drfpasswordless 1.1.2

Passwordless auth for Django Rest Framework Token Authentication.

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.

Example Usage:

curl -X POST -d “” localhost:8000/auth/email/

Email to

<h1>Your login token is 815381.</h1>

Return Stage

curl -X POST -d "token=815381" localhost:8000/callback/auth/

> HTTP/1.0 200 OK
> {"token":"76be2d9ecfaf5fa4226d722bzdd8a4fff207ed0e”}


- Python (2.7, 3.4, 3.5, 3.6+)
- Django (1.8, 1.9, 1.10, 1.11+)
- Django Rest Framework + AuthToken (3.4, 3.5, 3.6+)
- Python-Twilio (Optional, for mobile.)


  1. Install drfpasswordless

    pip install drfpasswordless
  2. Add Django Rest Framework’s Token Authentication to your Django Rest Framework project.

        // …

    And run migrate.

  3. Set which types of contact points are allowed for auth in your The available options are EMAIL and 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 Email section below.

  4. Add drfpasswordless.urls to your

    urlpatterns = [
        url(r'^', include('drfpasswordless.urls')),
  5. You can now POST to either of the endpoints:

    curl -X POST -d "" localhost:8000/auth/email/
    curl -X POST -d "mobile=+15552143912" localhost:8000/mobile/

    A 6 digit callback token will be sent to the contact point.

  6. The client has 15 minutes to use the 6 digit callback token correctly. If successful, they get an authorization token in exchange which the client can then use with Django Rest Framework’s TokenAuthentication scheme.

    curl -X POST -d "token=815381" localhost:8000/callback/auth/
    > HTTP/1.0 200 OK
    > {"token":"76be2d9ecfaf5fa4226d722bzdd8a4fff207ed0e”}

Configuring Emails

Specify the email address you’d like to send the callback token from with the PASSWORDLESS_EMAIL_NOREPLY_ADDRESS setting.

You’ll also need to set up an SMTP server to send emails (See Django Docs), 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.

EMAIL_HOST = 'localhost'

Then run the following:

python -m smtpd -n -c DebuggingServer localhost:1025

Configuring Mobile

You’ll need to have the python twilio module installed

pip install twilio

and set the TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN environment variables.

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:


The template renders a single variable {{ callback_token }} which is the 6 digit callback token being sent.

Contact Point Validation

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 /validate/email/ or /validate/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 /callback/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.
