How to Use SecureChannel
Securely exchange messages and files with other Pro users — no passwords needed. Everything is automatically encrypted.
How Encryption Works
Message Flow
File Flow
First time: Set a passphrase
On your first visit, you'll set a passphrase. This encrypts your private key before it's stored on the server. The passphrase itself never leaves your browser.
Next time: Unlock with passphrase
On return visits, just enter your passphrase. Your encrypted private key is fetched from the server and decrypted in your browser. Works from any device.
Find a recipient and start chatting
In the 'New Message' tab, enter the recipient's Account ID (SM-XXXXXX) or email and press 'Find'. Using an Account ID, you can message anyone without knowing their email. Their public key is automatically retrieved.
Verified — public key confirmed
You can also search by email address
Send messages and files
Write your message and press 'Encrypt & Send'. You can attach files too. Everything is encrypted in your browser with the recipient's public key — not even the server operator can read it.
Continue the conversation
Switch to 'Conversations' to see all your chats. Tap any to continue in a chat-style interface. New messages show an unread badge.
