sslstrip will log passwords and user names but there is a problem with the way that it is installed from the Pineapple bar, if you know how to ssh into the wifi pineapple you can correct the error. to ssh into the pineapple get a program like putty if you are running windows and out of the box it is setup to connect to ssh, type in the ip to the pineapple default being 172.16.42.1 and it will ask you to trust the connection, hit yes and login. once in the shell go ahead and install the package of sslstrip using opkg install -dest usb sslstrip if you have not already installed it. next you want to run two more commands
ln -s /usb/usr/lib/python2.7 /usr/lib/python2.7
and then
touch /usb/usr/lib/python2.7/site-packages/zope/init.py
now you are free to run it in the webgui
this can all be found on the pineapple wiki. sslstrip does not work in most cases against google chrome.
