List of notable OAuth service providers.
Single sign-on (SSO) is an authentication scheme that allows a user to log in with a single ID to any of several related, yet independent, software systems.
A federated identity in information technology is the means of linking a person's electronic identity and attributes, stored across multiple distinct identity management systems.
OpenID is an open standard and decentralized authentication protocol promoted by the non-profit OpenID Foundation. It allows users to be authenticated by co-operating sites using a third-party identity provider (IDP) service, eliminating the need for webmasters to provide their own ad hoc login systems, and allowing users to log in to multiple unrelated websites without having to have a separate identity and password for each. Users create accounts by selecting an OpenID identity provider, and then use those accounts to sign on to any website that accepts OpenID authentication. Several large organizations either issue or accept OpenIDs on their websites.
Notable issue tracking systems, including bug tracking systems, help desk and service desk issue tracking systems, as well as asset management systems, include the following. The comparison includes client-server application, distributed and hosted systems.
OAuth is an open standard for access delegation, commonly used as a way for internet users to grant websites or applications access to their information on other websites but without giving them the passwords. This mechanism is used by companies such as Amazon, Google, Meta Platforms, Microsoft, and Twitter to permit users to share information about their accounts with third-party applications or websites.
OpenSocial is a public specification that outlines a set of common application programming interfaces (APIs) for web applications. Initially designed for social network applications, it was developed collaboratively by Google, MySpace and other social networks. It has since evolved into a runtime environment that allows third-party components, regardless of their trust level, to operate within an existing web application.
In free and open-source software (FOSS) development communities, a forge is a web-based collaborative software platform for both developing and sharing computer applications.
In computing, SPICE is a remote-display system built for virtual environments which allows users to view a computing "desktop" environment – not only on its computer-server machine, but also from anywhere on the Internet – using a wide variety of machine architectures.
OpenAM is an open-source access management, entitlements and federation server platform. Now it is supported by Open Identity Platform Community.
An identity provider is a system entity that creates, maintains, and manages identity information for principals and also provides authentication services to relying applications within a federation or distributed network.
Security Assertion Markup Language (SAML) is a set of specifications that encompasses the XML-format for security tokens containing assertions to pass information about a user and protocols and profiles to implement authentication and authorization scenarios. This article has a focus on software and services in the category of identity management infrastructure, which enable building Web-SSO solutions using the SAML protocol in an interoperable fashion. Software and services that are only SAML-enabled do not go here.
Social login is a form of single sign-on using existing information from a social networking service such as Facebook, Twitter or Google, to login to a third party website instead of creating a new login account specifically for that website. It is designed to simplify logins for end users as well as provide more reliable demographic information to web developers.
Mozilla Persona was a decentralized authentication system for the web, based on the open BrowserID protocol prototyped by Mozilla and standardized by IETF. It was launched in July 2011, but after failing to achieve traction, Mozilla announced in January 2016 plans to decommission the service by the end of the year.
User-Managed Access (UMA) is an OAuth-based access management protocol standard for party-to-party authorization. Version 1.0 of the standard was approved by the Kantara Initiative on March 23, 2015.
Google APIs are application programming interfaces (APIs) developed by Google which allow communication with Google Services and their integration to other services. Examples of these include Search, Gmail, Translate or Google Maps. Third-party apps can use these APIs to take advantage of or extend the functionality of the existing services.
Accounts & SSO, accounts-sso, or lately gSSO is a single sign-on framework for computers.
SQRL or Secure, Quick, Reliable Login is a draft open standard for secure website login and authentication. The software typically uses a link of the scheme sqrl:// or optionally a QR code, where a user identifies via a pseudonymous zero-knowledge proof rather than providing a user ID and password. This method is thought to be impervious to a brute-force password attack or data breach. It shifts the burden of security away from the party requesting the authentication and closer to the operating-system implementation of what is possible on the hardware, as well as to the user. SQRL was proposed by Steve Gibson of Gibson Research Corporation in October 2013 as a way to simplify the process of authentication without the risk of revelation of information about the transaction to a third party.
Nextcloud is a suite of client-server software for creating and using file hosting services. Nextcloud provides functionality similar to Dropbox, Office 365 or Google Drive when used with integrated office suites Collabora Online or OnlyOffice. It can be hosted in the cloud or on-premises. It is scalable, from home office software based on the low cost Raspberry Pi, all the way through to full sized data centers that support millions of users. Translations in 60 languages exist for web interface and client applications.
HIE of One is a free software project that develops tools for patients to manage their own health records. HIE stands for Health Information Exchange, an electronic network for sharing health information across different organizations, hospitals, providers, and patients. It is one of a growing number of tools for encrypted data exchange within the healthcare sector.
Sign in with Apple is a single sign-on provider operated by Apple Inc., introduced on June 3, 2019, at Apple's 2019 Worldwide Developers Conference (WWDC) in iOS 13.
