Firefox Extension · Desktop App · Multi-Account Containers

Every client tenant.
One click. Zero mix-ups.

Stop signing out to sign in. Tenant Launcher opens each customer's M365 admin centers in a fully isolated session — separate logins, side by side.

Firefox: Native container isolation — no separate add-on needed.  ·  Chrome/Edge/Brave: Desktop app coming soon — same account, same tenants.

How it works

Stop logging in and out. Manage every client from one place.

Set up each tenant once. From then on, one click puts you inside the right admin portal, already signed in, with no risk of touching the wrong client's account.

1

Add your clients, sign in once

Type a company name — that's the whole setup. The extension creates an isolated container for that client and opens their Microsoft 365 Admin. Sign in once and stay signed in, permanently.

2

Launch any portal in one click

Microsoft 365, Exchange, Entra, SharePoint — pick a client, pick a portal, you're in. Every session is completely isolated so you can never accidentally make changes in the wrong tenant.

3

Session expired? Your vault is one click away

Link each client to their password record in IT Glue or any vault. When a session times out, a quick-access button appears right on the Microsoft sign-in page — no hunting required.

Security

We built this to hold as little as possible.

  • ✓
    No passwords, ever.There's no password field anywhere in the extension or desktop app. Microsoft handles every sign-in, on Microsoft's own pages — we never see your credentials.
  • ✓
    No Microsoft tokens touch our servers.Sign-in happens entirely inside a real browser tab or isolated profile, bound to that tenant. Tokens are encrypted by the browser using OS-level protection — DPAPI on Windows, Keychain on macOS.
  • ✓
    Built on native isolation, not a workaround.Firefox uses native Multi-Account Containers. The desktop app gives each tenant a fully separate browser instance — sessions can't bleed between customers.
  • ✓
    Minimal data by design.Per tenant we store exactly: a name, a SharePoint domain prefix, and an optional vault URL. No customer credentials, no customer data — there's nothing sensitive to breach because we never collect it.
  • ✓
    Full audit trail for Enterprise teams.Every portal access is logged with user, tenant, portal type, and timestamp — searchable and exportable for compliance.
