MLflow Access Control (mlflow-oidc-auth)
Authentication and access control for MLflow tracking servers: single sign-on (OIDC, SAML 2.0), SCIM user and group provisioning, service accounts, and per-resource permissions for users, groups and workspaces.
It is an MLflow server plugin, installed as mlflow-oidc-auth and started with --app-name oidc-auth. The package keeps its original name; it has long since grown beyond OIDC.

Features
- Single sign-on for the MLflow UI and API through any OpenID Connect provider (confidential or PKCE public clients) or SAML 2.0 identity provider, with several providers side by side
- Programmatic access: automation authenticates with short-lived workload identities — Kubernetes service-account tokens or IdP client-credentials / workload-identity tokens (JWT bearer); people using the MLflow client from a laptop or notebook use named personal access tokens (basic auth). See Programmatic access
- SCIM 2.0 provisioning of users and groups from your directory
- Permissions (READ, USE, EDIT, MANAGE) on experiments, registered models, prompts, scorers and AI Gateway resources, granted to users, groups or regex patterns, with deny by default
- Workspaces for multi-tenant isolation on a shared MLflow server
- Admin UI for users, groups, service accounts, permissions, workspaces, webhooks and trash
- Operations: server-side sessions, audit log, health probes, Redis-backed permission cache, and secrets from AWS, Azure, HashiCorp Vault or Kubernetes

Quick Start
To get the full version (with entire MLflow and all dependencies), run:
python3 -m venv venv
source venv/bin/activate
python3 -m pip install mlflow-oidc-auth[full]
mlflow server --app-name oidc-auth --host 0.0.0.0 --port 8080
Webhook secret encryption key 🔐
Webhook secrets are stored encrypted in the database using a Fernet key. If you plan to use MLflow webhooks with secrets, set the encryption key in the environment variable MLFLOW_WEBHOOK_SECRET_ENCRYPTION_KEY before creating any webhooks. Generate a key with:
MLFLOW_WEBHOOK_SECRET_ENCRYPTION_KEY=$(python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())")
export MLFLOW_WEBHOOK_SECRET_ENCRYPTION_KEY
Important: keep this key stable across application restarts and replicas. If the key is lost or changed after webhooks are created, previously stored secrets cannot be decrypted and will cause webhook listing to fail until you restore the original key or remove/rotate the affected webhook secrets.
