How to set default account-expiration date for all new users?

How can I set a default account-expiration-date for all new users?

I know we can do it for every new added user with the --expiredate, but I want that it is default and done for every new user!

like when I use adduser someuser and then I type chage -l someuser I want to find directly that the account expires after one year from the adding-day! ' Many thanks for your help!

You can use option -D to edit the default expiry date from command line:

adduser -D --expiredate=2020-12-22

and to list the new defaults:

adduser -D

Worked in Centos7

From useradd man page:

-e, --expiredate EXPIRE_DATE The date on which the user account will be disabled. The date is specified in the format YYYY-MM-DD. If not specified, useradd will use the default expiry date specified by the EXPIRE variable in /etc/default/useradd, or an empty string (no expiry) by default.

So you should change the EXPIRE variable in the /etc/default/useradd to whatever value you like. The same applies for adduser that uses useradd in the background.
