How to create a private paste link with a password
Add a password to a paste so only people who know it can open the link. A guide to creating private, password-protected paste links.
A private paste link restricts access so only people who know the password can open it. This is useful for sharing sensitive information with a specific person without exposing it to anyone who stumbles across the link.
Open a new paste
Go to nullpaste.org — no account or sign-up required.
Enter your content
Type or paste the text or code you want to share privately.
Set a password
Scroll to the Password field and enter a password. NullPaste hashes it with Argon2 on the server — the plain-text password is never stored.
Create and share
Click Create paste and copy the link. Share the link and the password separately — for example, send the link in email and the password in a chat message.
Recipients enter the password to open it
Anyone who opens the link is prompted for the password. Without it, the content is not shown.
Tips for private sharing
- Send the link and password through different channels — if one channel is compromised, the paste is still protected.
- Set an expiry so the paste disappears automatically after the recipient has read it.
- For maximum privacy, combine a password with end-to-end encryption — the server then cannot read the content even if it receives a request.
- Use burn-after-read to ensure only one person can ever open the paste, even if the link leaks afterward.
Password vs encryption
Password protection controls access — only people with the password can open the paste, but the content is stored on the server in a form the server can read. End-to-end encryption goes further: the server stores only ciphertext and cannot decrypt it under any circumstances. For highly sensitive secrets, use encryption; for general-purpose private sharing, a password is usually sufficient.
