    You authenticate either with something that you have (physical key, for example), something that you know (passwor for example), or something that you are (biometrics, basically).

    Dopplegangers rule out that last one, but the previous two still work fine

        That also goes for what you are. Biometric security has been rendered nearly useless since everybody and their mother started using it without giving a single shit about securing that data

    Does my doppelgänger go to my workplace and do my job?

    If he doesn’t, there’s your answer.

    If he does, I’ll leave him to it and go read a book in the park.

    Some years back I was in a D&D campaign where doppelgangers became a major ongoing concern. It turned out that in that case doppelgangers built up their image of the person they wanted to mimic through careful observation, but thanks to the general prudishness of society doppelgangers rarely ever caught glimpses of peoples’ genitals. So we ultimately came up with the “crotch check” system. Doppelgangers usually couldn’t form plausible genitalia.

    My doppelganger will provide PII before I do

    Whichever one folds and tells you an actual identifying characteristic first is the fake

      The inquisitor sighs in exasperation.

      “It’s been 36 hours. You’ve each had one granola bar and a bottle of Pepsi since you got here. At some point, one of you has to prove you’re real.”

      Left Starman says “I invoke the 5th.”

      Right Starman says “I want a lawyer.”

      "You’re not under arrest! We’re just trying to figure out which one of you is real. You gotta give us something.

      Both Starmen simultaneously state “I don’t talk to police.”

      The interrogation continues for a further 17 hours before Left Starman gives in. “My cat’s name is Iris, you can call my roommates and verify it.”

      “You dumb son of a bitch,” Right Starman says, “that’s just what I tell people online.”

    I’m already an identical twin and it’s a nightmare even having a different first and middle name but same everything else.

    I think we’re just living with a second set of identical twins?

    • fingerprints are not genetic, but are formed by the movement of the fetus in the womb. while they are not a reliable way to identify someone out of a general population (the likeness is about 1:10000; there have been wrongful convictions based off of fingerprint data) they can be used to differentiate two individuals.
    • almost everyone has some insignificant scarring on the hands or face that’s created after birth and which is tied to some stupid story about cutting cheese or whatever.
    • everyone has some weird fetish. if you don’t think your fetish is weird, it’s because you’re in company that shares it.

    I’ve had several occasions where I’ve seen doppelgangers out in public in my city but I’m 99% sure this is because I was a sperm donor baby. It was totally anonymous in the early 90s.

    Could do one of those DNA test things but I have less than 0 interest in meeting a bunch of half siblings. Sounds messy. Already got two parents who I’m happy with.
