Open Source Java Identity and Access Management (IAM) Software

Add authentication to applications and secure services with minimum fuss. No need to deal with storing users or authenticating users. It's all available out of the box. You'll even get advanced features such as User Federation, Identity Brokering and Social Login. Keycloak is an open source Identity and Access Management solution aimed at modern applications and services. It makes it easy to secure applications and services with little to no code. Users authenticate with Keycloak rather than individual applications. This means that your applications don't have to deal with login forms, authenticating users, and storing users. Once logged-in to Keycloak, users don't have to login again to access a different application. This also applied to logout. Keycloak provides single-sign out, which means users only have to logout once to be logged-out of all applications that use Keycloak.

The UAA is a multi tenant identity management service, used in Cloud Foundry, but also available as a stand alone OAuth2 server. Its primary role is as an OAuth2 provider, issuing tokens for client applications to use when they act on behalf of Cloud Foundry users. It can also authenticate users with their Cloud Foundry credentials, and can act as an SSO service using those credentials (or others). It has endpoints for managing user accounts and for registering OAuth2 clients, as well as various other management functions.

The Amazon MSK Library for AWS Identity and Access Management enables developers to use AWS Identity and Access Management (IAM) to connect to their Amazon Managed Streaming for Apache Kafka (Amazon MSK) clusters. It allows JVM-based Apache Kafka clients to use AWS IAM for authentication and authorization against Amazon MSK clusters that have AWS IAM enabled as an authentication mechanism. This library provides a new Simple Authentication and Security Layer (SASL) mechanism called AWS_MSK_IAM. This new SASL mechanism can be used by Kafka clients to authenticate against Amazon MSK clusters using AWS IAM. After you've downloaded the code from GitHub, you can build it using Gradle. An uber jar containing the library and all its relocated dependencies except the kafka client and slf4j-api can also be built. At runtime, the uber jar expects to find the kafka client library and the sl4j-api library on the classpath.

WeIdentity is a set of distributed multi-center technical solutions that can carry the credible mapping of the actual identity and chain identity of the entity object (person or thing), as well as the realization of safe access authorization and data exchange between the entity objects. WeIdentity is independently developed and fully open source by the Microbank. It adheres to the concept of public alliance chains integrating resources, exchanging value, and serving the public. It is committed to becoming a distributed commercial infrastructure linking multiple vertical industry fields, promoting pan-industry, cross-institution, and cross-regional. Identity authentication and data cooperation. In the traditional way, user registration and identity management are completely dependent on the single center's registration agency; with the emergence of distributed ledger technology (such as blockchains), distributed multi-center identity registration, and identification.
