How do I change it so my phone doent open to the pin pad?

[Android Central Question]

I have a galaxy s8 and when u I turn it on to the lock screen it brings me to the pin pad or when I get a notification it opens my phone and brings me to the pin pad. I want it to just open to the lock screen, so I have to choose to unlock my phone or not. I used to have it like that but I do know why it changed.
