I am not a security expert, but my understanding is that the main problems for the FBI are: a) There is a timed delay for trying new passwords after enough unsuccessful attempts and b) The phone will wipe itself after 10 unsuccessful attempts.<p>It&#x27;s pretty much only sufficient to have (a) since the delays will make it take years to guess the password by brute force.<p>I just ctrl-f&#x27;d for &quot;delay&quot; in the security guidelines[0], which claim that the secure enclave is the one that enforces the timed delay[1], so I guess the only attack vector would be if you could somehow backdoor code onto the chip. I can&#x27;t find anything in the guide from a quick skim, but I&#x27;d suspect the code is on a ROM chip or is somehow prevented from an upgrade without an unlock?<p>[0] <a href="https:&#x2F;&#x2F;www.apple.com&#x2F;business&#x2F;docs&#x2F;iOS_Security_Guide.pdf" rel="nofollow">https:&#x2F;&#x2F;www.apple.com&#x2F;business&#x2F;docs&#x2F;iOS_Security_Guide.pdf</a>
