1time — One-Time Secret Links

Encrypt selected text in your browser and copy a one-time link. Supports 1time.io and self-hosted servers.

Share a password, API key, or private note as an encrypted one-time link — without leaving the page. Select any text, right-click, and choose "Share as one-time link" (or press Alt+Shift+S). 1time encrypts the selection in your browser and copies a self-destructing link to your clipboard. The recipient opens it once, then the secret is permanently deleted. WHY 1TIME • One-time links — each link works exactly once, then the data is gone. Nothing lingers in chat history or inboxes. • Zero-knowledge encryption — text is encrypted in your browser with AES-256-GCM. The decryption key stays in the link and never reaches the server. Even the server operator cannot read your secret. • Right from the page — no tab switch, no pasting secrets into a website. • Keyboard shortcut — Alt+Shift+S shares the current selection instantly. • Self-hosted ready — point the extension at your own 1time server in the options and keep secret sharing on your own infrastructure. • Free, no signup — uses 1time.io by default, no account required. GREAT FOR Sharing database URLs in a code review, handing a colleague an API key, sending recovery codes, passing along SSH snippets, or any moment a secret is already on your screen and you need a safe, single-use way to pass it on. HOW IT WORKS 1. Select the text you want to share. 2. Right-click → "Share as one-time link" (or press Alt+Shift+S). 3. Your browser encrypts the text and uploads only the ciphertext. 4. An encrypted one-time link is copied to your clipboard. 5. The recipient opens it once; the secret is decrypted in their browser, then deleted. The link is deliberately kept out of the page — the clipboard copy happens in a private extension context so page scripts can never read it.
