Is there any way to find out when and how the password was removed from Samsum Galaxy Note 5?

Password was removed from my Note 5 how do I find out when and how that happened?

I don't believe there is any logging for that. Process of elimination:
- when did you last unlock it?
- was the device left unattended since you last unlocked it?
- who could have had access to your device during that period?
