Canada

Turn off your phone before going through customs or tsa. They can’t compel you to give your password out, but biometrics don’t fall under that category.

If you really need to go to the US - Don't bring any electronic devices with you through security or while transitioning through borders.

Leave your devices at home. Bring a single function camera with you if you want.

Once you get across the border ... buy a new or used phone. If you have friends or family waiting for you, ask them to get you a phone, maybe even an old phone or get them to buy a used phone that you can use during your stay (pay them to get it of course).

Set up your new phone - load your data through cloud based systems ... if you are organized enough, you can set up a cloud based password manager to handle all your other data services.

Then when you leave, reformat and reset your phone and either try to sell off the phone you just bought, give it away or just toss it.

Go through security again without a device.

My company isn’t organizing any off-sites to the US for my remote first company anymore because of this shit lol. I think partially because nobody outside of the US would even go

Thats why you should use a Google Pixel with GraphineOS and a unique 20+ digit password (along with a secure VPN like Mullvad)

If you bring a burner phone and they search it and see nothing on it, they'll think that suspicious too and might deny entry.

Don't keep anything incriminating on your phone, yeah american border guards but also the fucking RCMP likes to grab phones.

Wondering when my publishing record qualifies me for asylum.

I thought that was basic opsec. Burner phone with a week of use, paid in cash on you. Real phone (if you need it) in a bag, battery removed and separate by any means. That's not just crossing borders, that's anything longer than a city bus.
