Thanks to Drupal's permissions and roles system, it is possible to create pages that will not look the same for each user or visitor. To be able to switch quickly from the admin to any user without entering any password, no need to look any further, Masquerade is your friend. A switch block to place wherever you want, visible only to the administrator, an Unmasquerade link to go back in one click and you're good to go. Identity theft is yours ...
composer require drupal/masquerade
