then enable this module:

redirect user after login

 

Create redirect_user_after_login.links.menu.yml file

 

redirect_user_after_login.admin:
  title: 'Login Redirect'
  parent: system.admin_config_system
  route_name: redirect_user_after_login.settings

 

Create redirect_user_after_login.routing.yml file

 

redirect_user_after_login.settings:
  path: '/admin/config/system/login_redirect'
  defaults:
    _form: '\Drupal\redirect_user_after_login\Form\RedirectUserAfterLoginForm'
    _title: 'Set Login Redirection Url'
  requirements:
    _permission: 'access content'

 

Create src/Form/RedirectUserAfterLoginForm.php file

 

<?php

namespace Drupal\redirect_user_after_login\Form;

use Drupal\Core\Form\ConfigFormBase;
use Drupal\Core\Form\FormStateInterface;

class RedirectUserAfterLoginForm extends ConfigFormBase
{

    /**
     * {@inheritdoc}
     */
    public function getFormId()
    {
        return 'redirect_user_after_login_form';
    }

    /**
     * {@inheritdoc}
     */
    public function buildForm(array $form, FormStateInterface $form_state)
    {
        // Form constructor.
        $form = parent::buildForm($form, $form_state);
        // Default settings.
        $config = $this->config('redirect_user_after_login.settings');

        $form['url_after_login'] = array(
            '#type' => 'textfield',
            '#title' => $this->t('Url Redirection'),
            '#required' => TRUE,
            '#default_value' => $config->get('redirect_user_after_login.path'),
            '#description' => $this->t('Add a valid url or &ltfront> for front page'),
        );

        return $form;
    }

    /**
     * {@inheritdoc}
     */
    public function validateForm(array &$form, FormStateInterface $form_state) {
        $path = $form_state->getValue('url_after_login');
        $is_valid = \Drupal::service('path.validator')->isValid($path);
        if ($is_valid == NULL) {
            $form_state->setErrorByName('url_after_login', $this->t('Path not found.'));
        }
    }

    /**
     * {@inheritdoc}
     */
    public function submitForm(array &$form, FormStateInterface $form_state) {
        $config = $this->config('redirect_user_after_login.settings');
        $config->set('redirect_user_after_login.path', $form_state->getValue('url_after_login'));
        $config->save();
        return parent::submitForm($form, $form_state);
    }

    /**
     * Gets the configuration names that will be editable.
     *
     * @return array
     *   An array of configuration object names that are editable if called in
     *   conjunction with the trait's config() method.
     */
    protected function getEditableConfigNames()
    {
        return [
            'redirect_user_after_login.settings',
        ];
    }
}

 

then you can set your login redirection url

Redirect after user login in drupal 8

 

Create redirect_user_after_login.module file

 

To redirect user after  login in drupal 8 & 9, You need to alter the login form and add a submit handler which will take care of the redirection using RedirectResponse.

 

<?php
use Drupal\Core\Form\FormStateInterface;
use Drupal\Core\Url;
use Symfony\Component\HttpFoundation\RedirectResponse;

/**
 * Implements hook_form_alter().
 */
function redirect_user_after_login_form_alter(&$form, FormStateInterface $form_state, $form_id)
{
    switch ($form_id) {
        case 'user_login_form':
            $form['#submit'][] = '_login_page_redirect_user_login_form_submit';
            break;
    }
}

/**
 * Custom submit handler for login form.
 */
function _login_page_redirect_user_login_form_submit($form, FormStateInterface $form_state)
{
    $path = \Drupal::config('redirect_user_after_login.settings')->get('redirect_user_after_login.path');
    if ($path == '<front>') {
        $path = '/';
    }
    $homeResponse = new RedirectResponse(URL::fromUserInput($path)->toString());
    $homeResponse->send();
}
