of `nopassword`
+        'django.contrib.auth.backends.ModelBackend',
+
+        # Send login codes via email
+        'nopassword.backends.email.EmailBackend',
+    )
+
+Add urls to your *urls.py*::
+
+    urlpatterns = patterns('',
+        url(r'^accounts/', include('nopassword.urls')),
+    )
+
+Backends
+++++++++
+There are several predefined backends. Usage of those backends are listed below.
+
+.. currentmodule:: nopassword.backends.email
+
+.. class:: EmailBackend
+Delivers the code by email. It uses the django send email functionality to send
+the emails.
+
+Override the following templates to customize emails:
+
+- ``registration/login_email.txt`` - Plain text message
+- ``registration/login_email.html`` - HTML message (note that no default html message is attached)
+- ``registration/login_subject.txt`` - Subject
+
+.. currentmodule:: nopassword.backends.sms
+
+.. class:: TwilioBackend
+Delivers the code by sms sent through the twilio service.
+
+Override the following template to customize messages:
+
+- ``registration/login_sms.txt`` - SMS message
+
+
+Custom backends
+~~~~~~~~~~~~~~~
+In backends.py there is a *NoPasswordBackend*, from which it is possible
+to build custom backends. The *EmailBackend* described above inherits from
+this backend. Creating your own backend can be done by creating a subclass
+of *NoPasswordBackend* and implementing *send_login_code*.::
+
+    class CustomBackend(NoPasswordBackend):
+    
+        def send_login_code(self, code, context, **kwargs):
+            """
+            Use code.user to get contact information
+            Use context to render a custom template
+            Use kwargs in case you have a custom view that provides additional configuration
+            """

# django-nopassword
[![CircleCI](https://circleci.com/gh/relekang/django-nopassword.svg?style=svg)](https://circleci.com/gh/relekang/django-nopassword)

_Authentication backend for django that uses a one time code instead of passwords._

This project was originally inspired by [Is it time for password-less login?](http://notes.xoxco.com/post/27999787765/is-it-time-for-password-less-login) by [Ben Brown](http://twitter.com/benbrown)

## Installation
Run this command to install django-nopassword

    pip install django-nopassword

### Requirements
Django >= 1.11 (custom user is supported)

## Usage
Add the app to installed apps

```python
INSTALLED_APPS = (
    ...
    'nopassword',
    ...
)
```

Add the authentication backend *EmailBackend*

```python
AUTHENTICATION_BACKENDS = (
    # Needed to login by username in Django admin, regardless of `nopassword`
    'django.contrib.auth.backends.ModelBackend',

    # Send login codes via email
    'nopassword.backends.email.EmailBackend',
)
```

Add urls to your *urls.py*

```python
urlpatterns = patterns('',
    ...
    url(r'^accounts/', include('nopassword.urls')),
    ...
)
```

### REST API

To use the REST API, *djangorestframework* must be installed

    pip install djangorestframework

Add rest framework to installed apps

```python
INSTALLED_APPS = (
    ...
    'rest_framework',
    'rest_framework.authtoken',
    'nopassword',
    ...
)
```

Add *TokenAuthentication* to default authentication classes

```python
REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.TokenAuthentication',
    )
}
```

Add urls to your *urls.py*

```python
urlpatterns = patterns('',
    ...
    url(r'^api/accounts/', include('nopassword.rest.urls')),
    ...
)
```

You will have the following endpoints available:

- `/api/accounts/login/` (POST)
  - username
  - next (optional, will be returned in `/api/accounts/login/code/` to be handled by the frontend)
  - Sends a login code to the user
- `/api/accounts/login/code/` (POST)
  - code
  - Returns `key` (authentication token) and `next` (provided by `/api/accounts/login/`)
- `/api/accounts/logout/` (POST)
  - Performs logout

### Settings
Information about the available settings can be found in the [docs](http://django-nopassword.readthedocs.org/en/latest/#settings)

## Tests
Run with `python setup.py test`.

Changelog
=========

5.0.0
-----

Breaking changes:

- Removed custom length of login codes
- Do not store the code in the database. Hash and compare on login instead. This might have an performance impact.
- Add user id to the login code form and urls sent to the user.
- Changing the secret key will now invalidate all login codes.

4.0.1
-----

Set the default length of codes to 64. The setting ``NOPASSWORD_CODE_LENGTH`` is considered
deprecated.

4.0.0
-----

Added:

- Added ``LoginCodeAdmin``
- Added rest support

Breaking changes:

- Remove support for Django < 1.11
- Add support for Django 2
- ``NoPasswordBackend.authenticate`` doesn't have side effects anymore, it only checks if a login code is valid.
- ``NoPasswordBackend`` now uses the default django method ``user_can_authenticate`` instead of ``verify_user``.
- Changed signature of ``NoPasswordBackend.send_login_code`` to ``send_login_code(code, context, **kwargs)``, to support custom template context.
- ``EmailBackend`` doesn't attach a html message to the email by default. You can provide a template ``registration/login_email.html`` to do so.
- Removed setting ``NOPASSWORD_LOGIN_EMAIL_SUBJECT`` in favor of template ``registration/login_subject.txt``
- Renamed form ``AuthenticationForm`` to ``LoginForm``
- ``LoginForm`` (previously ``AuthenticationForm``) doesn't have side effects anymore while cleaning.
- ``LoginForm`` (previously ``AuthenticationForm``) doesn't check for cookie support anymore.
- Removed methods ``get_user`` and ``get_user_id`` from ``LoginForm`` (previously ``AuthenticationForm``).
- Removed method ``login_url`` and ``send_login_code`` from ``LoginCode`` (previously ``AuthenticationForm``).
- Renamed template ``registration/login.html`` to ``registration/login_form.html``.
- Changed content of default templates.
- Removed views ``login_with_code_and_username``.
- Refactored views to be class based views and to use forms instead of url parameters.
- Changed url paths
- Removed setting ``NOPASSWORD_POST_REDIRECT``, use ``NOPASSWORD_LOGIN_ON_GET`` instead.
- Removed setting ``NOPASSWORD_NAMESPACE``.
- Removed setting ``NOPASSWORD_HIDE_USERNAME``.
- Removed setting ``NOPASSWORD_LOGIN_EMAIL_SUBJECT``.

