But it’s a security measure to get it to BFU, where data is at rest and secure, in case your phone is out of your possession for an extended period of time (someone steals it, police take it, etc) so it becomes harder to exploit. I’ve set mine to 12. Some do 4 or even less. Feel free to turn it off.
