Key in the URL fragment
The decryption key is after the # and is never sent to our servers.
Secure Send
Share a secret once. Then it’s gone.
Send a password, note or file to anyone as an end-to-end encrypted link. The key lives only in the link, the content burns after the last view, and you can revoke it any time.
Key only in the link Burn after reading No account needed to open
Expiry and view limits
From one view to 25, and from one hour to 30 days. The last view deletes the ciphertext.
Optional passphrase
Add a passphrase and send it separately. Wrong guesses never burn a link; ten lock it.
Text or files
Send a secret or a file up to 5 MB, encrypted in your browser.
Revoke any time
Revoking deletes the encrypted content immediately.
Admin controls
Organizations decide who may create external links, and every send is audited.
Questions

No. Anyone with the link (and passphrase, if set) can open it in a browser.
Can Passkey-X read what I send?
No. Content is encrypted in your browser with a key that only exists in the link you share.
