Relevant XKCD: https://xkcd.com/1121/
Does my doppelgänger go to my workplace and do my job?
If not, there’s your answer.
If he does, I leave him to it and go read a book in the park.
Congrats, your doppelganger goes to your job and gets you fired. The monkey’s paw strikes again.
In that case, that’s the giveaway
Don’t let my boss know that I know this.
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.
This is the most D&D campaign thing I’ve ever heard, no further questions
Simple. I kill my doppelgänger, if he wins he wanted it more.
There could be only one Rusty Shackleford.
…Dwight?
Nice try, Doppelganger!
Save it for queen dopplepopolis!
I dub thee Sir Phobos, Beater of Ass.
Same as I do now, passwords. Unless they inherited my memories, in which case who’s to say I’m not the doppelganger?
Lol, I think passwords are very trival to get.
I mean, they got the ability to look like you, you gotta assume they can get CCTV footage of you typing your passwords.
I don’t see how looking like me would help them get CCTV footage, unless it’s through some sort of supernatural means. And even if they could find footage of me entering a password, they’d be hard-pressed to extract individual keystrokes from a typical CCTV quality recording. Perhaps it’s technically possible, but it’s certainly not trivial.
Well, easy, I’m the one without the moustache.
I’m pretty sure you always had a moustache …
Be too useless to merit a doppelganger. To paraphrase zhuangzi, few know the usefulness of uselessness.
I would be signing all my communications cryptographically and sharing a key in person so people can validate whether a message not delivered face to face is really from me.
Cryptography is the only correct answer
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?
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
“Something you have” is not exactly a good way to authenticate. Once they steal it, they can assume your identity (see: ID Theft)
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 doppelganger have the same tastes as me? If not, then only the real me would walk around with Amy Rose and/or Sonamy (Sonic x Amy Rose) wallpapers on all his devices without the slightest hint of shame or embarrassment.
If he has the same taste, then we’ll play SoulCalibur 3 together.
Secret handshake
I’m the one who knows how to use Lemmy.

Does my doppelganger have the same knowledge I have, or just the same outward physical characteristics?
-
Does my doppelganger possess the same physical objects I do, like an identical copy of a cell phone, say?
Think like identity theft, they transform their body to match your body, and their voice matches your voice. The only way they can get detected is if they get arrested and the authorities use a machine to verify someone’s true identity.
Don’t forget, this is the information age, they might have surveillance capabilities to monitor the way you talk, and be able to record your authentication methods.
Hmm. I’m not entirely clear here…are you saying the answer to both of the two questions is “no”? I mean, you didn’t explicitly say that the doppleganger has the same knowledge or the same possessions, but you also didn’t explicitly say that they didn’t.
Does my doppelganger have the same knowledge I have, or just the same outward physical characteristics?
They don’t have a replica of your brain, if that’s what you are asking.
They just look the exact same as you, along with your voice.
But they might have hacked your phone and started listening in to be able to mimic the way you talk.
Does my doppelganger possess the same physical objects I do, like an identical copy of a cell phone, say?
No, but they could just steal your phone, or better yet, just kidnap you and lock you away then steal your clothes too.
They don’t have a replica of your brain, if that’s what you are asking.
Okay. In that case, I think that I’d probably use that, since there will definitely be information that I could show other people that only I know. Passwords, past private memories with people I know, that sort of thing. Maybe if one is optimistic, my doppleganger could guess or somehow obtain one or two, but if we do a number of these, I should be able to pass many more of these than my doppleganger.
how about i just fuck them then 🤗
That begs the age old question… would that be incest, or masturbation?
since its a completely different person that just tries to look like you, neither. A bit of narcissism maybe.
