you cold try a mitm attack to capture the data when your connected router

OR
gateway poison
ettercap with gateway poisoning enabled
plus a listener
nc -l -p 8080 -t
would record anything meant to be send to port 8080 on the router so might capture some details that way

OR

 i understand if you know they wifikey you can capure the wifi signal with some air sniffer program on a laptop and decode it with the known password. so it would be like a remote packet capture.
most wificards can at least record in a hacky way.

OR

a live disk like hirens bootdisk to lift/load  the registry hive from the pc you have access to and get a reg editor onto it .

hope this helps S

ssl strip and a mitm is needed mostly for session hijacking
but most sites have different cookies for differnet parts of the site.
example
with yahoo you can capture session data and be 'logged in' on the search page but when you goto the emai section  it askes you for the password.
prpbably because of the 'hacky'nature of session.
but with other more basic sites that use simple logged in or not cookies it is very possable still.
on andoird intercepter-ng  is great at it
set sslstrip run the mitm and wait for a cookie
press the cookie and the site loads with the cookie set and you are logged in as whatever user.
it worked with facebook messenger app but as i said before moveing from once site service to another is a bit dodgy in recent years

i would throw in a vote for https://www.codecademy.com/ as well i am just starting the javascript.

might i add geany is a great ide for php as will as notepad a with your apache.log and error.log open.
