Umbraco Auth Provider
This helps you add OAuth and SSO login buttons to the Umbraco backoffice. You still need to configure the C# authentication provider backend yourself, but this generates the frontend presentation layer: the login button UI, auto-redirect behavior, popup settings, and account linking options. It pulls from official Umbraco docs and handles both the simple case (default button with icon and label) and custom elements when you need branded UI. Most useful when you're wiring up Google, Microsoft, GitHub, or enterprise SSO and need the backoffice login screen to actually show the button. Saves you from hunting through extension registry docs.

Umbraco Auth Provider
What is it?
An Auth Provider enables external login (OAuth/SSO) for the Umbraco backoffice. It provides the UI component (login button) that connects to a backend authentication provider. The backend must be configured separately in C# - this extension type handles the frontend presentation and behavior. Common providers include Google, Microsoft, GitHub, and custom OAuth providers.
Documentation
Always fetch the latest docs before implementing:
- External Login Providers: https://docs.umbraco.com/umbraco-cms/run-in-production/security/external-login-providers
- Extension Types: https://docs.umbraco.com/umbraco-cms/extend-your-project/backoffice-extensions/extending-overview/extension-types
- Foundation: https://docs.umbraco.com/umbraco-cms/extend-your-project/backoffice-extensions/foundation
Workflow
- Fetch docs - Use WebFetch on the URLs above
- Ask questions - Which OAuth provider? Custom UI needed? Auto-redirect?
- Configure backend - Set up C# authentication provider first
- Generate frontend files - Create manifest + optional custom element
