How to recover oftc Debian irc password

Ok, it’s terrible! I also didn’t remember my OFTC IRC password. OFTC works the same way as Freenode, but it currently hosts Debian IRC channels.

The procedure is a little different from Freenode, only when sending private messages to nickserv and it will send a temporary password: <em><strong>/msg nickserv help</strong></em> P.S.: Thanks OFTC Staff for the tip.
