So what? This boils down to you basically incriminating yourself. Lessons to learn of this:

1. Do not create these thoughts in your mind. They will attract suspicion and create the reality of you being interrogated about this.
2. Travel with a phone where you don't mind people having access to what's on there. (Once you're crossing the "border", temporarily delete the Facebook app if you have facebook for example, and delete any other app that requires Facebook login.) If you're known for crypto, reset your wallets so they are blank wallets. Don't forget your backup seed and DO NOT carry it on you :)
3. Whatever accounts they ask that you have, you don't have those accounts. You're not required to have them by law, anyways.
4. If you feel that you are being "forced" to input a password of yours, keep putting in a WRONG (but not obviously wrong) password. Do this to trigger the account reset issues and basically lock yourself out of the account. When you get "instructions sent to your email", do the same thing and keep yourself locked out.
5. Use biometric security on your devices...BUT DO NOT ALLOW THEM TO BE THE ONLY THING THAT IS REQUIRED FOR ACCESS! and of course: use a strong password. Another strategy is simply to reset your phone, and when they ask about why, simply state that it was having problems and you didn't realize that your "stuff would disappear".
6. DO NOT HAVE AN ATTITUDE OR BE AGGRESSIVE WHILE ANSWERING QUESTIONS. In their mind, this is a sign of lying and they will continue to persue you.
7. If you have an internet presence where people think you have a lot of crypto, just inform them the truth that it's just marketing on your part, and you're lying for clout. Simple.
8. If they look at your STEEM account, be truthful and say, "Ya, that's my steem account. Sorry, I don't carry my password on me. It's on a computer at home." -- AND KEEP IT THAT WAY. Have a backup plan if this is pursued, such as them "forcing" you to get a family member to have access and tell you over the phone. They'll threaten holding you there indefinitely. I can give examples of backup plans that work.
9. Finally, Power Up your STEEM so that only 1/104th of it can be withdrawn after 7 days ;)

Ultimately, if you end up in the worse case scenario, you'll be given a lot of negative pressure. Instead of giving into it, ENJOY IT! Enjoy having a completely valid excuse to have everything taken care of for you at the moment--they're not going to torture you. And if you're in a position where this is the case, then you should already be hiring consultants on what to do about these situations :)
