I have recently rooted my android Smartphone because I wanted to know when I logged into my Facebook account using the Facebook app I saved my login credentials by clicking on save login info. Now I wanted to know where the password/login credentials get saved in which of the android directories & where apps usually store account login information locally on the mobile phone.

Each app stores its data in its own directory, which you will find (if rooted) with a good file manager (e.g. Total Commander) under:

/data/data/<package-name>/

E.g. for Total Commander this would be:

/data/data/com.ghisler.android.TotalCommander

(for Facebook app I don't know).

Mostly the apps store their data in sqlite databases, so you would need an app to read these databases. I used SQLite Editor on my rooted phone, but there are others too. With that you have to search through the tables till you find your data. Most likely the passwords are saved as hashes, not in clear text. You would need rainbow tables to get back to the plain text, with little chances only, depends on the complexity of the password.

Browsers will let you read saved passwords, here you don't even need root but this is likely not what your want to know ;)

So to be short: I don't know where Facebook app saves credentials, I would try to search the Facebook directory with sqlite app.
