Authenticator Pro is a free and open-source two-factor authentication app for Android. It features encrypted backups, icons, categories, a high level of customization, and even a Wear OS app. Unlike some alternative apps, Authenticator Pro gives you control over your data. You can import from other apps and export at any time. Authenticator Pro is a community-backed open-source project which aims to provide privacy and security to users. The source-code is auditable by anyone on GitHub and released under the GPL 3.0 license. The project has no corporate ties or interests but, rather has the purpose of providing a secure and private two-factor authentication solution to the privacy-conscious. Unlike alternative user-hostile applications, Authenticator Pro does not lock-in your data or communicate with distant servers. Everything is safely protected in the app and can be exported at any time.

IdentityServer is a free, open-source OpenID Connect and OAuth 2.0 framework for ASP.NET Core. Founded and maintained by Dominick Baier and Brock Allen, IdentityServer4 incorporates all the protocol implementations and extensibility points needed to integrate token-based authentication, single-sign-on and API access control in your applications. IdentityServer4 is officially certified by the OpenID Foundation and thus spec-compliant and interoperable. It is part of the .NET Foundation and operates under their code of conduct. It is licensed under Apache 2 (an OSI-approved license). Active development happens on the main branch. This always contains the latest version. Each (pre-) release is tagged with the corresponding version. The aspnetcore1 and aspnetcore2 branches contain the latest versions of the older ASP.NET Core based versions.

TodoApp is a reference todo application demonstrating a modern full-stack web architecture. Its front end uses a browser-based WebAssembly application, while the backend exposes REST endpoints through Minimal APIs. An object-relational mapper and SQLite provide persistent data storage, with built-in orchestration tooling coordinating application services and dependencies. Authentication examples include identity management, cookies, bearer tokens, and optional social sign-in providers. A reverse proxy forwards requests between the front-end server and API, while rate limiting and OpenAPI demonstrate additional production-oriented capabilities. Integration tests exercise the REST API, and the backend can also run independently for direct API use. Observability tooling collects logs, metrics, and traces that can be inspected through an integrated dashboard.
