Introduction

The best modern answer depends on which "OpenID" you actually mean. For new Django projects, the right default is usually OpenID Connect, not legacy OpenID 2.0. If your provider supports OpenID Connect, use a package built for OIDC and treat old OpenID-only integrations as legacy exceptions.

Start by Separating OpenID 2.0 from OpenID Connect

These names are easy to blur together, but they lead to different recommendations.

• OpenID 2.0 is the older decentralized login protocol.
• OpenID Connect is the modern identity layer built on OAuth 2.0.

For most current providers, OpenID Connect is the practical choice because it has active ecosystem support, better interoperability with modern identity platforms, and healthier Django package options.

So if you are starting a new integration, the best solution is usually:

• prefer OpenID Connect
• choose a maintained Django package for your provider model

Good Modern Package Choices

If you are integrating a single enterprise identity provider or a small number of OIDC providers, mozilla-django-oidc is a focused option.

If you want broader social-account support and a more provider-oriented ecosystem, django-allauth is often the better fit. It supports OpenID Connect providers and still has a legacy OpenID provider for the rare cases where you truly need old OpenID 2.0.

For many application teams, django-allauth is the most flexible answer because it can cover:

• local accounts
• social login
• multiple identity providers
• OpenID Connect configuration in one auth stack

Example: OpenID Connect with django-allauth

A minimal OpenID Connect provider configuration in settings looks like this:

1INSTALLED_APPS = [
2    "django.contrib.sites",
3    "allauth",
4    "allauth.account",
5    "allauth.socialaccount",
6    "allauth.socialaccount.providers.openid_connect",
7]
8
9SITE_ID = 1
10
11SOCIALACCOUNT_PROVIDERS = {
12    "openid_connect": {
13        "APPS": [
14            {
15                "provider_id": "my-idp",
16                "name": "My Identity Provider",
17                "client_id": "your-client-id",
18                "secret": "your-client-secret",
19                "settings": {
20                    "server_url": "https://id.example.com/.well-known/openid-configuration",
21                },
22            }
23        ]
24    }
25}

That points the Django app at the provider’s discovery endpoint and lets the package handle the protocol details.

When Legacy OpenID 2.0 Still Matters

Sometimes the provider really is old OpenID 2.0. Steam is a common example. In that case, a package with explicit legacy OpenID support, such as django-allauth, is more realistic than trying to force an OIDC-only library into the job.

The key is to treat that as an exception path, not the default architectural answer for new authentication work.

If you are building your own authentication server or choosing a new provider, do not start with OpenID 2.0 in 2026.

How to Choose Between the Main Options

Choose mozilla-django-oidc when:

• you only need OpenID Connect
• the provider is enterprise-focused
• you want a narrower integration surface

Choose django-allauth when:

• you need multiple providers
• you want social auth alongside local accounts
• you may need both OIDC and a few legacy auth paths

The right answer is less about which package is universally "best" and more about which one matches your provider mix and account model.

Common Pitfalls

The biggest pitfall is asking for "OpenID" and then implementing the wrong protocol generation. Before choosing a package, confirm whether the provider is OpenID 2.0 or OpenID Connect.

Another mistake is selecting a legacy OpenID-only library for a provider that already supports OIDC. That usually leaves you with more complexity and less long-term support.

Developers also sometimes underestimate configuration details such as callback URLs, discovery endpoints, and session settings. Authentication packages remove protocol plumbing, but they do not remove the need for careful environment configuration.

Finally, if you handle multiple providers, do not build a custom auth framework unless you truly need one. A maintained Django package is usually the safer path.

Summary

• For new Django projects, prefer OpenID Connect over legacy OpenID 2.0.
• 'django-allauth is a strong general-purpose choice when you need provider flexibility.'
• 'mozilla-django-oidc is a good focused choice for OIDC-only integrations.'
• Use legacy OpenID support only when the provider genuinely requires it.
• Confirm the protocol first, then choose the package that matches your provider model.
