Certificate-based authentication module for Microsoft 365 PowerShell modules. Automates certificate creation, app registration, permission assignment, and provides ready-to-use certificates for all M365 services. Features tenant management with secure storage and selection menus. Requires Microsoft Graph PowerShell modules for Azure AD operations.

Multi-tenant Microsoft Graph plumbing for MSPs: validated tenant fleet config, certificate app-only connection management, fault-isolated per-tenant sweeps with throttling retry, and HTML report rendering.

Per-Identity Validated Org-Toggle. Switch between client Microsoft 365 tenants with one command. Verifies the tenant ID after every connect and tears the session down on mismatch, so a wrong-tenant session never survives to the prompt. Stores identifiers only, never credentials.
