“Slide to Unlock” by Ed Park
Clever. We don’t know why until the end of the story, but the narrator (in second person) is reviewing his life in passwords, all the life events that he might have used to come up with an unforgettable password. “If you could type out all your passwords, their entire silent history, they could fill a book you could read in a minute.”
I won’t say why this is happening, except to say that the ending might actually justify the use of the second person here, which I normally detest. Here, though, the narrator could very well be looking at himself as if from another plane of existence, so maybe the POV works. It’s a fun, fast read.
I’m so happy you finally found a second-person story you liked!
