Let guests connect to your WiFi without reading out long, complicated passwords.
Modern WiFi passwords are intentionally long and unwieldy. The router-default 24-character mixed-case-and-symbols string is a real defense against brute-force attacks — but it is also fundamentally hostile to being read aloud, retyped from a sticky note, or pulled from a printed sheet on a fridge. The friction-reduction shortcuts most people use (printing on a poster, texting it to guests, leaving it on a whiteboard) all undermine the password's security.
Once a guest has the password, they have it forever — most modern operating systems remember WiFi credentials by default and re-join automatically the next time the SSID is in range. A guest from three years ago who walks past your house can still rejoin the network, and (if they are so inclined) probe your printers, NAS, smart cameras, and IoT devices. Even friendly guests are a permanent attack surface.
PasteOnce changes the WiFi handoff to a single-shot transfer. Paste the password, send the link via whatever channel the guest already uses, the guest reads once, the ciphertext is gone, and nothing about the password remains on either device beyond what they typed into their phone's WiFi settings. Combine with a separate guest-network SSID and you have something close to clean access management for casual visitors.
Client-side encrypted. We can't see your data.
Your data is encrypted in your browser before it leaves your device.
Messages are automatically deleted after being read once.
We never see your data. Only encrypted blobs pass through our servers.
Links work exactly once. Refresh the page and it's gone forever.
Your sensitive data is encrypted in your browser using AES-256-GCM. The encryption key is generated randomly and never sent to our servers.
Only the encrypted blob is stored in our database, with an automatic expiration time. We literally cannot read your data.
When your recipient opens the link, the encrypted data is fetched and immediately deleted from our servers using an atomic Redis GETDEL. The key in the URL hash decrypts the message in their browser.
Almost every modern router supports a guest network or VLAN-isolated SSID. Guest devices can reach the internet but cannot reach your printers, NAS, or smart-home devices. Use it for everyone who is not a household member.
For homes, monthly is enough. For offices, weekly during high-visitor periods. For events, single-use and rotate immediately after. PasteOnce makes the rotation handoff frictionless.
Cafes, conferences, and offices benefit from captive portals that require fresh acceptance per device-day. Many enterprise APs and modern consumer routers (UniFi, Eero Pro, Aruba Instant On) support this out of the box.
Most routers show every device that has connected in the last N days. Skim it; remove anything you do not recognize. The MAC randomization on modern phones makes this less precise than it used to be, but it still surfaces stale corporate guest devices.
An auditor or vendor is on site for the day. PasteOnce the guest-network password, they read the link on arrival, you rotate the password the next morning. No printed sheet, no Slack DM, no sticky note on the conference-room whiteboard.
Welcome message to the incoming guest includes a PasteOnce link to the WiFi password, valid for 24 hours. They tap on arrival, the ciphertext is gone, and the next guest gets a fresh link with the rotated password.
Hundreds of attendees need network access for the day. Generate one link per attendee from the registration system, pre-scheduled to expire by end of day. No QR-code phishing surface, no shared password leaking on a hashtag.
Your in-laws come for dinner and need WiFi for the kids' tablets. PasteOnce, text the link, kids' tablets connect, and the password is not sitting in a forwarded text-thread for the next decade.
QR codes work well for in-person, single-room handoffs (a printed code on the front desk works fine). PasteOnce is better for remote or asynchronous handoffs — guests who have not arrived yet, contractors who want the password before driving over, or family checking in remotely.
WPS has had documented security weaknesses for over a decade and most security researchers recommend disabling it. The guest-network feature itself (separate SSID, isolated VLAN) is great — combine it with PasteOnce-style password sharing instead of WPS.
Bigger, by far. Never share router admin credentials over any channel — change them on first setup and store them in a password manager. PasteOnce is for the WiFi password, which is fundamentally a shared secret; the admin password is fundamentally yours alone.
One hour for a guest already on the way; 24 hours for a guest traveling to you; the shortest reasonable window for a vacation-rental check-in. Longer than 24 hours is rarely justified — generate a fresh link each time instead.
