Secure Ephemeral Share Links: Passphrase Protection & Recipient Domain Restrictions

The Danger of Sharing Passwords via Slack, Email, or Chat

Sharing credentials in plain text over Slack, Teams, email, or messaging apps creates permanent security vulnerabilities. These messages remain searchable in chat history, cloud backups, and corporate email logs indefinitely.

Vaultify’s Secure Share Links eliminate this risk by converting any vault item into an ephemeral, encrypted, tamper-evident link.

1. Expiration Modes

• Time-Based Expiration: Links automatically expire after a set duration (15 min, 1 hour, 24 hours).
• Single-Use Burn Mode: Self-destructs immediately upon first viewing. Once opened, the cryptographic token is purged permanently.

2. Passphrase Protection

Enforce a secondary passphrase that recipients must enter to unlock the secret. To prevent brute-force attacks, Vaultify automatically burns and destroys the link after 5 consecutive failed attempts.

3. Recipient Email & Domain Restrictions

Restrict access to a specific email address (e.g. [email protected]) or entire corporate domain (e.g. @acme.com). The recipient must verify their identity before unlocking the secret.
