alt Hacker NewsI think it's enough to shut down you phone. Then it needs a pin, and you're entitled to not give that over, I believe. So you should be safe, apart from some kind of rubber-hose cryptanalysis.

> Then it needs a pin
A compromise to this is that many phones have a "lockdown" mode, where it isn't fully off but refuses to accept biometrics until a code/pattern is used to bring it to a more day-to-day mode.
It's less-secure than being fully off, but it also means if you do need to access your phone you can do so more-quickly.
If you don't give a pin, they can seize your devices (Andrew Tate on his 1st visit to Florida said that he refused to give pin and they seized phone and laptop)
That’s probably why they’ve been pushing the MPC app heavily.
If you’re a U.S. citizen: CBP cannot deny you entry to the United States merely because you refuse to unlock the phone. If you’re a non-citizen seeking admission: refusal is much riskier.
The important wrinkle is that CBP’s published policy expressly guarantees that a person being admitted as a U.S. citizen won’t be denied entry solely because CBP couldn’t inspect the device. It doesn’t give lawful permanent resident (green card holders) that same explicit statement. Instead, it says refusal by a “foreign national” can be considered in an admissibility determination.

There are vendors that sell the technology to adversarially access phone data, the "Before First Unlock" is the safest state a phone can be, but it's not infallible. The safest option is to have a burner or factory-reset phone with nothing on it, even if the hack succeeds.
