Everything you need to get started and stay private.
Visit the Sign Up page and click "Download Key File". A unique
.key file will be downloaded to your device. This is your identity —
treat it like a password.
On the Sign In page, click the upload area and select your .key file.
You'll be authenticated instantly — no password, no email needed.
Once signed in, you'll see all online users. Click any user to initiate a private, encrypted peer-to-peer connection.
The other user will receive a connection request. Once accepted, your encrypted WebRTC tunnel is live. Send text, files, and images directly.
Your .key file is a 96-byte cryptographic token that acts as your complete identity
on Pitopi. It contains a random token and a salt, combined to create a unique SHA-256
fingerprint.
Critical: If you lose your key file, you lose access to your account permanently. Pitopi has no recovery mechanism — this is by design. Back up your key file in a safe place.
Your key file must be exactly 96 bytes. Never modify, rename (except the extension), or compress it. Corrupted files will not authenticate.
