Great for Wi-Fi codes, surprise plans and love notes. Encrypted on your device, never stored. - Author: Nebula - Tags: Privacy & Safety, Security Wi-Fi passwords, door codes, account numbers, the login for a shared streaming account: we text these to people constantly, and they sit in plain text in chat histories, cloud backups and lock-screen previews long after anyone needs them. Our free [Secret Message](https://kcnebula.com/message) tool gives you a better way. You write the message, lock it with a password, and send a link. Only someone with the password can read it. ## How it works 1. **You write the message and pick a password.** Your browser locks the message on your device with AES-256 encryption. 2. **The locked message goes inside the link.** It sits after the "#" in the address, and browsers never send that part of a link to any website, ours included. There's no database, so nothing is stored anywhere that could leak. 3. **The other person opens the link and types the password.** The message is unlocked on their device, and the page immediately wipes the locked part from their address bar. ## What people use it for ### Everyday stuff - **Wi-Fi passwords and door codes** for guests, dog sitters and the cleaner, without leaving them in a group chat forever. - **Account logins** for a shared streaming or utility account. - **Bank details or an address** you'd rather not type into a plain email. ### Between friends - **Surprise party plans** that the guest of honor can't read if they glance at someone's phone. - **Gift lists and Secret Santa wishes**, shared only with the person doing the shopping. - **Scavenger hunts and escape-room games:** print the QR codes as clues and give out the passwords as answers to riddles. - **Spoilers, bets and predictions:** lock your guess now, share the password after the finale or the big game. ### Couples and secret admirers - **Love notes** only your person can open. Make the password an inside joke, the name of your first date spot, or the song from that road trip. - **Anniversary surprises:** hide the plan, or the reservation details, behind a QR code tucked into a card. - **A secret admirer note** that only opens once you've told them the password in person. ### Spy stuff (a bit of history, not a how-to) Locking a message so only one person can read it is about as old as messages. Spies have used invisible ink, book ciphers, one-time pads, "dead drops" where a note is hidden for someone to pick up later, and radio stations that read out strings of numbers. Secret Message is a modern cousin of the dead drop: the link can be left anywhere, and it's useless without the password. That said, the spy-movie uses are the frowned-upon ones. Don't use it to hide things from people who have a right to know, to harass anyone, or to break the law. And if a stranger sends *you* a "secure message" asking for money, passwords or card details, that's a scam, not a spy. ## Step by step 1. Open [Secret Message](https://kcnebula.com/message) and type your message. 2. Choose a password, or press **Make a strong one**. 3. Press **Lock & make link**. 4. Copy the link, share it, or show the **QR code** for someone standing next to you to scan. 5. **Send the password a different way.** If the link goes by email, send the password by text or say it out loud. ## Good to know - **Links can't be deleted or set to expire.** Nothing is stored on a server, so there's nothing to delete. Without the password, though, the link is just scrambled text. - **Use a real password.** Anyone holding the link can try to guess it, so "1234" isn't good enough. The built-in generator makes one that can't realistically be guessed. - **Keep messages short.** Up to 10,000 characters fit, but some chat and text apps cut off very long links. Email handles long ones best. - **Be wary of strangers.** If someone you don't know sends you a "secure message" asking for money, passwords or card details, it's a scam, whatever tool they used. ## For files, use the File Locker Need to protect a document or photo instead of a few lines of text?
