A conversation only they can open.

Only Us Two pairs exactly two people — in person with a scanned code, or remotely with a link — and encrypts every message with a key that's used once and thrown away. No accounts. No names.

Free. Runs entirely in your browser — nothing to install.

Two ways to pair, for two different risks

Pick whichever fits the two of you — both lead to the same conversation.

In person

Scan each other's code, face to face. The handshake never touches a server, so there's nothing in the middle to trick.

Remotely

Send a link to someone, anywhere. Compare a short safety number afterward to confirm nobody swapped keys along the way.

What using this actually means

01

Every message is sealed with a key that's used once and destroyed — not one shared key covering the whole conversation.

02

No name, email, or phone number, at any point in setting this up or using it.

03

Set a passcode. Get it wrong too many times in a row, and the device wipes itself completely — every pairing, every message, the passcode too.

04

Flag any message to disappear the moment it's read, or set a whole conversation to auto-delete after a set time.

05

Delete a conversation and it's gone for both of you at once — not just hidden on your side.

06

The source is open. What it does is exactly what you can read it doing — nothing is hidden from you either.

Keeping this running

Only Us Two doesn't run ads that track you. If it's useful to you, here's how to help keep it that way.
