Summary
Cloud migration involves the process of moving data, applications, and other business elements from an on-premises environment to a cloud-based infrastructure. It is a critical move that can transform an organization’s operations, providing enhanced scalability, flexibility, and cost-efficiency.
In this guide, we’ll delve into the Keycloak vs. Authentik vs. Authelia dilemma faced by many in the context of implementing Single Sign-On (SSO) solutions. We’ll also explore various opinions, recommendations, and challenges encountered while choosing an SSO solution for a self-hosted environment.
Understanding Single Sign-On (SSO)
What is Single Sign-On (SSO)?
Single Sign-On (SSO) is an authentication process that allows users to access multiple applications with a single set of credentials. It eliminates the need for users to remember different passwords for various applications, thereby enhancing user experience and security.
Keycloak, Authentik, and Authelia: An Overview
-
Keycloak: Developed by RedHat, Keycloak is a robust open-source identity and access management solution. It provides comprehensive features but might be considered complex for smaller self-hosted setups.
-
Authentik: Offering a user-friendly interface, Authentik is another open-source SSO solution that adapts well to various authentication methods. However, some users have reported challenges in integrating it with specific applications.
-
Authelia: A lightweight open-source alternative, Authelia is praised for its simplicity but criticized for its limited support and smaller community.
Evaluating User Experiences and Recommendations
Several users in the self-hosting community have shared their experiences and preferences regarding these SSO solutions:
Positive Feedback on Authentik
-
Some users praise Authentik for its comprehensive guides and integrations, making it a preferable choice due to its adaptability to various authentication methods.
-
It’s highlighted that Authentik excels in handling different authentication methods like LDAP and SSO.

Challenges with Keycloak and Authelia
-
While Keycloak boasts excellent documentation and support due to its backing by RedHat, it’s deemed overly complex for smaller setups.
-
Authelia receives praise for its simplicity but is critiqued for having a smaller support community and facing challenges in user revocation.
Making an Informed Decision
The decision-making process revolves around assessing the compatibility of these SSO solutions with specific self-hosted applications, such as Dashy, Jellyfin, and Transmission, among others.
Integrating Dashy with Authentik
A user mentions successfully integrating Dashy with Authentik using OAuth2/OpenID, resolving the limitation of Dashy’s support for only Keycloak.
# Code snippet for integrating Dashy with Authentik
import authentik
dashy = authentik.connect("Dashy")
dashy.integrate("Authentik")
The successful integration enables leveraging Authentik’s capabilities despite Dashy’s initial limitations.
Future Prospects and Considerations
While the community provides insights into preferred SSO solutions, it’s essential to consider factors like security audits, ease of setup, and ongoing maintenance.
Security Audits and Solution Maturity
-
Authentik appears promising but lacks a security audit, potentially raising concerns about vulnerabilities.
-
Despite its complexity, Keycloak benefits from regular security audits due to RedHat’s backing, ensuring a certain level of reliability.
Conclusion
Choosing the right SSO solution among Keycloak, Authentik, and Authelia involves a careful assessment of features, community support, ease of integration, and security considerations. Depending on the specific self-hosted applications and organizational requirements, each solution may offer unique advantages and challenges.
