How do you change the lockscreen on an android 6.0

[AC Question]

I bought a new phone that is running Android 6.0 . I wanted to customize my homescreen and lockscreen wallpaper. I did the usual thing, go to settings, display then wallpaper and chose a photo. But it only setted it as homescreen wallpaper. I've tried finding ways to change my lockscreen wallpaper but there isn't any buttons that say 'set as lockscreen' or anything similar. Please help me

Welcome to the forums. What phone do you have? Many models won't let you set a different wallpaper for the lock screen.

While the home screen has a standardized way to change its background, the lock screen has no such standard. Thus, each phone maker or carrier has to create their own way if they are going to allow it. Some third-party apps try to gather up lots of these ways.

Which phone?
Which carrier?
