file where login passwords is stored

Where is the login password stored in Ubuntu? What is that file? Can I open that file?

Passwords are typically in /etc/shadow. The password is encrypted, so it will not be of much use to you.

What problem are you trying to solve--e.g. did you forget your password?

The same way you open any other file.....it might require root privileges (on Ubuntu, that means use "sudo")

eg--in a terminal:
sudo gedit /etc/shadow
OR
sudo more /etc/shadow

You don't!!---Think about it: If it were possible to decode the passwords then someone could break into the account of every user on the system.

Please answer my question in post #2

You don't.

This is by design, to help protect against (among other things) precisely what you're attempting to do.
