Whether it's gossip, a surprise party address, or a confidential tip, sometimes you need to send a message that leaves absolutely no paper trail. This is where secret message links come in.

With PassLink, it takes under 10 seconds from start to finish. There are no accounts to create, no email verification loops, and no apps to install. It is a completely frictionless web experience.
3 steps to a self-destructing message
- 1. Paste: Go to PassLink and type your private note.
- 2. Encrypt: Click the button. Your text is encrypted locally using the Web Crypto API.
- 3. Share: Send the resulting URL fragment to your friend via any channel.
Perfect for:
- Journalists communicating with sources
- Sharing door codes or lockbox combos in Airbnb networks
- Sending a quick API key to a contractor
Is it really deleted forever?
Yes. Based on zero-knowledge architecture, the server actually never reads your message in the first place. When the link is opened, the encrypted blob is deleted from the database. It cannot be recovered by you, by us, or by law enforcement.
What encryption protects your secret message?
PassLink uses AES-128-GCM encryption, the same standard trusted by banks and governments. The encryption happens entirely in your browser using the Web Crypto API before any data reaches the server. The decryption key is embedded in the URL fragment (the part after the # symbol), which is never sent to the server. This means even if someone intercepted the network traffic to our servers, they would only see an unreadable encrypted blob.
Secret message links vs other methods
Signal / WhatsApp: Signal and WhatsApp offer encrypted chat, but both require the recipient to install an app and create an account. Secret message links work in any browser with zero setup.
Email: Email is fundamentally insecure for secrets. Messages persist in sent folders, recipient inboxes, and mail server backups indefinitely. A secret link self-destructs after one view.
Slack / Teams: Slack and Teams messages are stored in company archives and searchable by admins. A secret link leaves no trace in any messaging platform's history.
Advanced options for extra security
- Password protection: Require a password before the recipient can view the message. Share the password through a different channel (like a phone call) for two-factor-style security.
- Custom expiration: Choose between 1 hour, 24 hours, or 7 days. Use the shortest window that works for your situation.
- View notifications: Get notified when someone opens your secret link, so you know exactly when the message was read and destroyed.
Frequently asked questions about secret message links
Can I send a secret message from my phone?
Yes. PassLink works on any device with a browser. No app download is required. Simply visit the website, type your message, and share the generated link.
What happens if the recipient does not open the link in time?
The message is automatically deleted from the server when the expiration time passes. Nobody, including you, can access it after expiration.
Can I send files as secret messages?
PassLink currently supports text-based secrets up to 10,000 characters. For files, consider encrypting them with a tool like 7-Zip and sharing the password through a PassLink secret link.
