Emailing Passwords Is Insecure. Here's the Fix.

Share credentials with zero-knowledge encryption. The decryption key never leaves your browser, so not even CloakBin can read what you share. Auto-delete ensures passwords don't linger.

How It Works

1

Paste Your Password

Type or paste the credential you need to share into the editor.

2

Encrypted in Browser

AES-256-GCM encryption runs entirely in your browser before anything is sent.

3

Share the Link

Send the generated link via any channel. The key is in the URL fragment.

4

Auto-Delete After Viewing

Enable burn-after-read so the password is destroyed after a single view.

Who Uses This

Team Onboarding

Share staging credentials, API keys, and database passwords with new team members without leaving a trail in email or chat.

Client Handoff

Send login credentials to clients securely. The link self-destructs, so there is no sensitive data sitting in their inbox.

IT Helpdesk

Reset passwords and share temporary credentials with end users. Auto-delete ensures the temp password cannot be reused.

Emergency Access

Share break-glass credentials during incident response. Time-limited links ensure emergency access does not persist.

Why URL Fragment Keys Are Safe

  • URL fragments (#) are never sent to the server per the HTTP specification.
  • Encryption and decryption happen entirely in your browser using the Web Crypto API.
  • The server only stores ciphertext it cannot decrypt. Even a database breach reveals nothing.
  • No server-side logs, analytics, or third-party scripts ever see the encryption key.
