OTP-Link
Share secrets securely and easily
Passwords don’t belong in emails and chats in plain text. OTP-Link encrypts them and turns them into a short-lived link that can only be opened once.
This tool needs an up-to-date browser with JavaScript.
Current versions of Firefox, Chrome, Edge and Safari work.

-
Encrypted in the browser
Encryption and decryption happen on your device. The content never ends up on our server.
-
Expires on its own
You choose 1 hour, 1 day or 1 week. After that, the link can no longer be opened and the entry is deleted.
-
Exactly one view
The entry is deleted the first time it is opened. Anyone who clicks the link after that only sees that it has been used up.
-
Easy to share
Copy the link and send it by email, chat or SMS. The recipient only needs a browser.
-
No account needed
No sign-up, no email address. Our database holds nothing that could be used to open a message.
-
Verifiable code
Our code is unminified and readable by anyone. That way, anyone can check what happens in your browser.
