[BNM] single sign on portal / storing password?

[Jason Bailey]

Hello,

I'm possibly mixing a few things up here but does anyone have any useful 
references/tips on creating a (web based) single sign on type thing. How, 
for example, does facebook store my twitter details to allow me to post to 
twitter via facebook. They're somehow storing my password and are able to 
use it to post to the twitter api. Obviously they may be storing my 
password but I suspect they're using some kind of two way encrpytion with 
the encrypted password stored in a DB.

I just wanted to create a little app that did a few things for me and while 
it's fine for a desktop app to store a password on a local machine (well 
not fine) but what if I wanted to store other passwords in a DB.

Jas
