Sometimes you need to send a private message, an address, or a secret without forcing the recipient to download a new secure messaging app. Here is how to do it directly from your web browser.
How web-based encrypted text messages work
Instead of sending the text directly, tools like PassLink create an encrypted container. The key to unlock that container is hidden in the URL link. You send the link, they click it, and the text decrypts locally on their device before self-destructing.
Step-by-step guide to sending an encrypted text
- 1. Open PassLink in any browser (desktop or mobile).
- 2. Type or paste your sensitive text message.
- 3. (Optional) Set a password for an extra layer of 2FA-style security.
- 4. Click "Create Secret Link" to encrypt the text.
- 5. Send the generated link via SMS, iMessage, WhatsApp, or any other channel.
Why standard SMS text messages are not secure
Standard SMS messages are not end-to-end encrypted. They are stored in plain text by telecom providers, can be intercepted via SIM swapping, and remain on the recipient's device indefinitely. By sending a PassLink URL instead, the actual message content bypasses the telecom networks entirely.
