Do you see an error in the client’s js console?
Here are the errors that prosody 0.11 appears to generate

Hi Damencho,
i have tried both options:
-
Installed prosody 0.11, set
muc_room_default_persistent=true
I set a password, left the call and je-joined. Prosody will crash. -
for the second option i think i also need prosody 0.11. In prosody 0.10 i do not find where the event
muc-room-pre-createist fired. I have no lua knowledge, but syntax is not accepted
local pass = http.query.for.password for this event.room;
modulemanager error Unable to load module 'muc_room_pre_crea
te/mod_muc_room_pre_create': ...ules/mod_muc_room_pre_create/mod_muc_room_pre_cr
eate.lua:3: <name> expected near 'for'

I think there just needs to be more documentation on the different use cases for authentication.
It’s weird that the Jitsi Devs are using a set up they wont document publicly.
The ‘secure domain’ set up is very specific. A more common set up is groups who may be given admin or user access to particular rooms. Why no set up for this documented is strange.
Hopefully we can one out soon.

Hello Damencho,
can you tell about were to configure the hook for muc-room-pre-create? I enabled to module at the Component “conference.***” “muc” but couln’t succeed. As far I can see the additional module is called by the hook but afterwards the password is reset to nil in password.lib.lua (the same hook).
Kind regards,
Martin
Hi,
I was looking for a solution to a similar problem and could not get this done using persistent rooms nor with the muc-room-pre-create hook. However, using the muc-room-created hook seems to work.
Here is what I came up with (sorry if thats horrible code, first time that I use Lua):
local store = module:open_store("persistent_muc_passwds", "map");
if not store then
module:log("error","Failed to open storage.");
return nil;
end
module:hook("muc-room-destroyed", function (event)
local room = event.room;
local password = room:get_password(room);
if password then
module:log("debug", "Room %s with pass %s about to be destroyed", room, password);
if not store then
module:log("debug","failed to open store on destroy");
return nil;
end
local now = os.time();
store:set(room.jid, "last_used", now);
store:set(room.jid, "password" , password);
module:log("debug", "Stored %s, %s for room %s", password, now, room);
elseif store:get(room.jid, "password") then
-- moderator removed old password from restored room, delete stored entry
store:set(room.jid, "last_used", nil);
store:set(room.jid, "password" , nil);
module:log("debug", "Deleted stored entries for room %s", room);
end
return nil; -- can be removed
end, 0);
module:hook("muc-room-created", function (event)
local room = event.room;
module:log("debug","hooked room create for %s", room);
local old_pass = store:get(room.jid, "password");
if not old_pass then
module:log("debug", "No password to restore for room %s", room);
return nil;
end
module:log("debug", "Loaded old password '%s' for room %s", old_pass, room);
local last_used = store:get(room.jid, "last_used");
if not last_used then
module:log("debug", "No stored timestamp found for room %s. Removing stored entry.", room, err);
store:set(room.jid, "last_used", nil);
store:set(room.jid, "password" , nil);
return nil;
end
if is_room_stale(last_used) then
-- delete entry
store:set(room.jid, "last_used", nil);
store:set(room.jid, "password" , nil);
module:log("debug", "deleted password for stale room %s", room);
return nil;
end
-- restore old pass for the mucroom
local success = room:set_password(old_pass);
if not success then
module:log("warn", "Failed to set old password %s for restored room %s.", old_pass, room);
end
module:log("debug", "Set password '%s' for restored room %s.", old_pass, room);
return nil;
end, 0);
function is_room_stale(last_used)
local days = module:get_option_number("days_to_persist_muc_passwds", 30);
module:log("debug", "Function is_stale() called with '%s', days is set to %s", last_used, days);
local daysfrom = os.difftime(os.time(), last_used) / (24 * 60 * 60);
local roomage = math.floor(daysfrom) ;
module:log("debug", "roomage is %s days", roomage);
if roomage then
return roomage > days;
end
return false;
end
Save this as mod_persist_muc_passwords.lua in the modules directory and add the module to the muc’s list of enabled modules. You should also change the storage for this module to something persistent (instead of “memory”). My muc config looks like this:
Component "muc.meet.jitsi" "muc"
--storage = "internal";
default_storage = "memory";
storage = {
persistent_muc_passwds = "internal";
}
days_to_persist_muc_passwds = 7;
modules_enabled = {
"persist_muc_passwords";
}
Tested with Prosody Version: 0.11.2-1~bpo9+1 in the docker-jitsi-meet setup.
I am aware of several problems with this approach:
- passwords are stored in plaintext
- whoever restores the old room will be moderator and can change or remove the password
-
does not work with authentication/securedomainEDIT: apparently this works also with authentication, my config was wrong when I tested this.
Maybe somebody who has more experience with prosody, jitsi and the Lua language can help to improve this module in this regards…

