Share Secrets with Encrypted One-Time Links
1time.io creates encrypted one-time links that automatically self-destruct after being read. End-to-end encrypted in your browser before anything leaves your device — we never see your data.
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.
Password Generator
Create a strong, high-entropy password in your browser for critical accounts.
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 using AES encryption directly in your browser. You get a one-time link containing the decryption key. Share it with your recipient — once they open it, the secret is decrypted in their browser and permanently deleted from our servers.
Perfect for sharing
Passwords, API keys, SSH keys, private notes, access tokens, two-factor backup codes, database credentials, configuration secrets, or any text you need to share securely just once.
