Bonus security on iPhone - if you long-press on any app, you can click "Require Face ID" and it will make thieves need your face again to open bank or sensitive apps. I did this for all my financial apps amd also email so they can't reset passwords. It isna minor inconvenience but would hopefully prevent an unlocked phone from being stolen and having bank accounts emptied.
