Yup. For the unaware, your phone is likely encrypted at startup, and uses your PIN/password as a key. So if you turn it off, they’ll have a hell of a time breaking into it.
At the very least, initiate an emergency mode. On iOS, this can be done by holding the lock and volume down buttons for a few seconds. It will show the “Emergency Dial” option, along with the power down option and the medical ID option. Once you have seen that screen, the phone is locked until the PIN is used. It disables all biometrics, so they can’t just use your face or thumb print to unlock it. And this makes it significantly harder for them to access your phone.
Yeah, but then don't kill it with a fucking 4 digit PIN or pattern. Use a good password. Yes, it takes longer to type it in, but it would take far longer to brute-force.
This is also an important note for airports. I always fully power off my phone before going through security and/or border control (when flying out of YVR they're one and the same). The last time you'll be asked for your bordering pass is when queueing for security, so you can turn it off (assuming you've got a digital boarding pass) after that point and only power it back on when you arrive at your gate.
For the truly paranoid use a paper boarding pass - no airlines or airports that I've ever been to require digital passes, there are people without phones or phone plans that still must be allowed to board planes. I'm curious if Singapore or the UAE might only allow digital passes because they've leaned hard into digitization - but nearly all the world still has some user path for paper boarding passes.
If you can’t turn off your iPhone, squeeze the volume up button and power button at the same time. This puts the phone in before first unlock mode and requires passcode. It’s faster than turning the phone off.
That said, turning it off also works.
The reason you want to do these things is it clears encryption keys from memory and makes it harder to get at your data.
I feel like this is making people unnecessarily afraid. Most protests do not require you to do anything special with your phone. If you expect more confrontational or destructive actions to be happening then this is a good idea but most protests I’ve been to are not like this.
I did not. I’ve been to several protests and did not take any “security precautions”, nor did most people there. It was completely safe with no reason to think there would be repression.
The point of mass resistance is that the state does not have the power to arrest us all. If they did then we would need to use different tactics. But resisting brazenly is a demonstration of power and makes such an outcome less likely in the future.
