Share sensitive data with self-destructing short links that leave no trace.
1tn.me provides a secure way to share passwords, tokens, API keys, credit card details, and more. Traditional email or instant messaging can expose this data to interception, but with 1tn.me, your note reaches its intended recipient safely. No ads. No registration required.
Fill out the form by entering your sensitive information, selecting the link lifespan, and choosing whether to receive a read notification. Generate your short URL and share it with the recipient through your preferred communication method. The recipient can open the link once, as long as it hasn’t expired. After that single use, the note is permanently erased, making it ideal when you need to send API keys safely or transmit other sensitive details. If you enabled notifications, you will receive an email when it’s accessed.
1tn.me also includes a QR code generator and a URL shortener. Use these features to simplify link sharing, accessible through the ☰ Menu in the top right corner.
Standard emails or chat messages can be stored, copied, or even hacked. One-time notes solve this problem by making your information available only once. One-time notes protect passwords, PIN codes, and API keys from leaks, keep private business or personal details off permanent storage, prevent messages from being reused or read more than once, and work as a one-time link to share passwords securely without creating an account.
One Time Note is built for anyone who values privacy. Common use cases include IT teams exchanging server credentials securely, businesses sending invoices or confidential billing information, developers distributing API tokens or secure keys, and friends sharing confidential notes or private links. With one-time notes, sensitive information disappears after it is accessed, reducing long-term risks - a safer choice than email when you need the best alternative to email for sensitive data.
To get the most security out of 1tn.me, it is best to choose the shortest possible note lifespan. Share links only with trusted recipients, and enable notifications if you need confirmation that the note has been opened. Avoid storing information long term, because 1tn.me is designed for short-lived, self-destructing notes for privacy.
