i need to call this popup in my custome addons  js file?

out side pos module 

Hi, 

You can create your own customized popup to accept the credentials.

odoo.define('point_of_sale.CreateUserPassPopup', function(require){

    'use strict';

    const AbstractAwaitablePopup = require('point_of_sale.AbstractAwaitablePopup');

    const Registries = require('point_of_sale.Registries');

    const { _lt } = require('@web/core/l10n/translation');


    class CreateSaleOrderPopup extends AbstractAwaitablePopup {

    }

    //Creates a new popup

    CreateUserPassPopup.template = 'CreateUserPassPopup';

    CreateUserPassPopup.defaultProps = {

        confirmText: _lt('Confirm'),

        title: _lt('Enter your username and password'),

        body: '', 	//Here you can customize your body to accept username and password

    };


    Registries.Component.add(CreateUserPassPopup);


    return CreateUserPassPopup;

});

After the completion of creation of the popup you can call it at the desired instance.

this.showPopup('CreateUserPassPopup',{
              title : this.env._t("Your Title"),
              body : this.env._t("Your Body")})

Regards
