So apparently travelers have no legal obligation to provide their passcodes to the officers. Yet,<p>"If a traveller exercises their right to refuse to provide a passcode, their device can be taken from the border and given to the ABF's digital forensic team for examination."<p>So the alternative is not having access to your phone for at least 14 days. Losing access to your phone today is huge.. no 2FA codes means you're probably locked out of many services even on a PC. Not to mention this forensics team has access to software that can break smartphone security.<p>So there is effectively 0 choice. If they want to search your phone, they WILL search it.<p>I guess the only safe way to store private info is online, encrypted and ideally on your own servers.
