How It Works
Sharing secrets securely takes just four simple steps.
Create Your Secret
Enter your sensitive information - passwords, API keys, text, or upload a file. Choose your security settings.
Get Your Secure Link
KeySlip generates a unique, encrypted link. Copy it or scan the QR code to share.
Share Safely
Send the link to your recipient through any channel - email, chat, SMS. The secret stays encrypted.
Auto-Destruct
Once viewed (or when time expires), the secret is permanently deleted. No traces left behind.
Features
Everything you need to share sensitive information securely.
End-to-End Encryption
Your secrets are encrypted in your browser before being sent to our servers. We never see your unencrypted data.
Auto-Expiring Links
Set custom expiration times from 1 hour to 999 days. Links automatically self-destruct after the time limit.
View Limits
Control how many times a secret can be viewed. Once the limit is reached, the secret is permanently deleted.
Password Protection
Add an extra layer of security with a passphrase. Recipients must enter the password to view the secret.
File Sharing
Securely share images, documents, and other files up to 50MB. Files are encrypted just like text secrets.
Burn After Reading
Secrets can be manually destroyed at any time by the sender, even before they're viewed.

Best Practices
Tips for sharing secrets securely.
Use password protection for highly sensitive data
Share the password through a different channel than the link.
Set the shortest expiration time you can
The less time a secret exists, the smaller the window for interception.
Use single-view for one-time passwords
Setting view limit to 1 ensures only the intended recipient sees it.
Don't share the link and password together
Send them separately to reduce risk if one channel is compromised.
Frequently Asked Questions
Common questions about KeySlip.
Is KeySlip really secure?
Yes. KeySlip uses client-side encryption, meaning your secrets are encrypted in your browser before they ever reach our servers. We use AES-256 encryption, the same standard used by banks and governments. We physically cannot read your secrets.
What happens after a secret is viewed?
Once a secret reaches its view limit or expires, it's permanently deleted from our servers. There's no way to recover it - not even by us. This ensures your sensitive information doesn't linger.
Can I delete a secret before it's viewed?
Yes! After creating a secret, you'll receive a receipt page with a 'Burn Secret' button. Click it to immediately and permanently destroy the secret, even if no one has viewed it yet.
What types of files can I share?
You can share any file type up to 50MB - images, PDFs, documents, archives, and more. Images will display inline when viewed; other files can be downloaded by the recipient.
Do I need an account?
No! KeySlip works without an account for basic usage. Creating a free account gives you access to your secret history, higher limits, and additional features.
Is KeySlip free?
Yes, KeySlip is 100% free for personal use with generous limits. We believe secure communication should be accessible to everyone.
