Share a password securely
Sending a password over email or chat leaves a readable copy sitting in inboxes and message history for as long as the thread exists. classified lets you share a password securely with a one-time link: the password is encrypted in your browser, stored only as ciphertext, and destroyed after it is viewed once.
Why not just send the password in chat?
Plaintext passwords in email, Slack, or a support ticket are easy to forward, search, screenshot, and back up. They tend to outlive the moment they were needed for. A one-time link reduces that blast radius: there is no readable password stored on the server, and the link stops working after the first successful reveal.
How to send a password securely
1. Paste the password
Type or paste the password into a new note. Encryption happens locally in your browser before anything is uploaded.
2. Create the one-time link
classified returns a single-use link. The server only ever holds the encrypted payload, not the readable password.
3. Send the link
Share the link with the recipient. For extra protection, add a separate password and send it over a different channel.
4. It self-destructs
After the recipient reveals it once, the stored copy is consumed, so the same link cannot expose the password again.
Good habits when sharing credentials
- Rotate the password after the recipient has used it, especially for shared or temporary accounts.
- Verify the recipient through a separate channel when identity matters.
- Use a password manager for long-term storage; use a one-time link only for the hand-off.
