Currently, online banking TANs, Google Verification Codes etc. are all visible on the lockscreen unless you chose to hide body for ALL messages (which I dont want).

Please add an option that would mark notification content for new messages as private/sensitive (so its hidden on the lockscreen) for contacts that are not in your phonebook/contact list by using VISIBILITY_PRIVATE with Notification.Builder.setVisibility()

Thanks

This way chit-chat is visible on the lockscreen, but TANs and other security related stuff would be protected.
