FélixIf you think you are entering a situation where your iPhone could be taken from you and used against you, the best thing to do is turn it off, and turn it back on only after you leave that situation. iPhones are the most resistant to physical attacks before you unlock them with your passcode. Lockdown Mode doesn’t make your phone safer against attacks where your adversaries are in possession of your phone (as of iOS 18).
Sloan Studio@fay59 Is a lockout requiring passcode insufficient? With erase on 10 attempts?
@SloanStudio “insufficient” implies a “for my specific goal” and without the specific goal it’s hard to tell, but lockout after first unlock is weaker than rebooting to before first unlock. You still have all of your processes running with whatever contents they might already have loaded in RAM, you might have passwords lying around in plain text in memory, etc. All of that uncertainty is gone if you reboot
