Advanced Social Account Usage

Adapter Customization

The social account adapter allows you to customize core behaviors throughout the authentication flow. Create a custom adapter by subclassing DefaultSocialAccountAdapter.

Creating a Custom Adapter

myapp/adapters.py:

from allauth.socialaccount.adapter import DefaultSocialAccountAdapter

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def is_open_for_signup(self, request, socialaccount):
        """
        Control whether new signups are allowed.
        Return False to disable social signups.
        """
        return True
    
    def new_user(self, request, sociallogin):
        """
        Instantiate a new User instance.
        Override to use a custom user model or set defaults.
        """
        user = super().new_user(request, sociallogin)
        # Set custom defaults
        user.is_active = True
        return user
    
    def save_user(self, request, sociallogin, form=None):
        """
        Save the user instance.
        Override to add custom logic before/after saving.
        """
        user = super().save_user(request, sociallogin, form)
        # Add custom logic
        return user
    
    def populate_user(self, request, sociallogin, data):
        """
        Populate user instance with data from provider.
        
        Args:
            data: Dictionary with common fields (first_name, last_name, 
                  email, username, name)
        """
        user = super().populate_user(request, sociallogin, data)
        
        # Add custom field mapping
        if 'company' in sociallogin.account.extra_data:
            user.company = sociallogin.account.extra_data['company']
        
        return user
    
    def get_connect_redirect_url(self, request, socialaccount):
        """
        Return URL to redirect to after connecting a social account.
        """
        return '/dashboard/accounts/'

settings.py:

SOCIALACCOUNT_ADAPTER = 'myapp.adapters.MySocialAccountAdapter'

User Creation and Population

Restrict signups based on provider, domain, or other criteria:

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def is_open_for_signup(self, request, socialaccount):
        # Only allow signups from Google
        if socialaccount.provider != 'google':
            return False
        
        # Only allow company email domains
        email = socialaccount.account.extra_data.get('email', '')
        if not email.endswith('@company.com'):
            return False
        
        return True

Custom User Field Mapping

Map provider-specific data to user fields:

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def populate_user(self, request, sociallogin, data):
        user = super().populate_user(request, sociallogin, data)
        
        provider = sociallogin.account.provider
        extra_data = sociallogin.account.extra_data
        
        if provider == 'github':
            user.bio = extra_data.get('bio', '')
            user.location = extra_data.get('location', '')
            user.website = extra_data.get('blog', '')
        
        elif provider == 'google':
            user.locale = extra_data.get('locale', 'en')
            user.avatar_url = extra_data.get('picture', '')
        
        elif provider == 'linkedin':
            user.headline = extra_data.get('headline', '')
        
        return user

Auto-Assign Roles Based on Provider

from django.contrib.auth.models import Group

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def save_user(self, request, sociallogin, form=None):
        user = super().save_user(request, sociallogin, form)
        
        # Assign role based on provider
        if sociallogin.account.provider == 'google':
            group = Group.objects.get(name='Google Users')
            user.groups.add(group)
        
        # Assign role based on email domain
        email = user.email
        if email.endswith('@company.com'):
            group = Group.objects.get(name='Staff')
            user.groups.add(group)
        
        return user

Custom Redirects

Provider-Specific Redirects

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def get_connect_redirect_url(self, request, socialaccount):
        """
        Called after successfully connecting a social account.
        """
        if socialaccount.provider == 'github':
            return '/dashboard/github-connected/'
        elif socialaccount.provider == 'google':
            return '/dashboard/google-connected/'
        return '/dashboard/accounts/'

Dynamic Redirects Based on User Type

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def get_login_redirect_url(self, request):
        """
        Called after successful social login.
        """
        user = request.user
        
        # Redirect based on user type
        if user.is_staff:
            return '/admin/dashboard/'
        elif user.groups.filter(name='Premium').exists():
            return '/premium/dashboard/'
        else:
            return '/dashboard/'

Customizing Provider Scopes

Request Additional Scopes

Most providers support custom scopes for accessing additional data:

SOCIALACCOUNT_PROVIDERS = {
    'google': {
        'SCOPE': [
            'profile',
            'email',
            'https://www.googleapis.com/auth/calendar.readonly',
            'https://www.googleapis.com/auth/drive.readonly',
        ],
    },
    'github': {
        'SCOPE': [
            'user',
            'user:email',
            'repo',
            'read:org',
            'gist',
        ],
    },
    'microsoft': {
        'SCOPE': [
            'openid',
            'profile',
            'email',
            'User.Read',
            'Calendars.Read',
            'Mail.Read',
        ],
    },
}

