I reset my passwords regularly, so this example doesn't provide access to anything of mine, except my old all in one router's wifi that's been sitting in a box in my basement for years. Hun$@ngF0rM3g-K@rp3_W19m This was a base password I used for about two or three years, altering the W19m ending to be a familiar measurement value for me, like walking 19 meters. It's actually lyrics from a song "Hun sang for meg", from Norwegian band Karpe Diem (song name is "Byduer i dur"). It falls into the problem of replacing letters with alike symbols, but that provides the complexity requirement, while also having enough length to be secure even without doing letter replacements. My worst passwords are often for the things I should really keep most secure because they have the dumbest restrictions that cripple complexity. 8-16 characters long .. okay, there goes ALL the normal password bases I use, most my passwords are 24-58 characters long. Only - _ ! . for special characters .. what the actual f**? Why? WHY? This is for my online medical account, WHY!?!?
