+## Custom Table Names
+
+If you want to change the default table names, you can change the table names
+in **app/Config/Auth.php**.
+
+```php
+public array $tables = [
+    'users'             => 'users',
+    'identities'        => 'auth_identities',
+    'logins'            => 'auth_logins',
+    'token_logins'      => 'auth_token_logins',
+    'remember_tokens'   => 'auth_remember_tokens',
+    'groups_users'      => 'auth_groups_users',
+    'permissions_users' => 'auth_permissions_users',
+];
+```
+
+Set the table names that you want in the array values.
+
+> **Note** You must change the table names before running database migrations.
