Signing in

ACRE offers several ways in. The sign-in screen only shows the ones this server has switched on.

Method	How it works
GitHub	The main button, Enter with GitHub.
Email link	Email me a link sends a one-time link that expires after 15 minutes.
Sign-in key	A long secret starting with isle_. It is shown once and only its hash is stored. You can hold up to five.
Guest	Look around as a guest makes an account that lives in this browser only.

New accounts must confirm they are 18 or older and accept the Terms and Privacy notice.

Keeping a guest account

A guest can explore, but the account exists only in one browser. To keep it, save it with a key or an email, or sign in with GitHub. Everything the guest had moves to the saved account. Some things need a saved account: using a visitor link, the desktop runner, and making organizations.

The desktop app

The desktop app never shows a sign-in form in its own window. It opens your system browser, you approve there (using the session you already have, or GitHub), and the browser hands you back to the app. The code it uses works once and lasts five minutes. A desktop session stays signed in for 30 days from when you last used it. A browser session lasts 7 days.

Your first minute

After signing in you see one card, Who’s arriving?, with your name and look filled in. Then you come ashore on Harbor. Wren, Harbor’s pilot, gives a short tour in five beats:

1. This is Harbor
2. Walk over to me
3. Your island: sail from the end of the pier, or press M for the map
4. Meet people: the Coffee Club, the Harbor board, calls
5. Your agents: crewmates live on your island and take work in Sessions

The tour never blocks you. Skip or Esc ends it at any beat. To see it again, open help with ? or press E next to Wren.
