-====== User Management ====== +
- +
-User management in Linux is a critical aspect of system administration. It involves creating, modifying, and managing user accounts and groups to ensure proper access control, system security, and resource allocation.

- +

-  * **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. +
- +
-  - //**sudo chage [option] username**// +
- +
-  * **sudo chage -l username** +
-Display the current password aging information +
- +
- +
-{{:screenshot_2025-01-16_162659.png?400|}} +
- +
-  * **sudo chage -E  2025-12-31 username** +
-Set the account expiration date. The account will be disabled after this date. +
-To set account expiration to never use **sudo change -E -1 username** +
- +
- +
-{{:date.png?400|}} +
- +
-  * **sudo chage -W 7 username** +
-The user will receive a warning 7 days before the password expires. +
