Drupal 8.x

I have inherited several Drupal 8 sites that are in version 8.6.3. No updates of any kind have been done since the sites were built. So no updates have been done in over 2 years.

The sites were originally done as Drupal 6 sites and then were migrated up to Drupal 8.6.3. The db is full of legacy tables that were carried over, no big deal except this bloats the db making it impossible to work on in the server and in docker where I cannot set the max_vars_input in the php settings. 

I am now working on this on a local MAMP pro environment.

I've created a list of users (customers) with some account details, but they don't have passwords set.

I want to send them a 'generate password' link that will prompt them to set their own password for activating their account.

What is the most suitable module for this in 8.x? 

Thanks in advance! :)

I have this code:

I have a large organization that will be utilizing the same site install configuration for hundreds of sites.  We are using Drupal 8 with Media Library integrated into CKEditor and would like to have a folder of organization images (like logos) available on each site.  We currently use BitBucket to manage our repositories of sites, working off one main repository and forking that for each individual site.  

Needs:
- Must allow for images in folders or as a separate media type
- Must be able to add via file structure and not via manual upload

In my node type template, how do I display alternate text if comments are closed for the node ?

{% if content.comment %}
<div class="card mb-5 p-3 shadow">
{{ content.comment }}
</div>
{% else %}
<div class="card mb-5 p-3 shadow">
{{ content.field_link }}
{{ content.field_code }}
</div>
{% endif %}

Hello friends!

I'm looking to move to a different CMS, and I need a solution that can manage multiple sites with a master page or site exists, from which sub-sites/pages inherit content updates.

Is this something Drupal can do?
