<p>"Error message The username contains an illegal character."</p>
<p>Automatic User Names (auto_username:1.5.0) uses <code>\Drupal::service('password_generator')->generate();</code> to create a temporary username which is saved, before a new one is generated and updated after the fact in hook_user_insert(). This used to be <code>user_password()</code> which was still problematic because that function could be overridden too, and automatically patched to this state by Project Update Bot.</p>
<p>Generate Password (genpass:2.0.1) provides a replacement <code>password_generator</code> service, which uses more possible characters to generate passwords, guaranteeing that at least one of each type of character is included in the password. @see <a href="https://git.drupalcode.org/project/genpass/-/tree/2.0.x/src/GenpassPasswordGenerator.php#L180-191">GenpassPasswordGenerator</a> for default character sets.</p>
<p>Drupal core validates the username before it saves the new account in UserNameConstraintValidator, and by setting the username to a password which is almost guaranteed to have a character in it which trip up that validation, giving the "Error message: The username contains an illegal character."</p>
<p>@see <a href="https://git.drupalcode.org/project/auto_username/-/blob/8.x-1.x/auto_username.module#L35-L41">https://git.drupalcode.org/project/auto_username/-/blob/8.x-1.x/auto_username.module#L35-L41</a></p>
<p><strong>NB:</strong> Automatic User Names (auto_username:1.5.0) <strong>is not compatible</strong> with Drupal 8.7.7 through Drupal 9.1. The password_generator service was only introduced in Drupal 9.1.0. @see <a href="https://www.drupal.org/node/3153113">https://www.drupal.org/node/3153113</a> By using the uuid service, auto_username can be compatible back to Drupal 8.7.7 again (unless there are others changes which are not compatible of course).</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>On a D9/10 site:</p>
<ul>
<li>Install:
<ul>
<li>Automatic User Names (auto_username:1.5.0) </li>
<li>Generate Password (genpass:2.0.1)</li>
</ul>
</li>
<li>Configure auto_username with default settings</li>
<li>Configure genpass with default settings</li>
<li>Attempt to add a user using admin interface, or visitor registration</li>
<li>Submission has a <strong>high probability</strong> of generating a username in the form with an illegal character, but not always.</li>
</ul>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Use uuid service to generate a temporary name that is guaranteed to pass Drupal core's UserNameConstraintValidator. The password_generator service can be replaced or decorated to make more secure passwords, while a UUID is always generated according to RFC 4122.<br>
eg <code>f42fd056-1b53-431c-b09a-210c6b1fb1b0</code></p>

<p>There are no other errors logged.<br>
D10.1 seems to have changed the pwd hash.</p>
<p>Can it be connected with D10.1 and the password compatibilty module.<br>
