Single Sign On server, OAuth2, Openid Connect, multiple factor authentication with, HOTP/TOTP, FIDO2, TLS Certificates, etc. extensible via plugins

This repository is a production-minded Go backend starter that applies Clean Architecture to keep business logic independent from frameworks, databases, and delivery mechanisms. It organizes code into layers—domain, use cases, interfaces/adapters—so swapping an HTTP framework or database does not ripple through core logic. The template includes well-chosen scaffolding for configuration, logging, dependency injection, error handling, and request validation so teams can focus on business features. It demonstrates practical patterns for repository interfaces, DTOs, and consistent response envelopes that keep APIs predictable. Testing is first-class: ports and adapters are designed for mocking and table-driven tests, which reduces friction when you add features. As a learning resource and a real starter, it helps teams jumpstart services with boundaries that age well.

The GoCloudNative.Bff is an affordable, developer-friendly, and secure Authentication Gateway that can be implemented by anyone. Many BFF solutions or authentication gateways are expensive to purchase, have complicated licenses, and are often very intricate to use. The GoCloudNative.BFF, on the other hand, is a basic, free authentication gateway that you can get up and running quickly.

This is Google's officially supported node.js client library for using OAuth 2.0 authorization and authentication with Google APIs. Use Application Default Credentials when you use a single identity for all users in your application. Especially useful for applications running on Google Cloud. Application Default Credentials also support workload identity federation to access Google Cloud resources from non-Google Cloud platforms. Use JWT when you are using a single identity for all users. Especially useful for server->server or server->API communication. Use workload identity federation to access Google Cloud resources from Amazon Web Services (AWS), Microsoft Azure or any identity provider that supports OpenID Connect (OIDC). Use workforce identity federation to access Google Cloud resources using an external identity provider (IdP) to authenticate and authorize a workforce—a group of users, such as employees, partners, and contractors.

Google2FA is a PHP package that implements two-factor authentication (2FA) using Time-based One-Time Passwords (TOTP) compatible with Google Authenticator and similar apps. It enhances account security by requiring users to enter a time-sensitive code in addition to their password. The library is lightweight, reliable, and easy to integrate into any PHP or Laravel-based authentication flow.

GridAuth is a user credential management system for distributed data and computational grids. GridAuth is configurable and extensible to just about any system requiring credential management, advanced authorization and secure authentication.

GroupsDirectory is a simple module for Python to handle groups and items in a hierarchy. It was developed to provide a flexible user and group management to a web-application. It handles advanced memberships structures which can be used for authorization.

Guardian is a token based authentication library for use with Elixir applications. Guardian remains a functional system. It integrates with Plug but can be used outside of it. If you're implementing a TCP/UDP protocol directly or want to utilize your authentication via channels in Phoenix, Guardian can work for you. The core currency of authentication in Guardian is the token. By default JSON Web Tokens are supported out of the box but you can use any token that Has the concept of a key-value payload, is tamper-proof, can serialize to a String, or that has a supporting module that implements the Guardian.Token behavior. You can use Guardian tokens to authenticate web endpoints (Plug/Phoenix/X), channels/Sockets (Phoenix - optional), and any other system you can imagine. If you can attach an authentication token you can authenticate it.

HTMF is a Java Hard Token Management Framework used to manage the complete livecycle of an organizations Smartcards and/or USB dongles. It communicates with the tokens through a PKCS11 interface.

Eliminate the mundain tasks & ease the use of basic http authentication in php. A lightweight php class that handles http authentication, & user mgmt tasks from flatfile or any SQL compliant db server.

ICRadius is an Open Source RADIUS package utilizing MySQL tables for all dictionaries, user files, accounting data, etc. This allows fast, efficient manipulation and analysis of available data. ICRadius is a mature, production quality RADIUS package.

Set of scripts, part of the official Samba project, able to manage POSIX accounts (users, groups, machines) for SAMBA, stored in a LDAP directory used as a (sort-of) SAM database. Edited by IDEALX in the OpenTrust suite (Cryptonit, IMC, IDX-PKI...)

ISP Candy is a customer and hosting management solution aimed at Internet service and content providers.

IdMUnit is an xUnit automated testing framework for Identity Management solutions.

Identity and service provisioning software component allows service developers to automate the creation, modification and deletion of users' identity and service subscription information on multiple disparate identity stores.

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.

Identityflow provides a framework for building protocol flows that perform distributed Identity operations. Examples of Identity Operations are Single Sign-On (SSO) and Attribute queries.

A web proxy that provides Single Sign-On (SSO) into websites in a manner that protects your passwords and other sensitive information from untrusted network access devices.

InterLDAP is a middleware for identity management, completed with management tools. It is divided in subprojects, all designed for one objective: manage electronic identities, from their creation, trough their life in organization, until their deletion.

Internet Account Replication (IAR) replicates POSIX user credentials between hosts. It is like NIS, but it: * Is really easy to use -- it practically works out of the box; * Works over the Internet -- it is compatible with regular firewalls; and, * Uses SSH to encrypt the data-flow It relies upon GNU nsswitch.conf (in glibc) for integration.
