Package: drfpasswordless
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-XPOST-d“email=aaron@email.com”localhost:8000/auth/email/Email toaaron@email.com:...
<h1>Your login token is 815381.</h1>
...Return Stagecurl-XPOST-d"email=aaron@example.com&token=815381"localhost:8000/auth/token/

Framework project.REST_FRAMEWORK={'DEFAULT_AUTHENTICATION_CLASSES':('rest_framework.authentication.TokenAuthentication',)}INSTALLED_APPS=[...'rest_framework','rest_framework.authtoken','drfpasswordless',...]And runpythonmanage.pymigrateSet which types of contact points are allowed for auth in your
Settings.py. The available options areEMAILandMOBILE.PASSWORDLESS_AUTH={..'PASSWORDLESS_AUTH_TYPES':['EMAIL','MOBILE'],..}By default drfpasswordless looks for fields namedemailormobileon the User model. If an alias provided doesn’t belong to any given user,
a new user is created.3a. If you’re usingemail, see the Configuring Email section
below.3b. If you’re usingmobile, see the Configuring Mobile section
below.Adddrfpasswordless.urlsto your urls.pyfromdjango.urlsimportpath,includeurlpatterns=[..path('',include('drfpasswordless.urls')),..]You can now POST to either of the endpoints:curl-XPOST-d"email=aaron@email.com"localhost:8000/auth/email/

//OR

curl-XPOST-d"mobile=+15552143912"localhost:8000/auth/mobile/A 6 digit callback token will be sent to the contact point.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-XPOST-d"email=aaron@email.com&token=815381"localhost:8000/auth/token/

with thePASSWORDLESS_EMAIL_NOREPLY_ADDRESSsetting.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.pyEMAIL_BACKEND='django.core.mail.backends.console.EmailBackend'Configuring MobileYou’ll need to have the python twilio module installedpipenvinstalltwilioand set theTWILIO_ACCOUNT_SIDandTWILIO_AUTH_TOKENenvironment
variables. These are read fromos.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 thePASSWORDLESS_MOBILE_NOREPLY_NUMBERsetting.TemplatesIf 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.Contact Point ValidationEndpoints 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 withPASSWORDLESS_USER_MARK_EMAIL_VERIFIEDorPASSWORDLESS_USER_MARK_MOBILE_VERIFIED. By default when these are
enabled they look for the User model fieldsemail_verifiedormobile_verified.You can also useauth/verify/email/or/auth/verify/mobile/which will
automatically send a token to the endpoint attached to the currentrequest.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.RegistrationAll unrecognized emails and mobile numbers create new accounts by
default. New accounts are automatically set withset_unusable_password()but it’s recommended that admins have some
type of password.This can be turned off with thePASSWORDLESS_REGISTER_NEW_USERSsetting.Other SettingsHere’s a full list of the configurable defaults.DEFAULTS={# Allowed auth types, can be EMAIL, MOBILE, or both.'PASSWORDLESS_AUTH_TYPES':['EMAIL'],# URL Prefix for Authentication Endpoints'PASSWORDLESS_AUTH_PREFIX':'auth/',#  URL Prefix for Verification Endpoints'PASSWORDLESS_VERIFY_PREFIX':'auth/verify/',# Amount of time that tokens last, in seconds'PASSWORDLESS_TOKEN_EXPIRE_TIME':15*60,# The user's email field name'PASSWORDLESS_USER_EMAIL_FIELD_NAME':'email',# The user's mobile field name'PASSWORDLESS_USER_MOBILE_FIELD_NAME':'mobile',# Marks itself as verified the first time a user completes auth via token.# Automatically unmarks itself if email is changed.'PASSWORDLESS_USER_MARK_EMAIL_VERIFIED':False,'PASSWORDLESS_USER_EMAIL_VERIFIED_FIELD_NAME':'email_verified',# Marks itself as verified the first time a user completes auth via token.# Automatically unmarks itself if mobile number is changed.'PASSWORDLESS_USER_MARK_MOBILE_VERIFIED':False,'PASSWORDLESS_USER_MOBILE_VERIFIED_FIELD_NAME':'mobile_verified',# The email the callback token is sent from'PASSWORDLESS_EMAIL_NOREPLY_ADDRESS':None,# The email subject'PASSWORDLESS_EMAIL_SUBJECT':"Your Login Token",# A plaintext email message overridden by the html message.