Hi plotka,
tnx very much, this is what i looked for!
Here i have Ubuntu 19.10 / prosody 0.11.2-1
Your solution is working here together with authentification (secure domain).
Passwords are stored in files like /var/lib/prosody/conference%2emeet%2eexample%2eorg/persistent_muc_passwds/confname%40conference%2emeet%2eexample%2eorg.dat

Hi!
Cannot get the snippet working, the ‘success’ is always nil. Please could you help out?

That method never returns in prosody 0.9 https://github.com/bjc/prosody/blob/0.9.14/plugins/muc/muc.lib.lua#L296
While in 0.11 it returns https://github.com/bjc/prosody/blob/0.11/plugins/muc/password.lib.lua#L16

@damencho Thanks, Damian!
module:hook("muc-room-created", function (event)
local room = event.room;
module:log("debug", "hooked room create for %s", tostring(room));
local pass = tostring(randPW(8));
local res = room:set_password(pass);
module:log("info", "Set password '%s' for %s.", pass, tostring(room));
return res;
end, 0);
However the hook is constantly repeated, the password is not set and in the logs I can see multiple set password events.
Please could you give a hint on what Im doing wrong?
Thanks, very much appreciated.
I believe I had some trouble when returning anything else but nil, so your return res; statement could be a problem. However, as mentioned before, I do not really know Lua, nor the prosody API.
Still the same…

@damencho Damian, maybe you can help?
Did you try the muc-room-pre-create hook? Did not work for me on prosody 0.11 because jicofo failed to join the room but this may be different when using prosody 0.9.
Well, you need to let jicofo in the room, as jicofo is the first one to join normally.
Well, you need to let jicofo in the room, as jicofo is the first one to join normally.
Yes, thats why I switched to using the muc-room-created hook, to set the password only after jicofo joined.
@osys Another idea: have you tried to lower the priority of your hook to some negative value instead of 0?
Merging my discussion into this as I’m now in the same situation.

Using the muc_room_default_persistent = true method I now have a different error: connection.GET_SESSION_ID_ERROR
I just closed the browser and joined in a private tab.
Folks, I’ve finally made it working by updating to the freshest version of Prosody

You can try to adjust the module posted above to fit your needs, that is do not allow to delete the password and don’t let rooms go stale (perhaps just remove the muc-room-destroyed hook.
Restart prosody to enable the module.
Now create a room, set a password and leave the room. Check that a plaintext file has been created in prosody’s data folder in a folder called <your-muc-component>/persistent_muc_passwords/<urlencoded_muc_name>.dat
Then also enable the prosody module described here: https://modules.prosody.im/mod_muc_config_restrict.html and add the muc#roomconfig_roomsecret option. Restart prosody again. For each room you want to setup, create a file similar to the file you checked in the last step. Make sure these are only readable by the prosody user.
This is still just a workaround, as anybody who joins a room first (i.e. the moderator) will see the Remove Password button. However, clicking this button shows an error message stating that passwords were not supported.
Hope this helps!

I am using docker as well and would to have this setup. Is it possible for you to layout in a more detailed guide? I am struggling on where the modules locations are and if we need to turn that on in the docker-compose.yml file (via .env).
