How to Check Unix Password?

Checking Unix passwords is a fundamental task in maintaining cybersecurity for Unix-based systems. Here is a step-by-step guide to help you check Unix passwords:

1. Open a terminal window on your Unix system.
2. Use the command passwd -S username to check the status of a specific user's password. This will show you whether the password is locked, expired, or set to never expire.
3. To examine the password policy settings, use the command grep username /etc/shadow. This command will display detailed information about the password, such as its expiration date and minimum password age.
4. For a more user-friendly view of the password policy settings, you can also use the command chage -l username.

By following these steps, you can effectively check Unix passwords and ensure the security of your system.
