Authelia is an open‑source authentication and authorization server that provides single sign‑on (SSO) and multi‑factor authentication (MFA) for web applications. It acts as an OpenID Connect provider and integrates with reverse proxies, LDAP, and other identity sources.

Use cases

• Add single sign‑on (SSO) to multiple web applications behind a reverse proxy.
• Enforce multi‑factor authentication (MFA) for internal services and users.
• Integrate LDAP or internal user stores with a unified login portal.
• Provide an OpenID Connect provider for custom applications.
• Apply login rate‑limiting and brute‑force protection policies.
• Secure containerized workloads in Docker or Kubernetes with centralized IAM.

When to choose

• You need a self‑hosted, lightweight IAM solution with SSO and MFA.
• Your infrastructure runs on Linux/Docker/Kubernetes and you prefer Go‑based services.
• You require OpenID Connect compliance and want to integrate with existing reverse proxies.
• You want a free, open‑source alternative to commercial IAM products.

When to avoid

• You prefer a fully managed cloud IAM service with enterprise SLAs.
• You need deep Active Directory integration beyond LDAP.
• You require extensive UI customization or a marketplace of pre‑built connectors.
• Your organization mandates a proprietary authentication platform.
