+### Auth guards
+
+If your users are using non-default auth guards, you might see all `$history->hasUser()` become `false` even though the history sources were generated by authenticated users.
+
+To fix this, you'll need to enable custom auth guards scanning in config file:
+
+```php
+/*
+|--------------------------------------------------------------
+| Enable auth guards scan
+|--------------------------------------------------------------
+|
+| You only need to enable this if your users are using non-default auth guards.
+| In that case, all tracked user operations will be anonymous.
+|
+| - Set to `true` to use a full scan mode: all auth guards will be checked. However this does not ensure guard priority.
+| - Set to an array to scan only specific auth guards(in the given order). e.g. `['web', 'api', 'admin']`
+|

 ### Known issues
 
 1. When updating a model, if its model label(attributes returned from `getModelLabel`) has been modified, the history message will use its new attributes, which might not be what you expect.
