You have a bunch of onion addresses, usernames, passwords, notes that you don't want seen. Sure, you can develop a personalized pnemonic saved on an encrypted drive hooked up to a homemade detonation device you can activate by saying "Keanu's ocelot" in a southern accent. But is that as fun as....an INVISIBLE INK pen?? I'm talking the dual-sided pens where one side writes in invisible ink and the other is a UV-light which illuminates the writing when you need it. Now, I'm NOT suggesting you write all this on a single square paper that you then leave in your drug safe or taped to your DNM laptop. That is indeed suspicious. But what about writing over the dedications page on one of the novels on your bookshelf, or on the back of the photo framed on your desk? (For some of you, you may have to substitute novel with math textbook, or coloring book maybe? you get the idea). But joking aside, I feel like some of us start out with great, by-the-books OPSEC and then over time start to cut corners when we're in a hurry or lazy. Maybe this would help? Am I crazy?
I'm just happy you reminded me of invisible ink!
