Paranoid Mode provides enhanced security for your transfers by ensuring exclusive 1:1 communication between exactly two devices.
Paranoid Mode is an optional security feature that locks your transfer channel immediately after the first connection is established. Once locked, no additional devices can join the channel – even with the correct link or QR code.
This prevents potential eavesdroppers or unauthorized third parties from joining your transfer, even if they somehow obtain your sharing link.
Important: With Paranoid Mode enabled, if the connection drops, you'll need to create a new channel. The locked channel cannot accept reconnections.
Paranoid Mode adds several layers of security to your transfers:
Even if someone intercepts your link, they cannot join after you've connected.
The server permanently marks the channel as locked – no exceptions.
You know exactly who you're connected to – only one other device.
Combined with 1-hour channel expiry for additional security.
Here's what happens behind the scenes when you enable Paranoid Mode:
Channel Creation
When you create a channel with Paranoid Mode, the server marks it as 'secure' in its configuration.
First Connection
When the first peer connects and WebRTC handshake completes, the server locks the channel.
Channel Locked
Any subsequent connection attempts are rejected with a 'channel locked' message.
Secure Transfer
Only the two connected peers can communicate. The channel remains locked until it expires.
