How to correctly submit a value via form?

For ajax forms you should use value returned from the hook.

To put value directly to the form use the following approach:

<input value={presentation} onChange={onChange} type="text" />
<input type="hidden" name="form-input-server-name" value={value} />

How to use hook with useForm?

Please see the example:

import React from 'react'
import { Controller, useForm } from 'react-hook-form'
import { useMimicPassword } from 'react-mimic-password-hook'

function App() {
  const [password, passwordPresentation, onChangeMimicPassword] = useMimicPassword()

  const { control, errors, handleSubmit } = useForm({
    defaultValues: {
      password: ''
    }
  })

  const onSubmit = React.useCallback((data) => {
    // Send form...
  }, [])

  return (
    <form noValidate onSubmit={handleSubmit(onSubmit)}>
      <Controller
        control={control}
        name="password"
        rules={{ required: 'Password is required' }}
        render={({ onChange, onBlur, value: _, name }) => (
          <>
            <input
              value={passwordPresentation}
              onChange={(e) => {
                const nextValue = onChangeMimicPassword(e)
                onChange(nextValue)
              }}
              onBlur={onBlur}
            />
            <input type="hidden" value={password} name={name} />
          </>
        )}
      />
      <p style={{ color: 'red' }}>{errors.password?.message}</p>
    </form>
  )
}
