Gumshoe is a Chrome extension for discreet password logging. It monitors the submission of all forms with a password field and stores any unique login details in a local database.
This thing's actually on the Chrome Web Store.
Can you believe it?
UPDATE: Yeah, I don't know why Google let that fly for six years straight. It's finally been removed. Thank heavens!
Anyway, if you are absolutely set on using a tool like this, then you'll have to look into Chrome extensions just a bit. Turn on developer mode, search the Web for info on how to load this into Chrome, and please don't contact me about Gumshoe as I am no longer supporting this project in any capacity at all. 6+ yrs later, goes against everything I stand for...
Once installed, typing gselog anywhere should reveal the log management
page. From here, you can search for records, delete those records, and
change gselog to something more creative.
Provided that the extension is enabled and the user/password pair has not previously been recorded, login attempts to most (semantically correct) websites should be available for review through the log management page (see above).
Aren't keyloggers scary and malicious?
You could call it a keylogger, but 3 out of 4 pedants agree that it logs form submissions, not keystrokes. (It monitors strokes as it listens for the passcode, but they aren't recorded.)
Right, but couldn't you steal my passwords?
No. All data is stored locally using Web SQL; Gumshoe never communicates with another machine.
You're just a bad person all around if you use this to snoop on any person, steal money or property or secrets, etc. I should have removed this widely used extension from the Chrome Store ages before it was removed. Please do not ever contact me about this extension, and just try to be a good person.
