Hey Platonides,
Basically for the ability to move and use accounts to/in other systems, and
our users mostly prefer to be reminded their passwords, instead of giving
new passwords. I can simply keep them during creation and modification of
accounts of course, but I prefer to make a two way encryption with random
seeds, as we've done with our forums, if it's not already done by someone
else.
You can create an authentication plugin

If you already have a Forum, the best is to use the forum credentials.
