    Isolated by design.Each tenant runs in its own browser profile (Chrome, Brave) or its own session partition (Edge).
  • ✓
    Know who’s signed in.Edge portals show a live signed-in status, so you never open the wrong session blind.
  • ✓
    Built for big lists.Sort A–Z, Z–A or by linked status, and jump straight to a customer with the A–Z rail.

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 product. Microsoft handles every sign-in on its own pages — we never see your credentials.
  • ✓
    No Microsoft tokens on our servers.Sign-in stays inside the browser, encrypted with OS-level protection — DPAPI on Windows, Keychain on macOS.
  • ✓
    Native isolation, not a workaround.Firefox Multi-Account Containers and separate desktop profiles keep every tenant's session fully walled off.
  • ✓
    Minimal data by design.Per tenant we keep a name, a SharePoint prefix, and an optional vault URL. Nothing sensitive to breach, because we never collect it.
  • ✓
    Full audit trail for teams.Every portal access is logged with user, tenant, portal, and time — exportable for compliance.
