I don't have an iPhone so correct me if I'm remembering correctly but aren't they by default protected by a 4 digit numeric pin? A 4 digit numeric pin that a brute force attack can be used on is effectively no security/a backdoor imo.
- mynameisvlad 11y agoI believe the default on new installs is now 6, but options for a more complex PIN, either numeric or straight up alphanumeric, are available.
- RobJDavey 11y agoThere are escalating time limits on incorrect PIN attempts, which is also enforced in hardware by the Secure Enclave in A7 chips and above. This would mean even breaking a 4-digit pin code without that delay being removed would take a long time. Additionally the device may be set to wipe after 10 incorrect attempts. Attempts | Delay 1-4: none 5: 1 minute 6: 5 minutes 7-8: 15 minutes 9: 1 hour Source: https://www.apple.com/business/docs/iOS_Security_Guide.pdf https://www.apple.com/business/docs/iOS_Security_Guide.pdf
