I recently installed the dektrium user module (which I think is great!), but despite having manually set 'rememberFor' => 1209600, in the module settings, my users are getting logged out within the hour if they have no activity.
The only thing a Google search for this activity revealed was to set 'enableAutoLogin' => true, and configure sign up to set an auth_key.
I did this in the User model I extended on top of your model. But it didn't help.
Any ideas what could be causing this? I haven't been doing anything to mess with User settings other than this, except to add a User component file extending \yii\web\User so that I could create some simple lookup functions.
