So this was an xkcd cartoon  from a couple of years ago, and the cartoonist suggests that we should all use pass phrases, and if you look at the second row of this cartoon, you can see the cartoonist is suggesting that the pass phrase "correct horse battery staple" would be a very strong pass phrase and something really easy to remember.
Ovo je xkcd strip star nekoliko godina gdje crtač predlaže da bismo trebali koristiti fraze kao lozinke, i ako pogledate drugi red crteža, vidjeti ćete crtačevu ideju da bi fraza "ispravan konj baterija spajalica" bila vrlo jaka fraza-lozinka i lako pamtljiva.
