Usage: MSG <botname> IDENTIFY #<room> <password>

You can either identify to a bot to gain access to everything that bot has access to or you can identify for a single room the bot controls.

/msg SupportBot identify mypa55
/msg SupportBot identify #conferenceroom roompa55

By setting up two ways to identify, the bot can manage multiple rooms and people can be given only the passwords for the rooms where they are allowed access. People who are thoroughly trusted can be given the bot password.