Welcome to django_nopassword's documentation!
=============================================

Authentication backend for django that uses a one time code instead of passwords.

Installation
------------
Run this command to install django-nopassword::

    pip install django-nopassword

Requirements:
Django >= 1.11 (custom user is supported)

.. include:: usage.rst
.. include:: rest.rst
.. include:: settings.rst
.. include:: changelog.rst
REST API
--------
To use the REST API, *djangorestframework* must be installed::

    pip install djangorestframework

Add rest framework to installed apps::

    INSTALLED_APPS = (
        ...
        'rest_framework',
        'rest_framework.authtoken',
        'nopassword',
        ...
    )

Add *TokenAuthentication* to default authentication classes::

    REST_FRAMEWORK = {
        'DEFAULT_AUTHENTICATION_CLASSES': (
            'rest_framework.authentication.TokenAuthentication',
        )
    }

Add urls to your *urls.py*::

    urlpatterns = patterns('',
        ...
        url(r'^api/accounts/', include('nopassword.rest.urls')),
        ...
    )

You will have the following endpoints available:

- `/api/accounts/login/` (POST)
   - username
   - next (optional, will be returned in ``/api/accounts/login/code/`` to be handled by the frontend)
   - Sends a login code to the user
- `/api/accounts/login/code/` (POST)
   - code
   - Returns ``key`` (authentication token) and ``next`` (provided by ``/api/accounts/login/``)
- `/api/accounts/logout/` (POST)
   - Performs logout
Settings
--------

django-nopassword settings

.. currentmodule:: django.conf.settings

.. attribute:: NOPASSWORD_LOGIN_CODE_TIMEOUT

    Default: ``900``

    Defines how long a login code is valid in seconds.

.. attribute:: NOPASSWORD_HASH_ALGORITHM

    Default: ``'sha256'``

    Set the algorithm for used in logincode generation. Possible values are those who are supported in hashlib. The value should be set as the name of the attribute in hashlib. Example `hashlib.sha256()` would be `NOPASSWORD_HASH_ALGORITHM = 'sha256'.

.. attribute:: NOPASSWORD_LOGIN_ON_GET

    Default: ``False``

    By default, the login code url requires a POST request to authenticate the user. A GET request renders a form that must be submitted by the user to perform authentication. To authenticate directly inside the initial GET request instead, set this to ``True``.

.. attribute:: NOPASSWORD_TWILIO_SID

    Account ID for Twilio.

.. attribute:: NOPASSWORD_TWILIO_AUTH_TOKEN

    Account secret for Twilio

.. attribute:: NOPASSWORD_NUMERIC_CODES

    Default: ``False``

    A boolean flag if set to True, codes will contain numeric characters only (0-9).

Django settings used in django-nopassword

.. attribute:: DEFAULT_FROM_EMAIL

    Default: ``'root@example.com'``
Usage
-----
Add the app to installed apps::

    INSTALLED_APPS = (
        'nopassword',
    )

Add the authentication backend *EmailBackend*::

    AUTHENTICATION_BACKENDS = (
        # Needed to login by username in Django admin, regardless of `nopassword`
        'django.contrib.auth.backends.ModelBackend',

        # Send login codes via email
        'nopassword.backends.email.EmailBackend',
    )

Add urls to your *urls.py*::

    urlpatterns = patterns('',
        url(r'^accounts/', include('nopassword.urls')),
    )

Backends
There are several predefined backends. Usage of those backends are listed below.

.. currentmodule:: nopassword.backends.email

.. class:: EmailBackend
Delivers the code by email. It uses the django send email functionality to send
the emails.

Override the following templates to customize emails:

- ``registration/login_email.txt`` - Plain text message
- ``registration/login_email.html`` - HTML message (note that no default html message is attached)
- ``registration/login_subject.txt`` - Subject

.. currentmodule:: nopassword.backends.sms

.. class:: TwilioBackend
Delivers the code by sms sent through the twilio service.

Override the following template to customize messages:

- ``registration/login_sms.txt`` - SMS message


Custom backends
~~~~~~~~~~~~~~~
In backends.py there is a *NoPasswordBackend*, from which it is possible
to build custom backends. The *EmailBackend* described above inherits from
this backend. Creating your own backend can be done by creating a subclass
of *NoPasswordBackend* and implementing *send_login_code*.::

    class CustomBackend(NoPasswordBackend):
    
        def send_login_code(self, code, context, **kwargs):
            """
            Use code.user to get contact information
            Use context to render a custom template
            Use kwargs in case you have a custom view that provides additional configuration
