How to Share a WiFi Password Securely
Give guests and staff network access without leaving the password sitting in a chat thread forever.
A WiFi password feels harmless to text or drop into a group chat, but it is a key to your network. Once it is pasted into a message, it lives in that history indefinitely, gets forwarded, and can end up on the phone of anyone who briefly borrows a device. For a home guest that might be a minor annoyance. For an office network, a print-out on the wall or a message in a shared channel is a genuine risk, because anyone on the same network is a step closer to your printers, cameras, file shares, and connected devices.
Why the sticky note and the group chat both fail
The most common ways people hand out WiFi credentials all share one flaw: the password persists somewhere you no longer control. A photo of the router label sits in a camera roll. A message in a company Slack channel is searchable by every current and future member. A whiteboard in a meeting room is visible to every visitor. None of these expire, and none of them tell you who actually read them.
A one-time link flips that around. The password is encrypted in your browser, delivered through a link that works exactly once, and permanently deleted the moment it is viewed. There is nothing left to forward and nothing left to find later.
Sharing WiFi access step by step
- Open Burn the Secret and paste your network name and password.
- Set a short expiry, for example one hour for a single guest arriving now.
- Optionally add a passphrase and tell the guest verbally.
- Create the link and send it by text, email, or QR code.
- Once they connect, the secret is gone, so nothing lingers on their device.
Everything is encrypted client-side with AES-256-GCM, so the server never sees your password. It is free, needs no signup to create a link, and works from any browser.
Extra tips for office networks
- Use a dedicated guest network so visitors never touch internal systems.
- Rotate the guest password on a schedule and share the new one with a fresh link.
- For a recurring reception setup, generate a new one-time link per visitor rather than reusing a static message.
- Keep the main network password out of any shared document entirely.
