When the hub first sees [TAG]Name it:

1. makes a Synchronet user on your door BBS called Name (TAG) (Synchronet allows 25 characters, so long names are shortened, and a number is added if two players would get the same name);
2. gives that user a random password that only the hub knows;
3. remembers the player's password from their BBS, as a bcrypt hash.

Each session the hub runs mkuser.js with jsexec to make sure the user exists and has the right password. If you delete a hub user in Synchronet, it's simply made again next time, with a fresh start in every game.

Users made by the hub have the comment set by new_user_comment (default “Door Hub player”), so they're easy to find in your user editor. They get your BBS's normal new-user settings, with ANSI and colour turned on.

Member BBSes send a password for each caller (doorhub.js makes a random one per caller). The hub keeps the first one it sees for each name. If a different password arrives later for the same [TAG]Name, the hub refuses it with “Your Door Hub password doesn't match”.

This stops a new caller who takes an old caller's name on a member BBS from playing as them. When a member rebuilds their user base, or a caller's BBS account is recreated, reset the player:

doorhub player reset "[KAL]Heisenberg"

The next password that arrives for that name is kept.

• Up to 30 characters, printable ASCII. Names with [ or ] are refused.
• Names are matched without regard to capitals: [KAL]heisenberg is the same player as [KAL]Heisenberg.
• The game sees the door BBS user name (Heisenberg (KAL)). Many doors also let players choose their own name inside the game.
