Pattern vs PIN vs Face ID for vault apps
Face ID is convenient on the phone, but a vault should use a secret separate from the device unlock when your threat knows the iPhone passcode. Blopman offers PIN or pattern for that separate secret.
Shoulder surfing
Long patterns can be watched; PINs can be filmed. Cup the screen. Change secrets if exposed.
Shared device passcode
If someone knows the iPhone passcode, biometrics tied to that passcode are not a second factor for Photos Hidden. A vault PIN/pattern still helps.
Blopman choice
Pick PIN or pattern—whichever you enter accurately under stress—and keep the recovery phrase on paper.
