Tenant Launcher Poseidon Tech מאת

MSP Tenant Launcher is a productivity tool for managed service providers (MSPs) who manage Microsoft 365 tenants for multiple clients.

Instead of logging in and out of Microsoft admin portals for each customer, MSP Tenant Launcher opens each client's portal in its own isolated Firefox container — keeping sessions completely separate so you can never accidentally make changes in the wrong tenant.

FEATURES
- One-click access to Microsoft 365 Admin, Exchange Admin, Entra Admin, and SharePoint Admin for each client
- Each client gets its own isolated container — sessions never bleed between tenants
- Sign in once per client and stay signed in
- Optional password vault link per tenant — when a session expires, a quick-access button appears directly on the Microsoft sign-in page
- Add, edit, search, and delete tenants from the Manage Tenants page
- Export your tenant list to share with colleagues — import on any machine
- Requires a free account at tenantlauncher.com

PRIVACY & SECURITY
- No passwords, credentials, or Microsoft tokens are ever stored by this extension
- Only tenant names, SharePoint domain prefixes, and optional vault link URLs are saved locally
- Container mappings are stored in browser.storage.local — never transmitted anywhere
- All Microsoft authentication happens directly on Microsoft's own pages

PLANS
- Free: up to 3 tenants
- Starter (~$6/mo): up to 20 tenants
- Unlimited (~$10.99/mo): no tenant limit
- Enterprise: team plans with multiple seats

Firefox only — relies on Firefox Multi-Account Containers, which is native to Firefox and not available in Chromium-based browsers.
