Key in the link
The decryption key is after the # in the link and is never sent to our servers.
Secure Send · Free
Share passwords securely, free, with one-time links
Secure Send turns a password, note or file into an end-to-end encrypted link that expires after the time and number of views you choose. It is included in every Passkey-X plan, including Free, and the person you send it to doesn't need an account.
Key only in the link Burns after the last view No account needed to open
Included free
What Secure Send includes on Free
Expiry and view limits
From one view to 25, and from one hour to 30 days. The last view deletes the encrypted content.
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, even if it hasn't been opened.
Anyone can open it
The recipient opens the link in any browser. No Passkey-X account or app is needed.
How it works
Three steps to get started
- Step 1
Write or attach
Type the password or note, or pick a file up to 5 MB. It's encrypted in your browser.
- Step 2
Set the limits
Choose when the link expires and how many times it can be opened, and add a passphrase if you like.
- Step 3
Share the link
Send the link, and the passphrase by another channel. After the last view the content is gone.

Questions
Free Secure Send FAQ
Is Secure Send free?
Yes. Secure Send is included in every Passkey-X plan, including Free. You need a free account to create a link; the person you send it to doesn't.
Does the recipient need Passkey-X?
No. Anyone with the link, and the passphrase if you set one, 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.
What happens after the last view?
The encrypted content is deleted, and the link shows that it has been used. The same happens when the link expires or you revoke it.
How big can a file be?
Files can be up to 5 MB each. They are encrypted in your browser before upload.
Can I cancel a link I already sent?
Yes. Revoke it from Secure Send and the encrypted content is deleted straight away.
