No, you have to be not stupid and realize they are sneaky little fuckers.
It’s not like most gun safes are just sitting out in the kitchen or living room, especially in a household with kids. So kick them out of your bedroom and close the door while you’re retrieving the firearms so they can’t see the combination.
Also biometric safes are pretty common these days, then you can keep the backup physical key in a safe deposit box at the bank or even with a friend.
