To implement authentication and authorization in a Blazor WebAssembly app, you can use the built-in Authentication and Authorization API provided by ASP.NET Core. Here are the high-level steps:
- Setup Authentication: Configure authentication services in the
Program.csof your Blazor WebAssembly app. You can use various authentication providers like IdentityServer4, Azure AD, or Firebase Authentication.
- Protect Pages/Components: Use the
[Authorize]attribute to protect your Blazor components or pages. Users will need to be authenticated to access these resources.
@page "/secure" @attribute [Authorize]
- Access User Information: Inject the
AuthenticationStateProviderservice into your component to access user information and determine whether the user is authenticated.
@inject AuthenticationStateProvider AuthenticationStateProvider
- Login/Logout: Implement login and logout functionalities using the
- Test: Ensure to test your implementation with various scenarios to confirm that the authentication and authorization are working as expected.
