Been using the same dumb password trick since my Hotmail days in 2004 and it still works
Back when I was a freshman at Ohio State, some IT guy at the library showed me to take a phrase I'd remember and swap the vowels for numbers, so "ilovepizza" becomes "1l0v3p1zz4." I shrugged it off for years, but after my eBay account got hit in 2019 I finally started doing it for real sites with two or three words stacked up. It's not fancy but it beats writing stuff on a sticky note. What low tech stuff are you all still hanging onto that actually holds up?
