2FAS Auth Browser Extension
Source code for 2FAS Auth Browser Extension
2FAS Auth Browser Extension is a cross-browser plugin that integrates the 2FAS multi-factor authentication platform directly into the user’s web browsing workflow, helping streamline login flows by interfacing with web pages and 2FA token generation in a seamless way. Once installed in browsers like Chrome, Firefox, or others that support standard extension APIs, it can detect 2FA prompts on login forms and offer to fill or suggest one-time passwords generated by your 2FAS mobile clients or local vault, reducing friction and manual copy-paste steps. The extension communicates securely with companion mobile or desktop clients to fetch or synchronize token data, respecting encryption and privacy boundaries so that secrets are never exposed to the extension itself without user consent. It also lets users manage or view registered accounts, add new ones by scanning QR codes via companion apps, and handle token organization from within browser UI elements. -

AWS Jupyter Proxy
Jupyter server extension to proxy requests with AWS SigV4 authentican
A Jupyter server extension to proxy requests with AWS SigV4 authentication. This server extension enables the usage of the AWS JavaScript/TypeScript SDK to write Jupyter frontend extensions without having to export AWS credentials to the browser. A single /awsproxy endpoint is added on the Jupyter server which receives incoming requests from the browser, uses the credentials on the server to add SigV4 authentication to the request, and then proxies the request to the actual AWS service endpoint. All requests are proxied back-and-forth as-is, e.g., a 4xx status code from the AWS service will be relayed back as-is to the browser. Using this requries no additional dependencies in the client-side code. Just use the regular AWS JavaScript/TypeScript SDK methods and add any dummy credentials and change the endpoint to the /awsproxy endpoint. -

Identity & Single Sign On for all earthlings and beyond
Welcome to the home of the Apereo Central Authentication Service project, more commonly referred to as CAS. CAS is an enterprise multilingual single sign-on solution and identity provider for the web and attempts to be a comprehensive platform for your authentication and authorization needs. CAS is an open and well-documented authentication protocol. The primary implementation of the protocol is an open-source Java server component by the same name hosted here, with support for a plethora of additional authentication protocols and features. Monitor and track application and system behavior, statistics and metrics in real-time. Manage and review audits and logs centrally, and publish data to a variety of downstream systems. Manage and register client applications and services with specific authentication policies. Cross-platform client support (Java, .NET, PHP, Perl, Apache, etc). -

Comeonin
Password hashing specification for the Elixir programming language
Comeonin is the long-standing password-security library for Elixir that standardizes secure hashing and verification practices in Phoenix and Plug applications. It provides a uniform interface for modern algorithms such as Argon2, Bcrypt, and PBKDF2 (implemented in companion packages), along with guidance for salts, cost factors, and timing-safe comparisons. The library’s helpers make it straightforward to add registration and login flows that resist brute-force and side-channel attacks. Migration paths and checks are included so you can upgrade algorithms or work factors over time without breaking existing credentials. Its focus on practical ergonomics—clear APIs, sensible defaults, and good docs—has made it the de facto choice for password handling in Elixir. By centralizing hashing concerns, Comeonin helps teams avoid subtle security mistakes while keeping authentication code terse and testable. -

PHP OAuth 2.0 Server
A spec compliant, secure by default
league/oauth2-server is a standards compliant implementation of an OAuth 2.0 authorization server written in PHP which makes working with OAuth 2.0 trivial. You can easily configure an OAuth 2.0 server to protect your API with access tokens, or allow clients to request new access tokens and refresh them. The latest version of this package supports PHP 7.2, PHP 7.3, PHP 7.4, PHP 8.0. The openssl and json extensions are also required. All HTTP messages passed to the server should be PSR-7 compliant. This ensures interoperability with other packages and frameworks. The library uses PHPUnit for unit tests. We use Github Actions, Scrutinizer, and StyleCI for continuous integration. In order to prevent man-in-the-middle attacks, the authorization server MUST require the use of TLS with server authentication as defined by RFC2818 for any request sent to the authorization and token endpoints. The client MUST validate the authorization server’s TLS certificate as defined by RFC6125. -

Passport
Simple, unobtrusive authentication for Node.js
Passport is a flexible authentication middleware for Node.js that provides a modular and extensible system for handling user login and identity in web applications. It doesn’t impose specific user model structures or storage strategies but instead offers a unified API driven by “strategies”—small plugins that encapsulate authentication logic for protocols such as local username/password, OAuth, OpenID, SAML, and many others. This design allows developers to plug in only the strategies they need and swap or add new ones without rewriting core application logic, making Passport highly adaptable for diverse authentication requirements. Passport hooks into Express (and similar frameworks) using middleware functions that run during the request lifecycle, simplifying tasks like session management, credential validation, and user serialization. -

passport-facebook
Facebook authentication strategy for Passport and Node.js.
passport-facebook is a Passport strategy for authenticating users with their Facebook credentials using the OAuth 2.0 protocol, enabling Node.js applications to let visitors log in with their Facebook account easily. It manages the redirection to Facebook’s login page, the authorization code exchange, and the retrieval of basic profile information, reducing the boilerplate developers would otherwise write to integrate with Facebook’s API manually. When used with Express and Passport, the strategy triggers redirects and callback handling automatically based on configured routes, so developers can focus on application logic like user onboarding and account linkage. The module normalizes the returned user profile into a consistent format so you can store or use profile data with minimal translation. It also handles secure token exchange and sanitization of inputs to protect against common OAuth attacks. -
