From the man page for useradd:

useradd is a low level utility for adding users. On Debian,
administrators should usually use adduser instead.

-p, --password PASSWORD
The encrypted password, as returned by crypt(3). The default is to
disable the password.

Note: This option is not recommended because the password (or
encrypted password) will be visible by users listing the
processes.

You should make sure the password respects the system's password
policy.

You didn't say what distro you're using, and that makes a difference. Do you absolutely have to add the user in a single command? It's not difficult to do it with a script which accepts input.

For fedora/red hat/cent you can use:
useradd -p password username

As mentioned above though it is not good practice to have a users password in the history.
I would probably just useradd then do a passwd.
