You might be surprised, but for some people this feature can be life or death. My team has been actually waiting for Keybase to have this. We work in countries where some of us are regularly taken aside by the local police or armed forces and our phones are being checked to see if we have anything against the current government. We have to constantly make sure our communication has no traces. We'll be moving to Keybase very soon. Thank you for this!

I'm not entirely sure what your issue is here. Why not reprovision (either with a different provisioned device or your paper key) and give it a new name?

Because it's the same device as before. I only have one name for it.

Just call it device2?

I think the solution is pretty simple: encrypt with a one-time pad and then store the pad in a box that will burn that pad at your desired time; make sure no one can ever see the pad and your secret will be pretty safe.

And how do you make sure the box will burn at the desired time? What if someone stomps on the fuse?

Integrated timer with small nuclear power source.

Author here. I'm seeing the same comment in 4 different places on here, worded with various amounts of hostility. I now wish I had addressed this in the FAQ on the post. There's the suggestion that an exploding feature is worthless, given your partner can just take a screenshot or video of what you sent. This suggestion is missing (1) that your relationship with a partner is disproportionately okay at the time you se…

I don’t think you can turn back the clock and do studies with any sort of control nowadays. The generation using Snapchat is the one prior to mine - they saw the value from my generation getting bit over and over from text logs and pics getting posted. Sexting existed the second the technology was there for it.

I think the most succinct way to put it:

You send a message to someone whom you trust (and therefore won't screenshot). If their device is later compromised, forward secrecy ensures the message can't be retrieved.

Even revoking the compromised device is insufficient, as they could retrieve your chat history long before the user realizes they've been pwned.

Can you make that disclaimer obvious in the software? "Keybase exploding messages only work if who you're chatting with doesn't have a hostile client or intent"

That would come uncomfortably close to the toothpick instructions in the Hitchhiker's Guide to the Galaxy series (http://hitchhikers.wikia.com/wiki/Wonko_the_Sane). Does anyone think that technology can stop people from divulging secrets?

There's a theory about this: https://en.wikipedia.org/wiki/Risk_compensation > "Risk compensation is a theory which suggests that people typically adjust their behavior in response to the perceived level of risk, becoming more careful where they sense greater risk and less careful if they feel more protected. Although usually small in comparison to the fundamental benefits of safety interventions, it may result in a…

Yup, that's basically what I'm getting at, thanks for the links!

So, I'm okay with risk compensation if people are net doing better. I don't think that "if even one person is hurt by this, that's too much" is a meaningful basis for decisions, especially when there's a risk that even one person will be hurt by not doing the thing. So at the risk of reducing people to numbers, if, say, 100 teenagers send sexts when they otherwise wouldn't have and get screenshotted, but 1,000 teenagers send sexts when they otherwise would have sent them to a non-disappearing-by-default client, and now their photos don't get copied because of social pressure / high-but-not-impossible technical barriers, that still seems like a clear win.

That's the sort of data that I think would be very interesting to inform good engineering decisions, and also pretty impossible to get.

Don't forget a major reason for message accumulation: laziness. People often just don't bother to delete private messages. Especially true after long conversations because there might be stuff to keep in there somewhere.
