Johanna Stern interviews a guy who stole more than 300k$ from iPhone users through social engineering. TL;DR: Do not share your passcodes. Do not let people use your iPhone without supervision. I usually do that with 1 big exception: when I hand over my phone to my kids… and their babysitter. I wish iOS could provide a kids mode with an allow list or deny list of apps that are safe to use by anyone. 💻
