I am looking for a keylogger that can deployed on a login page and save data in desired server / location
P.S: It is only for educational purposes to see how things work.
You can give Custom Fake Portal a try and mess around , basically you just need 3 odd files to make it work
FrontEnd - the actual web page which resembles another page but its yours (fake login screen)
Code Page - the php (mostly) code which will harvest the keys entered into the FrontEnd
Log File - mostly a text file where the typed keys are stored mostly a txt file but some prefer html files aswell for formatting
