Are you the friend of mine that I’m going to be incriminated by, when they GUESS I have a FB account and force me to give up its password? Of course I’m going to truthfully say my password is random characters that I couldn’t possibly remember. At which point they will force me to give up my master password manager password. Then they have access to all my data in the cloud which software will download before I could possibly change a single password. SO, now the only option is for ME not to go through the border!
Perhaps the only solution is to live a life that you are willing to be FULLY accountable for and “documented” by how I live it. …or not travel.
