drfpasswordless is a quick way to integrate ‘passwordless’ auth into your Django Rest Framework project using a user’s email address or mobile number only (herein referred to as an alias).
Built to work with DRF’s own TokenAuthentication system, it sends the user a 6-digit callback token to a given email address or a mobile number. The user sends it back correctly and they’re given an authentication token (again, provided by Django Rest Framework’s TokenAuthentication system).
Callback tokens by default expire after 15 minutes.
curl -X POST -d “email=aaron@email.com” localhost:8000/auth/email/
Email to aaron@email.com:
...
<h1>Your login token is 815381.</h1>
...
Return Stage
curl -X POST -d "email=aaron@example.com&token=815381" localhost:8000/auth/token/
> HTTP/1.0 200 OK
> {"token":"76be2d9ecfaf5fa4226d722bzdd8a4fff207ed0e”}
Install drfpasswordless
pipenv install drfpasswordless
Add Django Rest Framework’s Token Authentication to your Django Rest Framework project.
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES':
('rest_framework.authentication.TokenAuthentication',
)}
INSTALLED_APPS = [
...
'rest_framework',
'rest_framework.authtoken',
'drfpasswordless',
...
]
And run
python manage.py migrate
EMAIL
and MOBILE
.PASSWORDLESS_AUTH = {
..
'PASSWORDLESS_AUTH_TYPES': ['EMAIL', 'MOBILE'],
..
}
By default drfpasswordless looks for fields named email
or mobile
on the User model. If an alias provided doesn’t belong to any given user,
a new user is created.
3a. If you’re using email
, see the Configuring Email section
below.
3b. If you’re using mobile
, see the Configuring Mobile section
below.
drfpasswordless.urls
to your urls.py from django.urls import path, include
urlpatterns = [
..
path('', include('drfpasswordless.urls')),
..
]
curl -X POST -d "email=aaron@email.com" localhost:8000/auth/email/
// OR
curl -X POST -d "mobile=+15552143912" localhost:8000/auth/mobile/
A 6 digit callback token will be sent to the contact point.
curl -X POST -d "email=aaron@email.com&token=815381" localhost:8000/auth/token/
> HTTP/1.0 200 OK
> {"token":"76be2d9ecfaf5fa4226d722bzdd8a4fff207ed0e”}
Specify the email address you’d like to send the callback token from
with the PASSWORDLESS_EMAIL_NOREPLY_ADDRESS
setting.
PASSWORDLESS_AUTH = {
..
'PASSWORDLESS_AUTH_TYPES': ['EMAIL',],
'PASSWORDLESS_EMAIL_NOREPLY_ADDRESS': 'noreply@example.com',
..
}
You’ll also need to set up an SMTP server to send emails but for
development you can set up a dummy development smtp server to test
emails. Sent emails will print to the console. Read more here. <https://docs.djangoproject.com/en/3.0/topics/email/#console-backend>
__
# Settings.py
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
You’ll need to have the python twilio module installed
pipenv install twilio
and set the TWILIO_ACCOUNT_SID
and TWILIO_AUTH_TOKEN
environment
variables. These are read from os.environ
, so make sure you don't put
them in your settings file accidentally.
You’ll also need to specify the number you send the token from with the
PASSWORDLESS_MOBILE_NOREPLY_NUMBER
setting.
If you’d like to use a custom email template for your email callback token, specify your template name with this setting:
PASSWORDLESS_AUTH = {
...
'PASSWORDLESS_EMAIL_TOKEN_HTML_TEMPLATE_NAME': "mytemplate.html"
}
The template renders a single variable {{ callback_token }}
which is
the 6 digit callback token being sent.
Endpoints can automatically mark themselves as validated when a user logs in with a token sent to a specific endpoint. They can also automatically mark themselves as invalid when a user changes a contact point.
This is off by default but can be turned on with
PASSWORDLESS_USER_MARK_EMAIL_VERIFIED
or
PASSWORDLESS_USER_MARK_MOBILE_VERIFIED
. By default when these are
enabled they look for the User model fields email_verified
or
mobile_verified
.
You can also use auth/verify/email/
or /auth/verify/mobile/
which will
automatically send a token to the endpoint attached to the current
request.user
's email or mobile if available.
You can then send that token to /auth/verify/
which will double-check
that the endpoint belongs to the request.user and mark the alias as verified.
All unrecognized emails and mobile numbers create new accounts by
default. New accounts are automatically set with
set_unusable_password()
but it’s recommended that admins have some
type of password.
This can be turned off with the PASSWORDLESS_REGISTER_NEW_USERS
setting.
Here’s a full list of the configurable defaults.
