Is a password confirmation field needed in REST Api?

Question

RESTful API

I'm making a Symphony 4 backend for our frontend. On the front there is a registration page and 2 fields: "password" and "confirm password". Do I need to make fields "password" and "password_confirmation" on the backend and check them? Or will just the "password" field suffice?

Answer 1

data on the client cannot be trusted, it must be validated on the server.
either leave one field at the front, or pass both.
