My pin lock disappears in 2 seconds after i turn my phone on!

[AC Question]

Just recently iv been having this issue as iv used the pin lock on my S4 pretty much over a month now. However, now just as i turn my phone back on the pin lock appears for 2 seconds and then it becomes the 'swipe to unlock' screen where the pin lock disappears. So now my phone is literly without any pass!

Have you enabled any Smart Lock options in your security settings?