Finding Default Scopes

To find the default scopes for a provider:

Look in allauth/socialaccount/providers/<provider>/provider.py
Find the get_default_scope(self) method

Example for Google:

class GoogleProvider(OAuth2Provider):
    def get_default_scope(self):
        scope = ['profile']
        if app_settings.QUERY_EMAIL:
            scope.append('email')
        return scope

Dynamic Scopes

Request different scopes based on context:

class CustomGoogleProvider(GoogleProvider):
    id = 'google_custom'
    
    def get_scope(self, request):
        scopes = super().get_scope(request)
        
        # Add calendar scope for premium users
        if request.user.is_authenticated and request.user.is_premium:
            scopes.append('https://www.googleapis.com/auth/calendar')
        
        return scopes

Customizing Providers

Subclass an Existing Provider

Create a custom provider variant: myapp/providers/google_custom/provider.py:

from allauth.socialaccount.providers.google.provider import GoogleProvider

class GoogleCustomProvider(GoogleProvider):
    id = 'google_custom'
    name = 'Google Custom'
    
    def get_default_scope(self):
        # No scopes by default
        return []
    
    def extract_common_fields(self, data):
        # Custom field extraction
        fields = super().extract_common_fields(data)
        fields['nickname'] = data.get('name', '')
        return fields

provider_classes = [GoogleCustomProvider]

myapp/providers/google_custom/urls.py:

from allauth.socialaccount.providers.oauth2.urls import default_urlpatterns
from .provider import GoogleCustomProvider

urlpatterns = default_urlpatterns(GoogleCustomProvider)

settings.py:

INSTALLED_APPS = [
    # ...
    'myapp.providers.google_custom',
]

Override Provider URLs

Customize the provider URLs:

from allauth.socialaccount.providers.google.views import (
    GoogleOAuth2Adapter,
    oauth2_login,
    oauth2_callback,
)
from django.urls import path

class CustomGoogleAdapter(GoogleOAuth2Adapter):
    # Custom adapter logic
    pass

urlpatterns = [
    path(
        'google/login/',
        oauth2_login,
        {'adapter_class': CustomGoogleAdapter},
        name='google_login'
    ),
    path(
        'google/login/callback/',
        oauth2_callback,
        {'adapter_class': CustomGoogleAdapter},
        name='google_callback'
    ),
]

Authentication Parameters

OAuth2 Authentication Parameters

Pass additional parameters to the authorization endpoint:

SOCIALACCOUNT_PROVIDERS = {
    'google': {
        'AUTH_PARAMS': {
            'access_type': 'offline',  # Request refresh token
            'prompt': 'consent',       # Force consent screen
            'hd': 'company.com',       # Limit to domain
        },
    },
    'github': {
        'AUTH_PARAMS': {
            'allow_signup': 'false',   # Disable GitHub signups
        },
    },
    'microsoft': {
        'AUTH_PARAMS': {
            'prompt': 'select_account',  # Always show account picker
        },
    },
}

Dynamic Auth Parameters

Set parameters dynamically:

class CustomGoogleProvider(GoogleProvider):
    def get_auth_params(self, request, action):
        params = super().get_auth_params(request, action)
        
        # Force consent for premium features
        if request.GET.get('premium'):
            params['prompt'] = 'consent'
            params['access_type'] = 'offline'
        
        return params

Working with OAuth Tokens

Enable Token Storage

SOCIALACCOUNT_STORE_TOKENS = True

Retrieve Access Tokens

from allauth.socialaccount.models import SocialToken

def get_google_token(user):
    try:
        token = SocialToken.objects.get(
            account__user=user,
            account__provider='google'
        )
        return token.token
    except SocialToken.DoesNotExist:
        return None

Make API Calls

import requests
from allauth.socialaccount.models import SocialToken

def get_github_repos(user):
    token = SocialToken.objects.get(
        account__user=user,
        account__provider='github'
    )
    
    headers = {'Authorization': f'token {token.token}'}
    response = requests.get(
        'https://api.github.com/user/repos',
        headers=headers
    )
    
    return response.json()

Refresh Tokens

from allauth.socialaccount.models import SocialToken, SocialApp
from allauth.socialaccount.providers.oauth2.client import OAuth2Client, OAuth2Error
import requests

def refresh_google_token(user):
    try:
        token = SocialToken.objects.get(
            account__user=user,
            account__provider='google'
        )
        app = token.app
        
