How to send a secret message that disappears

Need to share something private without it sitting in a chat history forever? Here is how self-destructing chats work, and what they can and cannot protect.

Sometimes you need to say something once and not have it sit in a chat history for years: a private worry, a surprise plan, a sensitive detail you need to pass on.

Disappearing chats are made for this. Here is how to use them well.

Why chat history is a risk

Every message you keep is a message that can be found later, if a phone is lost, an account is broken into, or someone scrolls back through an old chat. The less you keep, the less can leak.

How to send a message that vanishes on DiffWeb

  1. Open Temporary Rooms and give your room any name.
  2. Choose how long it lasts: 15 minutes, 1 hour, 6 hours or 24 hours.
  3. Share the invite link with the person you want to talk to. You can add a password, or approve each person before they can join.
  4. Talk. Messages, photos and files are end-to-end encrypted.
  5. End the room when you are done, or let the timer run out. Access is gone for everyone, on every device.

There is no sign-up and no phone number, so the conversation is not tied to your identity either.

The invite link contains the room's key, so treat it like a key. Send it only to the person you mean to talk to. If you think it went to the wrong place, you can replace the link from inside the room.

What a disappearing chat cannot protect

Be honest with yourself about the limits:

  • The other person can still take a screenshot or a photo of the screen.
  • If someone is looking over your shoulder, encryption does not help.
  • Anything you say can be remembered and repeated.

So choose who you trust, and keep the most sensitive things for people who have earned it.

Your chat. Your rules.
