<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>This is not urgent, but something to deal with eventually. The <a href="https://www.drupal.org/project/friendlycaptcha">friendlycaptcha</a> module is required by the <code>drupal_cms_anti_spam</code> recipe. It is a privacy-friendly and effective solution as it doesn't require any remote server to verify the form submission. All works locally.</p>
<p>The issue <span class="drupalorg-gitlab-issue-link project-issue-status-info project-issue-status-7"><a href="https://www.drupal.org/project/friendlycaptcha/issues/3482109" title="Status: Closed (fixed)">#3482109: Support FriendlyCaptcha V2</a></span> highlights, that the current 1.x branch is no longer maintained, and the new 2.x branch will no longer support the local-only approach.</p>

<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>There is an alternative solution which has that local-only option as their go-to-default right from day 1. It is a very solid implementation and works as expected. Therefore, let's switch over from friendlycaptcha to <a href="https://www.drupal.org/project/altcha">ALTCHA</a>.</p>
<p>We may not require an upgrade path for this, as it will only affect new installations. So, the switch should be straightforward.</p>
