Share Passwords Securely — Once, Then Gone
The safest way to share a password is to make it exist only once. EncryptedNote creates a one-time encrypted link — after your recipient reads it, the password is permanently deleted.
Why Email and Chat Are Unsafe for Passwords
When you share a password over email, Slack, or SMS it persists indefinitely in message histories, server logs, and backups. Anyone who gains access to those channels — now or in the future — can see it.
- Email servers keep copies for months or years
- Slack/Teams history is searchable by admins
- SMS messages are stored by carriers
- Screenshots and copy-paste histories linger on devices
How One-Time Password Sharing Works
1. Encrypt in your browser
Your password is encrypted client-side using XChaCha20-Poly1305 before leaving your device. We never see it.
2. Share a one-time link
You get a single-use link. Send it to your recipient through any channel — it's encrypted, so interception reveals nothing useful.
3. Auto-delete after reading
Once opened, the secret is permanently deleted from our servers. The link is dead. No trace remains.
Zero-Knowledge — We Cannot Read Your Passwords
Unlike email or chat platforms, EncryptedNote uses zero-knowledge architecture. Encryption and decryption happen entirely in your browser. The decryption key never reaches our servers. Even if our servers were breached, attackers would find only meaningless encrypted data.
