Your question is actually going to require 2 things. The command to change a password remotely for a user:
你的问题实际上需要两件事。为用户远程更改密码的命令：
ssh remoteserver 'echo -e "passwdofuser\npasswdofuser" | passwd username'
In order to do that you probably need to be root, or in the sudo config, have "passwd" NOT require a password for your user to run.
为了做到这一点，您可能需要成为 root，或者在 sudo 配置中，让“passwd”不需要密码才能让您的用户运行。

Edit the file:
编辑文件：
Cmnd_Alias MYPASSWD = /usr/bin/passwd
yourusername ALL = NOPASSWD: MYPASSWD
That should allow you to ssh in and not have to use a password to run the passwd command.
这应该允许您 ssh 进入，而不必使用密码来运行 passwd 命令。
