Linux: Force Users To Change Their Passwords Upon First Login

다음 로그인시 강제로 암호를 바꾸게 하는 방법

로그인 기간을 만료시켜 다음 로그인시 암호를 변경하도록 하는 명령을 사용하는 방법입니다.

만료 기간을 없애려면 아래처럼 해주면 됩니다.

$ chage -E -1 -I 0 -m 0 -M 99999 계정명

혹은 nerver 키워드로 (SUSE는 never를 인식하지 못하는 경우도 있다고 합니다.)

$ chage -E never -I 0 -m 0 -M 99999 계정명

How can I force my Linux users to change their passwords upon the first login under a CentOS / Debian Linux? How do I make sure user must change password at next logon on Linux server?

You can use any one of the following command to change user passwords upon the first login:

[a] usermod command - Modify various user account properties including user password expiry information.
Where,

[b] chage command - Change user password expiry information

Task: Use chage command to force users to chage their password upon first login

Use the following syntax to force a user to change their password at next logon on a Linux:

# chage -d 0 {user-name}
In this example, force tom to change his passsword at next logon, enter:
# chage -d 0 tom

• -d 0 : Set the number of days since January 1st, 1970 when the password was last changed. The date may also be expressed in the format YYYY-MM-DD. By setting it to zero, you are going to force user to change password upon first login.

Further readings:

• man pages - usermod(8), chage(8)