        # Request new access token
        response = requests.post(
            'https://oauth2.googleapis.com/token',
            data={
                'client_id': app.client_id,
                'client_secret': app.secret,
                'refresh_token': token.token_secret,
                'grant_type': 'refresh_token',
            }
        )
        
        data = response.json()
        
        # Update stored token
        token.token = data['access_token']
        if 'refresh_token' in data:
            token.token_secret = data['refresh_token']
        token.save()
        
        return token.token
        
    except SocialToken.DoesNotExist:
        return None

Email Verification

Trust Provider Email Verification

Mark emails from specific providers as verified:

SOCIALACCOUNT_PROVIDERS = {
    'google': {
        'VERIFIED_EMAIL': True,  # Trust Google's verification
    },
    'github': {
        'VERIFIED_EMAIL': True,  # Trust GitHub's verification
    },
    'facebook': {
        'VERIFIED_EMAIL': False,  # Don't trust Facebook
    },
}

Custom Email Verification Logic

from allauth.account.models import EmailAddress

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def save_user(self, request, sociallogin, form=None):
        user = super().save_user(request, sociallogin, form)
        
        # Mark email as verified for specific providers
        if sociallogin.account.provider in ['google', 'microsoft']:
            email = user.email
            EmailAddress.objects.filter(
                user=user,
                email=email
            ).update(verified=True)
        
        return user

Signals and Hooks

django-allauth provides signals for hooking into the authentication flow:

Available Signals

from allauth.socialaccount.signals import (
    pre_social_login,
    social_account_added,
    social_account_updated,
    social_account_removed,
)
from django.dispatch import receiver

@receiver(pre_social_login)

    Called before a social login is processed.
    Raise an exception to prevent login.
    """
    # Check if email is blacklisted
    email = sociallogin.account.extra_data.get('email')
    if email and is_blacklisted(email):
        raise ImmediateHttpResponse(
            HttpResponse('Email domain not allowed')
        )

@receiver(social_account_added)
def after_account_connected(sender, request, sociallogin, **kwargs):
    """
    Called after a social account is connected to a user.
    """
    user = sociallogin.user
    provider = sociallogin.account.provider
    
    # Log the connection
    logger.info(f'User {user.id} connected {provider} account')
    
    # Award points for connecting account
    user.points += 10
    user.save()

        user.save()

@receiver(social_account_removed)
def after_account_disconnected(sender, request, socialaccount, **kwargs):

    user = socialaccount.user
    provider = socialaccount.provider
    
    logger.info(f'User {user.id} disconnected {provider} account')

from django.http import HttpResponse
from allauth.exceptions import ImmediateHttpResponse

@receiver(pre_social_login)
def check_user_eligibility(sender, request, sociallogin, **kwargs):
    # Only allow users from specific domain
    email = sociallogin.account.extra_data.get('email', '')
    
    if not email.endswith('@company.com'):
        raise ImmediateHttpResponse(
            HttpResponse('Only company employees can sign in', status=403)
        )
    
    # Check against external API
    if not is_authorized_user(email):
        raise ImmediateHttpResponse(
            HttpResponse('User not authorized', status=403)
        )

Multi-Tenant Support

Using Django Sites Framework

Configure different apps per site:

# Enable sites framework
INSTALLED_APPS = [
    'django.contrib.sites',
    # ...
]

SITE_ID = 1

Create separate SocialApp instances via admin and assign to different sites.

Custom Tenant Logic

class MySocialAccountAdapter(DefaultSocialAccountAdapter):
    def get_app(self, request, provider, client_id=None):
        """
        Return the appropriate app based on request context.
        """
        # Determine tenant from domain
        tenant = get_tenant_from_request(request)
        
        # Get app for this tenant
        from allauth.socialaccount.models import SocialApp
        return SocialApp.objects.get(
            provider=provider,
            settings__tenant=tenant.id
        )

Security Best Practices

Require HTTPS

# settings.py
SECURE_SSL_REDIRECT = True
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True

Limit Email Authentication

# Only enable for trusted providers
SOCIALACCOUNT_PROVIDERS = {
    'google': {
        'EMAIL_AUTHENTICATION': True,
    },
    # Don't enable for less trusted providers
    'facebook': {
        'EMAIL_AUTHENTICATION': False,
    },
}

SOCIALACCOUNT_LOGIN_ON_GET = False  # Default, keep it this way

Enable PKCE for OAuth2

SOCIALACCOUNT_PROVIDERS = {
    'google': {
        'OAUTH_PKCE_ENABLED': True,
    },
    'github': {
        'OAUTH_PKCE_ENABLED': True,
    },
}
