Introducing IdentitySuite 3.0

I've been writing a short series on OpenIddict basics while preparing this release — IdentitySuite 3.0 is our biggest visual and customization update yet.

What’s New in IdentitySuite 3.0

IdentitySuite 3.0 is our most visually ambitious release yet. We’ve reimagined how developers and designers customize authentication and account management pages, introducing a modern Theme Builder with new templates, gradient support, image backgrounds, and a centralized image library shared across each client.

1. A Completely Redesigned Theme Builder

The new Theme Builder introduces a more intuitive and powerful way to customize every visual aspect of your authentication and account management pages. With four new templates and dozens of configurable properties, IdentitySuite 3.0 gives you full control over layout, spacing, typography, backgrounds, and branding.

Four New Layout Templates

• Centered Form — Classic layout with the form centered and the logo above.
• Form Left — Form on the right, brand panel on the left.
• Form Right — Form on the left, brand panel on the right.
• Centered Layout — Logo and title above the form, subtitle below.

Each template unlocks different customization options inside the Theme Builder, such as Page Container, Brand Panel, Card Header, and Card Body.

Gradient & Image Backgrounds

Version 3.0 introduces full support for gradient backgrounds and image backgrounds across multiple sections, including Page, Page Container, Brand Panel, and Card Body. This allows you to create visually rich and modern layouts with minimal effort.

Live Preview with Automatic Highlighting

The preview area now includes desktop and mobile emulation, and automatically highlights the section you are editing with a red outline. This makes it easier to understand exactly which part of the page is being modified.

2. New Social Login Providers

IdentitySuite 3.0 expands its authentication capabilities with four new social login providers: GitHub, Apple, LinkedIn, and Instagram. Combined with the existing Google, Facebook, and Microsoft providers, this update offers more flexibility and a smoother onboarding experience for end users.

3. Centralized Image Library

Each client now includes a centralized Image Library used for logos, background images, and brand assets. Images can be uploaded, reused, or removed directly from the Appearance panel or the Email Builder, ensuring consistent branding across all pages and email template.

The Theme Builder integrates seamlessly with the Image Library, allowing you to select logos and background images while customizing the Brand Panel or Page Container.

4. Improved Branding Controls

Brand Title, Brand Subtitle, and Logo Source have been enhanced with new typography, spacing, alignment, and shadow options. Logo rendering now supports object‑fit, position, margin, and custom sizing, giving you complete control over brand presentation.

5. Enhanced Account Management Customization

Account pages now support deeper customization through dedicated sections for Page, Card, Card Header, Card Body, Nav Menu, and Nav Button. Backgrounds, spacing, typography, and hover/selected states can be configured independently for a polished and consistent user experience.

The fastest way to get started is through our example projects repository — ready-to-run sample applications and pre-built client configurations for several common scenarios, so you can have a working setup without writing configuration from scratch:
github.com/spin973/IdentitySuite

IdentitySuite's core identity server — OIDC/OAuth 2.0 flows, user and client management, full configuration — is free with no time limit for deployments up to 1 client and 100 users. Premium features like the Theme Builder shown in this article, along with the Dashboard and Email Template Builder, are available as a full 30-day preview on the Free plan, so you can try them before deciding whether to upgrade. Paid plans start at €349/year, with a 14-day no-questions-asked refund.

Upgrading from 2.x

Upgrading to 3.0 is straightforward: update your NuGet packages (IdentitySuite and IdentitySuite.EntityFrameworkCore) to version 3.0.0, enable Apply migrations in your Database settings, and start your application — the required migrations are applied automatically on startup, no manual database work needed.

Existing client themes remain fully compatible with the new theming system, so no action is required after upgrading. If you'd like to adopt the new Theme Builder defaults on an existing client, you can reset the theme at any time from Configuration → Theme Editor.

If your project overrides IdentitySuite's controller endpoint delegates, note that their signatures have changed in 3.0 — see the migration guide for details.
