Answer 1

The answer of Ghulam.M. works perfectly, but it doesn't show the correct value once you saved, due to the empty value on addValues. I improved the answer with showing the correct values.

namespace Vendor\Module\Plugin\Block\Adminhtml\User\Edit\Tab;
class Main
{
 /** @var \Magento\Framework\Registry */
 protected $_coreRegistry;
 public function __construct(\Magento\Framework\Registry $registry)
 {
 $this->_coreRegistry = $registry;
 }
 /**
 * Get form HTML
 *
 * @return string
 */
 public function aroundGetFormHtml(
 \Magento\User\Block\User\Edit\Tab\Main $subject,
 \Closure $proceed
 )
 {
 /** @var $model \Magento\User\Model\User */
 $model = $this->_coreRegistry->registry('permissions_user');
 $form = $subject->getForm();
 if (is_object($form)) {
 $fieldset = $form->addFieldset('cus_fieldsetname_code', ['legend' => __('Authorization Code')]);
 $fieldset->addField(
 'custom_column',
 'text',
 [
 'name' => 'custom_column',
 'label' => __('Custom Column'),
 'id' => 'custom_column',
 'title' => __('custom_column'),
 'required' => false,
 'note' => 'Custom column '
 ]
 );
 $form->addValues(
 [
 'custom_column' => $model->getData('custom_column'),
 ]
 );
 $subject->setForm($form);
 }
 return $proceed();
 }
}

I have done somewhat similar to this for this first you have to upgrade the admin_user table using UpgradeSchema

UpgradeSchema.php

<?php
 namespace Vendor\Module\Setup;
 use Magento\Framework\Setup\UpgradeSchemaInterface;
 use Magento\Framework\Setup\SchemaSetupInterface;
 use Magento\Framework\Setup\ModuleContextInterface;
 class UpgradeSchema implements UpgradeSchemaInterface
 {
 public function upgrade(SchemaSetupInterface $setup, ModuleContextInterface $context)
 {
 $setup->startSetup();
 //handle all possible upgrade versions
 $installer = $setup;
 $installer->startSetup();
 $connection = $installer->getConnection();
 if (version_compare($context->getVersion(), '1.0.1') < 0) {
 //code to upgrade to 1.0.1
 if ($connection->tableColumnExists('admin_user', 'custom_column') === false) {
 $connection
 ->addColumn(
 $setup->getTable('admin_user'),
 'custom_column',
 [
 'type' => \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
 'length' => 256,
 'nullable' => true,
 'comment' => 'custom_column'
 ]
 );
 }
 }
 $setup->endSetup();
 }
 } 

adminhtml/di.xml

 <?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <type name="Magento\User\Block\User\Edit\Tab\Main">
 <plugin name="admin_user_field" type="Vendor\Module\Plugin\Block\Adminhtml\User\Edit\Tab\Main" sortOrder="1"/>
 </type>
</config> 

Main.php

 <?php
namespace Vendor\Module\Plugin\Block\Adminhtml\User\Edit\Tab;
 class Main
{
 /**
 * Get form HTML
 *
 * @return string
 */
 public function aroundGetFormHtml(
 \Magento\User\Block\User\Edit\Tab\Main $subject,
 \Closure $proceed
 )
 {
 $form = $subject->getForm();
 if (is_object($form)) {
 $fieldset = $form->addFieldset('cus_fieldsetname_code', ['legend' => __('Authorization Code')]);
 $fieldset->addField(
 'custom_column',
 'text',
 [
 'name' => 'custom_column',
 'label' => __('Custom Column'),
 'id' => 'custom_column',
 'title' => __('custom_column'),
 'required' => false,
 'note' => 'Custom column '
 ]
 );
 $form->addValues(
 [
 'custom_column' => '', 
 ]
 );
 $subject->setForm($form);
 }
 return $proceed();
 }
}

To make the answer of Ghulam.M work with M2.3 declartive schema you can replace the UpgradeSchema file with the new declarative schema file which would look as follows:

<?xml version="1.0"?>
<schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">
 <table name="admin_user">
 <column xsi:type="smallint" name="custom_column" padding="5" unsigned="true" nullable="false" identity="false"
 default="0" comment="custom_column"/>
 </table>
</schema>
