Client password change api doesn't exist

[Md Lamim Chowdhury]

I'm developing a  WHMCS Custom Client Portal And I'm not found any api for change client password

Hello Lamim!

Welcome to the WHMCS Community!

In WHMCS v8.0+, Clients and Users have been separated:
https://docs.whmcs.com/8-13/clients/users-and-client-accounts/

Previously, you could do that by using the UpdateClient call:
https://developers.whmcs.com/api-reference/updateclient/.

But now, you may be looking to update the User instead, using the UpdateUser call:
https://developers.whmcs.com/api-reference/updateuser/
GetPassword:
https://developers.whmcs.com/api-reference/getclientpassword/
And finally, if needed, ResetPassword call:
https://developers.whmcs.com/api-reference/resetpassword/

If this is available and built in, why was it removed from the admin interface, forcing use of APIs instead, making it more difficult for the admins?

Are you referring to the "Change Password" option on the Users tab?

No, more the clients, since we don't have anyone using "users" to access anything. For us it's one account, one owner, and we used to be able to do this on behalf of clients. 

"Previously, you could do that by using the UpdateClient call"
^^ this, but it was in the admin interface. Client, the account owner, the password fields and options to do something with it directly were removed.
