Joining on Android

Four ways in

• Join with a code on the title screen. Type the code a friend read out, ABCD2345-EFGH6789 for an app-hosted world or a shorter table code for a server you have already added. Spaces, dashes and lower case are fine.
• Scan a QR code. The camera opens (the scanner asks for permission the first time) and a QR from a lobby, a party tab, or a server's own QR button joins or adds it. A code that is not an Open Dungeon Master invite is refused with a message.
• Open a link. An odm:// link opens the app directly. An https://opendungeonmaster.com/j link opens the app once the Play listing's certificate is verified for the link; until then it opens the confirmation page in the browser, which offers the app.
• Add a server from the title screen's menu or the drawer: one field that takes a room code, a server address like play.example.com (https is tried first, then http for a home server), or an invite link.

Signing in

On a world hosted from a friend's app you are asked for a name only; the code is the invitation and the app keeps your seat. On a self-hosted server you sign in or create an account there: username and password, Discord if offered, and an account invite code if the server is invite-only. Invite-only servers accept a live room code as your invitation.

Saved worlds

Every world you join is saved on the home screen and in the drawer with its cover and the host's name. A world hosted from a friend's app is shown offline when their app is closed, with the note that it becomes playable again when the host returns. The hide offline switch trims the list.

A saved world is recognised again by its address, or by its own identity when a tunnel comes back at a new address, and opens with your saved seat rather than being added twice. The app checks a code against the directory before it sends you anywhere, and a link can only move a saved seat to a trusted tunnel address, so a crafted link cannot rebind your seat to a stranger's server.
