I would like to know if you can hide the widgets on the iPhone lock screen so that they are visible only after unlocking the smartphone.
Hide widgets (more precisely – to prohibit their use) on the lock screen is possible.
To do this, go to Settings – Touch ID and passcode, and uncheck the Today switch .
So you deny access to widgets without unlocking the iPhone, and the page with them will not even be displayed. If you login via Face ID, Touch ID or password – the page with widgets will be located in the usual place.
Please note that in this section you can disable the control point and the notification center on the locked screen.
