How to Share a Wi-Fi Password Securely

You have guests coming over, a new employee joining, or an Airbnb check-in — and you need to share your Wi-Fi password. Most people text it in plaintext, leaving it permanently in the recipient's message history (and backed up to iCloud, Google, etc.). A better pattern: send a SecureMint memo that self-destructs after it's read once. The password exists only long enough to be copied once, then vanishes.

Create a Burn-After-Reading Memo
SecureMint uses zero-knowledge design. The server cannot read your data.

Steps

1

Open SecureMint /memo

Go to securemint.app/memo. No account needed for a single memo.

2

Paste your Wi-Fi SSID and password

Example: 'SSID: HomeNet5G / Password: correct-horse-battery-staple'. You can add any other tips like router IP or guest network name.

3

Enable 'burn after reading'

Toggle burn-after-reading on. The memo will be permanently deleted from the server the instant the recipient opens the link.

4

Send the one-time link to your guest

Copy the link and send it via iMessage, LINE, email, or AirDrop. Even if their phone is stolen later, the link will be dead.

Why It's Secure

  • End-to-end encrypted with AES-256-GCM — the server stores only ciphertext.
  • The decryption key lives in the URL fragment (#) and never reaches our server.
  • After the memo is read once, it is wiped from storage — no recovery.
  • Set an optional expiration (1 hour to 7 days) as a backup in case the guest never clicks.

FAQ

What if my guest never opens the link?
Set an expiration when you create the memo (e.g., 24 hours). If unread by then, the memo auto-deletes. Just send a new one when they arrive.
Can I use this for a guest Wi-Fi network code at an event?
For single recipients yes — but burn-after-reading means only one person can open each link. For multi-recipient distribution, disable burn mode and set an expiration instead, or use a dedicated guest-network QR code.
Why not just use the iOS 'Share Password' feature?
iOS Share Password only works between iCloud-signed-in iPhones in close physical proximity. It fails for Android guests, PCs, and remote check-ins like Airbnb. SecureMint works on any device with a browser.
