AuthNet is a package you add to an ASP.NET Core application to get a full login and account management system without building one yourself. Instead of spending weeks writing sign in, password reset, and admin screens from scratch, you install one package and AuthNet gives you working pages for all of it right away. Once installed, it provides ready-made pages for signing in and out, registering, confirming an email address, resetting a password, changing a password, setting up two-factor login codes, updating a profile, and accepting invitations to join the app. It stores this account data in a PostgreSQL or SQL Server database using ASP.NET Core Identity, the standard login system that ASP.NET Core apps already use. For the people who manage the app rather than use it, AuthNet includes admin screens to view and manage users, assign roles and permissions, send invitations, and review a log of administrative actions that were taken. It also supports letting users sign in through an external identity provider using OpenID Connect, and it exposes JSON endpoints so a single-page app's frontend can talk to the same account system. The README is clear that AuthNet is an early release and intentionally leaves some things out for now: it does not yet support JWT-based logins, text-message login codes, passkeys, or serving multiple separate customer accounts from one install. It is licensed under MIT and distributed as NuGet packages, which is how .NET developers normally install libraries into their projects. Setup requires a working ASP.NET Core project, a PostgreSQL or SQL Server database, and basic familiarity with configuring services in Program.cs, so this is aimed at developers already building in that ecosystem rather than complete beginners.
