    “chage -d 0 username” requires the user to change his password immediately after logon, which is a quite a nice feature.

    Is there an actual difference between using passwd -x 0 username and chage -E YYYY-MM-DD user?

    Also, in case it helps anyone, you can use date -d ’90 days’ for example, if you need to find the exact date 90 days from now to use with something like chage.

      I have to say that I didn’t know the passwd -x command. With this command and according to the man page, you can set the maximum password lifetime in days, when you specify a date or a number of days since January 1, 1970 with the chage -E command. In one case, it is a number of days from now, in the other case, a date in the future. At the end, you should get the same result.

    echo Y0uRp@$$w0rD | passwd –stdin useraccount
    Seems useful for scripting.
