[Windows Central Question]

I can reply without entering pin any message (messenger, viber , whatsapp .. etc ) click on notification on message. How I disable that option. I am using Windows 10 mobile (Lumia 540).

That's strange. See if you have set the duration, for which your phone will not ask for a pin, to something other than "Every time". You can check it under Settings app > Accounts > Sign-in options > Require sign-in. If you set it, for example, to 5 minutes, your phone will not ask you for a pin for 5 minutes once you lock your phone. After 5 minutes elapse, it will ask you for the pin before unlocking. This results in your phone not asking for the pin for replying to those messages till 5 minutes. If you set the duration (mentioned earlier) to "Every time", your phone will ask for the pin before anyone can open apps from the notifications.

Also, setting notifications to be private in the notification settings may help.
