Your Accounts & Organizations

You sign in to SingleSign once. Behind that one sign-in you can have several mailboxes:

• Your personal mailbox — you@singlesign.com. It's yours: no organization can suspend it, transfer it, or take it away.
• A company mailbox for each organization you belong to — you@yourcompany.com. The organization owns it: its admins give it to you, and they can suspend, transfer, or delete it when you leave.

Each one is a separate mailbox — its own inbox, Screener, tags, settings, storage, calendar, documents, and phone credentials. Nothing from one shows up in another unless you ask for it (see All inboxes below). Company mail never lands in your personal inbox, and your organization's admins never see your personal mail.

Belong to several organizations and you have a company mailbox in each. Start two companies of your own on top of that and you'll have four mailboxes under one SingleSign identity — that's the design.

The account menu

Click your avatar in the top-right corner of SingleSign Mail. The menu opens on the mailbox you're in — your name, a chip that reads "Personal" or the organization's name, and the address. Below it:

• Every other mailbox you're signed in to, each with its chip — click one to switch. The app reloads into that mailbox.
• "Add another account" — sign in with a different SingleSign account in the same browser. Your own organizations don't need this; they're listed automatically.
• "Manage your SingleSign Account" — opens singlesign.com, where your account itself lives.
• "Mail settings" for the mailbox you're in. The Settings page also says which mailbox you're in — "You're in Personal · you@singlesign.com" — so you never have to guess.
• "Sign out" — of this mailbox only. Your other mailboxes stay signed in.
• "Sign out of all accounts" — shown when more than one mailbox is signed in. Every mailbox in this browser signs out, and so does your SingleSign session.

The menu refreshes each time you open it, so a company address an admin has just given you appears without signing in again. You also get a notification under the bell and an email — "You've been given you@yourcompany.com at Acme Inc." — the moment it happens.

All inboxes

With more than one mailbox signed in, "All inboxes" leads the folder list in the sidebar. It's one stream across every mailbox you're signed in to, with a chip on each row naming the mailbox it belongs to, and its badge counts unread mail across all of them.

All inboxes is for reading and triage. Opening a conversation switches you into that mailbox, and Compose from All inboxes first asks which mailbox should write the message — so mail always goes out from the right address.

Signing in with any of your addresses

Every address on your account is a sign-in alias: you can sign in to SingleSign with your original email, your @singlesign.com address, or your company address — for as long as you're a member of that organization.

On singlesign.com, Account → Email lists every address on your account, each with an "Open in SingleSign Mail" button that lands you in the right mailbox. Account → Organizations lists the organizations you belong to, your role in each, pending invitations, and "Start an organization".

Phones and mail apps

Each mailbox is added to your phone separately — it's a separate mailbox, with its own app passwords:

1. Switch to the mailbox in the account menu.
2. Open Settings → Phone & apps and create an app password for it.
3. Add the account on your phone. The username is that mailbox's address — you@singlesign.com for your personal mailbox, you@yourcompany.com for a company one.

Repeat for each mailbox you want on the phone. The full steps are in SingleSign Mail on Your Phone.

When access to a company mailbox ends

If you leave an organization — or are removed — your company mailbox is suspended right away: web, phone, and app passwords all stop working for it. The organization keeps the mailbox (it may transfer it to a colleague or delete it), and nothing else of yours is touched: your personal mailbox and your other organizations carry on exactly as before.

In the account menu the mailbox stays listed as "Acme Inc. — access ended" until you click "Remove", which only takes it off this browser. See Joining an organization for what membership means, and Getting started as a business if you run one.
