Microsoft Entra ID SSO for Mealie

Microsoft Entra ID SSO for Mealie

This guide shows how to configure Mealie with Microsoft Entra ID using OpenID Connect (OIDC).

Important design note

If you use a client secret, register the application as a Web / confidential client. Do not document it as a Single Page Application when the backend is using a client secret.

Why use OIDC with Mealie

Benefits:

  • centralized login
  • optional self-service user creation
  • optional group-based restrictions
  • easier identity lifecycle management

Prerequisites

  • Mealie is deployed and reachable via HTTPS
  • you can edit environment variables or Docker Compose
  • permission to create an app registration in Microsoft Entra ID

Step 1: Create the app registration

  • Platform: Web
  • Redirect URI: use the callback URL expected by your Mealie version and reverse proxy design

Record the Tenant ID, Client ID and Client Secret.

Step 2: Configure OIDC in Mealie

OIDC_AUTH_ENABLED=true
OIDC_SIGNUP_ENABLED=true
OIDC_CONFIGURATION_URL=https://login.microsoftonline.com/<tenant-id>/v2.0/.well-known/openid-configuration
OIDC_CLIENT_ID=<client-id>
OIDC_CLIENT_SECRET=<client-secret>
OIDC_PROVIDER_NAME=Microsoft Entra ID
OIDC_USER_CLAIM=email
OIDC_NAME_CLAIM=name
OIDC_GROUPS_CLAIM=groups

Optional:

  • OIDC_USER_GROUP to allow only one specific group
  • OIDC_ADMIN_GROUP to make selected users admins
  • ALLOW_PASSWORD_LOGIN=false only after testing

Best practices

  • keep the app registration dedicated to Mealie
  • use HTTPS only
  • document the exact callback URL used
  • use group-based filtering if access should be limited
  • disable password login only after OIDC is fully tested

Summary

For Mealie, Microsoft Entra ID integration should be documented as a standard OIDC confidential client pattern when a client secret is used.
