hmm, I have loaded the Pier in a clean 3.8 image (and the Pier unix  
security package), and there was no password needed to get the config  
site...... is there any default login ?

I think there is a default login when loading directly from the pier package (that manages to load all depedencies) I dont really remember but I think its login: admin pass: pier not sure at all ;)

anyway, the best is probably to reset the pass by evaluating

WADispatcherEditor initialize

an interface will ask you for a user login and password that you'll use for the page
http://localhost:XXXX/seaside/config

See you
