KPFsecret: Self-destructing Encrypted Notes

kpfsecret-snipped site-screenshot

KPFdigital announces the launch of our self-destructing notes website:

This website allows you to securely send PINs, messages, passwords, or other sensitive or private information.

All notes are fully encrypted, and then permanently destroyed immediately after viewing.

To Use*:


  1. Type or paste your note into the box provided
  2. Click the Submit Secret Note button
  3. Copy secret link provided and send to recipient via email or text message

Your recipient simply clicks your link in their email or text app, thereby revealing their secret note on the KPFsecret website.

After the note is viewed once it is completely and permanently deleted. Subsequent clicks on your link will only lead to an empty page.

*Alternately, for extra-extra security you may create a passphrase which the recipient must enter after clicking the link you send. Typically, the passphrase can be sent by separate method to help prevent unauthorized access of your link if more than one person has access to the recipient’s email.

Why Did We Make This?

At KPFdigital we’re careful to always use industry best practices when it comes to internet security. We go to great effort to create and use only highly secure and different passwords for all online accounts.

We made the KPFsecret website because as web developers we frequently need to send passwords or other sensitive account information that we’ve created for our customers during a project. (It’s also a way for our customers to send us info securely as well.)

We prefer not to ever send important domain, mail, or other account passwords via email because that information may remain sitting in the recipients inbox forever. If the email account is ever compromised, that information could be stolen and used inappropriately.

Sending this type of information via a self-destructing note leaves no electronic trace of the info anywhere, in neither the sender’s nor recipient’s email boxes.

Safe Password Management

At KPFdigital, we make good use of a secure password manager application for securely storing and retrieving passwords for all types of online accounts. We like the 1Password app from Agile Bits, and use it on our desktop and mobile devices alike. We highly recommend that you also utilize such an app, as it will allow you to have secure and different passwords for all websites, while providing secure and easy access to that info.

KPFsecret is made from the free and open source Python web application d-note. More info about how the website works can be found here: Security, FAQs, About.

You are free to use the KPFsecret website, however continued operability or existence of this website is neither offered nor guaranteed.
