Anyone know of an Android operating system that will let me use 2 PINs? explanation in post

A while ago I heard of a concept where on your phone lock screen you can put in one pin and get your normal apps etc but put in a different pin and you get a different home screen with everything you want to hide. Don't know if this exists but would be great if it does, this probably isn't the place for this question so if there's a subreddit that fits this question better let me know. Thanks
