Recovering access

Please use the following trouble-shooting guide to re-gain access to the user 1 account.

1. Using Drush

Simply use the Drush "user:login" command to generate a one-time-login link by invoking:

drush user-login

 Or use the Drush alias:

drush uli

Alternatively you can also set the module status to disabled.

drush php:eval "\Drupal::configFactory()->getEditable('stop_admin.settings')->set('disabled', FALSE)->save(TRUE);"

In case you still can't login, you can disable the module entirely with the following Drush command:

drush pm-uninstall stop_admin

2. Uninstalling module

If you still have a user account with permissions to administer modules, you can simply go to admin/modules/uninstall and uninstall the Stop Administrator Login module.

3. Disabling module from database

You can also disable the module by altering the system database table.

For Drupal 8

• Manually edit the config table where name = 'core.extension' and remove the module from the data blob which is a serialised array.
• Be aware to decrement the module array length as well (...s:6:"module";a:HERE;{...)
• Truncate the cache_config table.

For Drupal 7

You can manually edit the system database table and set the "status" field to 0.

UPDATE system SET status='0' WHERE name='stop_admin';

4. Updating code

If you are still in a position to deploy code, you can put the line of code that adds the validation hook to the forms in comment like so:

if ($form_id === 'user_login_form' || $form_id === 'user_login_block') {
  //$form['#validate'][] = '_stop_admin_prevent_admin_login';
}

This will allow you to login as an administrator to fix your site. Note that you'll need to revert this line back to its original state. Otherwise you have a "hacked" module on your site.

Follow the same principal as in https://www.drupal.org/docs/8/modules/stop-administrator-login/custom-lo... to disable the logic.
