It's called Android Smart Lock and has been a thing since Android 5 (Lollipop). It also works (worked? Does it still exist) with 'trusted places' (GPS/WiFi), Voice/Face (before face id was a thing) and a mode were it kept the phone unlocked as long as you kept it on your body.
I remember that I used the last option many years ago, as that was really convenient and worked very well. Basically as long as the phone was in your hand or pocket it kept unlocked, but as soon as you laid it on a table it got locked.
But now that fingerprint unlock is a thing, I don't even mind unlocking my phone as it is one fluid motion and happens unconsciously.
