Linux User Management: Configuring Password Aging

Systems administrators are responsible for keeping systems secure and safe from hackers. Part of this process is enabling password restrictions, so that users are forced to change their password on a regular basis. In this lab, we will learn to set password restrictions for Linux users. We will set passwords to warn users of required password changes 7 days in advance, require password changes every 30 days, and lock the passwords after 60 days of account inactivity.
