Keycloak is an open-source identity and access management solution designed to add authentication to applications and secure services with minimal effort. It eliminates the need for developers to handle user storage or authentication processes themselves.

•Single-Sign On: Users authenticate with Keycloak rather than individual applications, facilitating seamless access across multiple applications.
•Identity Brokering and Social Login: Easily enable social network logins and authenticate users with existing OpenID Connect or SAML 2.0 Identity Providers.
•User Federation: Connect to existing LDAP or Active Directory servers, or implement custom providers for other user stores.
•Admin Console: Centrally manage all aspects of the Keycloak server, including user federation, identity brokering, and fine-grained authorization policies.
•Account Management Console: Allow users to manage their profiles, passwords, two-factor authentication, sessions, and account history.
•Standard Protocols: Supports OpenID Connect, OAuth 2.0, and SAML for seamless integration.
•Authorization Services: Beyond role-based authorization, Keycloak provides fine-grained authorization services for detailed policy management.

Keycloak is a Cloud Native Computing Foundation incubation project, continuously evolving to meet modern authentication and authorization needs.

Read more about Authelia

Authelia is an open-source authentication and authorization server and portal designed to provide identity and access management (IAM) for web applications. It offers multi-factor authentication (MFA) and single sign-on (SSO) capabilities, acting as a companion for common reverse proxies to enhance security and user experience.

•Lightweight: With a compressed container size smaller than 20 megabytes and memory usage under 30 megabytes, Authelia is highly efficient.
•Blazing Fast: Written in Go and React, it completes authorization policies and backend tasks in milliseconds, with login portal loading times around 100 milliseconds.
•Efficient: Minimal idle processor usage and low active usage in small business environments.
•Security by Design: Security is a core consideration in Authelia's design process.
•Login Regulation: Prevent brute force attacks by limiting the number of login attempts before locking the user account.
•Password Reset: Users can reset their LDAP or internal passwords via email validation directly from the web interface.
•Single Sign-On: Users only need to log in once to access multiple web applications via session cookies, OpenID Connect 1.0, or Trusted Headers.
•Authorization Policies: Define granular access control policies for users and groups to specific resources or domains.
•Identity Validation: Users without a second-factor device must validate their identity via email, reducing the risk of exploitation.
•Scalability: Designed for high availability, it supports multiple parallel containers on platforms like Kubernetes.
•Multi-Factor Authentication: Supports various second-factor methods, including One Time Passwords, Mobile Push Notifications, and WebAuthn.
•Intuitive User Interface: The login portal is straightforward, offering a transparent workflow for users.

Authelia is a robust solution for enhancing the security and usability of web applications through advanced IAM features.
