Classes and interfaces in Angular 9

I am pretty new to Angular and how to use oop in this context. I have used a user interface when register a new user.

 export interface User {
 firstName: string;
 lastName: string;
 email: string;
 password: string;
 }

When I edit that user there needs more fields (role, id etc).

export interface User {
_id: string;
role: string;
firstName: string;
lastName: string;
email: string;
password: string;
date: string;

}

Shall I use two interfaces – one for registering and one for editing or should I use a class with required fields and non-required? What is best practice here? Please advise!

   export interface User {
    id: number;
    name?: string; // optional parameter
  }
