How to set focus to an antd Input.Password component?

Question

I am trying to set focus an input.password field. Is it possible?

I didnt see any information on antd docs. I wonder if its possible

Input(Input.TextArea) has a Input(textAreaRef) property through ref. but in Input.Password, I can't find anything about this. Is there a way to accomplish my question?

Password inputs are no different than other text inputs. First you must create a reference to the input, then you can call its focus() method at any point to focus the input. The code below focuses the input when the component mounts:

import React from "react";
import ReactDOM from "react-dom";
import { Icon, Input } from "antd";
import "antd/dist/antd.css";
import "./index.css";

class LoginForm extends React.Component {
  passwordInput = null;

  componentDidMount() {
    this.passwordInput.focus();
  }

  render() {
    return (
      <div className="App">
        <Input
          prefix={<Icon type="lock" style={{ color: "rgba(0,0,0,.25)" }} />}
          type="password"
          placeholder="Password"
          ref={input => {
            this.passwordInput = input;
          }}
        />
      </div>
    );
  }
}

ReactDOM.render(<LoginForm />, document.getElementById("root"));

Sometimes you point with ref to Component instead of DOM-element, so, try this:

In case of Input component from antd library:

import React, { useRef, useEffect } from "react";
import { Input, Form } from "antd";
import "antd/dist/antd.css";

const MyComponent = () => {
  // Same as React.createRef()
  const passwordInput = useRef(null);

  useEffect(() => {
    if (passwordInput.current) {
      // or, if Input component in your ref, then use input property like:
      // passwordInput.current.input.focus();
      passwordInput.current.focus();
    }
  }, [passwordInput]);

  return (
    <Form>
      <Form.Item name="login">
        <Input type="text" placeholder="Login" />
      </Form.Item>
      <Form.Item name="password">
        <Input type="password" placeholder="Password" ref={passwordInput} />
      </Form.Item>
    </Form>
  );
};

export default MyComponent;

In case of DOM Element

import React, { useRef, useEffect } from "react";

const MyComponent2 = () => {
  const passwordInput = useRef(null);

  useEffect(() => {
    if (passwordInput.current) {
      passwordInput.current.focus();
    }
  }, [passwordInput]);

  return (
    <form>
      <input type="text" placeholder="Login" />
      <input type="password" placeholder="Password" ref={passwordInput} />
    </form>
  );
};

export default MyComponent2;

This is example on codesandbox

P.S. useEffect hook works almost same as componentDidMount in Class component
