Anonymous chat without sign-up: how a password-protected room works
A 38-second animation: open a LOCK.PUB chat room without signing up, send friends the invite link and the password separately, and they join in the browser with a display name. Messages are encrypted in the browser with the room password before they are stored.

Want to chat without giving out your number?
Most group chats need your number and profile.
There's another way.
Open a chat room on LOCK.PUB.
No sign-up — just a room password.
Send your friends the invite link…
…and the password, separately.
They join in the browser — no app, no account.
Everyone picks a display name.
Talk freely — no numbers, no profiles.
Messages are encrypted in your browser…
…with the room password, before they're stored.
Someone with only the link?
No password, no entry.
Chat with a password, not a profile.
