Question

Software to be installed
Password Prompt

Answer 1

To play multimedia files you need to install the codecs. In Ubuntu its as easy as:

sudo apt-get install ubuntu-restricted-extras

Next, it prompts for a password. This password is the same password you used to login into your Ubuntu with.

Answer 2

This password (and most any password on your system) is going to be the same one used to log in. The reason for this is to prevent unauthorized users from installing malicious software on your system.

By prompting you for your login password, the system ensures that only you or people who have your password can install software.
