How to view passwords and account names in Debian?

To view passwords and account names in a Debian system, you can use the following command:

1. View all user account names:

cat /etc/passwd | cut -d: -f1

This will display the account names of all users in the system.

1. Viewing the password of a specific user (requires root access):

sudo grep 'username' /etc/shadow | cut -d: -f2

Replace ‘username’ in the command above with the username whose password you want to view, this will display the hash value of that user’s password.

Please note that password hash values are stored in encrypted form and cannot be directly converted back to plain text passwords.
