I have a user with an Android Enterprise Samsung device that seemly has his passcode or pattern changed everyday.

Of course this leads him to call our IT department and we have to Reset Passcode for him to get into the phone. He is the only user out of 300 with the same phone and profiles that is having this issue.

I'm fairly certain its him who is changing the passcode (could be for different reasons). I'd like to know if its possible to track the passcode change OR to lockdown the passcode and so a user can't change it to something else.
