AspNetCore.Identity.CosmosDb

👁 Build and Test
👁 NuGet

AspNetCore.Identity.CosmosDb is a .NET 10 ASP.NET Core Identity provider backed by Azure Cosmos DB and EF Core Cosmos. It stores users, roles, claims, tokens, external logins, and passkeys in Cosmos DB while preserving the standard ASP.NET Core Identity programming model.

Versioning Note

Package versions now follow SemVer 2.0 for NuGet publishing and no longer mirror the target .NET version number.

This means you may see a larger version jump (for example, from a .NET-aligned version to 12.0.0) without an equivalent framework jump. The target framework and compatibility are still documented separately in this README and in release notes.

Why use this package

• Cosmos DB-backed ASP.NET Core Identity without a relational database
• Standard UserManager<TUser> and RoleManager<TRole> support
• Passkey support for .NET 10 Identity
• Generic key support
• Reusable passkey endpoints and packaged JavaScript client

Install

dotnet add package AspNetCore.Identity.CosmosDb

Basic setup

using AspNetCore.Identity.CosmosDb;
using AspNetCore.Identity.CosmosDb.Extensions;
using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;

var connectionString = builder.Configuration.GetConnectionString("CosmosDb")!;
var databaseName = builder.Configuration["CosmosDb:DatabaseName"]!;

builder.Services.AddDbContext<ApplicationDbContext>(options =>
 options.UseCosmos(connectionString, databaseName));

builder.Services.Configure<IdentityPasskeyOptions>(options =>
{
 options.ServerDomain = builder.Configuration["Passkeys:ServerDomain"]!;
});

builder.Services
 .AddCosmosIdentity<ApplicationDbContext, IdentityUser, IdentityRole, string>()
 .AddDefaultTokenProviders()
 .AddDefaultUI();

Create your context by inheriting from CosmosIdentityDbContext<TUser, TRole, TKey> and call EnsureCreatedAsync() during startup to provision the Cosmos database and required containers.

Passkeys Integration

The package includes passkey persistence plus reusable passkey API endpoints and a packaged JavaScript client.

builder.Services.AddCosmosPasskeyUiIntegration(options =>
{
 options.RoutePrefix = "/identity/passkeys";
 options.ClientScriptPath = "/identity/passkeys/client.js";
});

app.MapCosmosPasskeyUiEndpoints<IdentityUser>();
