-  * **Manage password aging and expiration** +
- +
-The ''sudo chage'' command is used in Linux to manage password aging and expiration policies for a user. It allows administrators to define and control how long a user's password remains valid, enforce password expiration, and specify warnings before password expiration. +
- +
-The syntax is: ''sudo chage [option] username'' +
- +
-1. Displays the current password aging information. +
-  sudo chage -l username +
- +

-  sudo chage -E  2025-12-31 username +
- +
-{{:date.png?nolink&600|}} +
- +
-The account will be disabled after this 2025-12-31. To set account expiration to **never:** +
-  sudo change -E -1 username +
- +
-3. Set a warning to the user 7 days before the password expires. +
