Your one-time secret link is ready

This QR encodes the same one-time link shown above.
This link works only once. After it is opened, the secret is permanently destroyed. Even we cannot read it because encryption happens in your browser.
Share Secrets Securely with Encrypted One-Time Links
1time.io is a free, open-source tool for sharing passwords, API keys, and files through encrypted, self-destructing links. Messages are encrypted in your browser using AES-256-GCM — the server never sees your data. Each link works once, then the secret is permanently deleted. No signup required.
Use it to share passwords securely, send database credentials to a contractor, deliver one-time file links up to 10 MB, or transmit any sensitive text without it lingering in Slack, email, or chat history.
End-to-end encrypted
AES encryption happens in your browser. The server only stores ciphertext.
One-time access
Each link works exactly once. After reading, the data is permanently deleted.
Auto-expiry
Links self-destruct after 1 to 30 days, even if nobody opens them.
One-Time File Sharing
Send encrypted files through one-time download links without exposing filenames or contents.
Password Generator
Create a strong, high-entropy password in your browser for critical accounts.
QR Code Sharing
Reveal a one-time QR code for nearby or cross-device password sharing.
CLI
Share secrets from your terminal. printf 'secret' | 1time send
How it works
Type or paste your secret above. 1time.io encrypts it with a unique key directly in your browser. You get a one-time link containing the decryption key in the URL fragment, which is never sent to the server. Share it with your recipient. Once they open it, the secret is decrypted locally and permanently deleted from our servers.
How self-destructing links work
A self-destructing link — also called a one-time link, single-use link, or disappearing link — is a URL that reveals its content exactly once. The recipient clicks, reads the secret, and the server permanently deletes the data; the same one-time URL becomes a dead 404 forever after. 1time.io generates these one-time links for free, with end-to-end encryption handled in your browser, so even we never see what you share. Whether you call it a self-destruct link, a one-time secret link, or a disappearing message, the mechanism is the same: encrypt locally, share once, destroy on read.

Perfect for sharing
Passwords, API keys, SSH keys, private notes, access tokens, WiFi passwords, two-factor backup codes, database credentials, configuration secrets, or any text you need to share securely just once.
