An online clipboard with no login
You do not need an account to sync a clipboard — you need a shared secret, and an account is only one way of having one. Open this page on two devices, type the same short key on both, and whatever you copy on one is on the other's clipboard. No email address, no password, no install, no extension.
Why most clipboard tools ask you to sign in
A sync service has to answer one question: which two devices belong together? An account answers it by making both devices prove they are you. That works, and it brings along everything an account requires — an email address, a password, a server that stores which devices are yours, and a record of when they were used.
A shared key answers the same question differently. Both devices present the same short string, so the service can put them in the same room without ever learning who they belong to. The key is knowledge, not identity, and knowledge can be typed in five seconds.
That single substitution removes the sign-up form, the password reset, the email confirmation and the account database at once. It also means the service genuinely cannot tell you apart from anyone else, because it was never given anything that would.
How it works
- Open the clipboard on the first device. It generates a short key.
- Type that key on the second device, or scan the QR code it shows.
- Copy anything on either device.
- Switch to the other device and paste — it is already on the system clipboard.
The key never leaves your browser. What reaches the relay is
SHA-256(key) — a hash used purely as a room address —
along with your text already encrypted with AES-GCM under a key
derived from the one you typed. The relay routes ciphertext between
two connections and writes nothing to disk. Files skip it altogether
and travel directly between the two browsers over WebRTC.
What no account actually costs you
Every no-login service trades something away, and a page that will not say what is hiding it.
The trade, stated plainly
- The key is the only credential
- There is no second factor and no identity behind it. Anyone who learns the key can read that session while it is open.
- Nothing is kept
- No account means no server-side history. Close the session and it is gone — that is the design, not a limitation to work around.
- No recovery
- Forget the key and there is nobody to ask. Generate a new one; it costs nothing.
- Automatic capture needs Chromium
- Firefox and Safari can send and receive pasted text, but cannot read the clipboard on their own.
If a session needs to be harder to walk into, the key can be locked with a PIN. That changes the room itself rather than adding a permission check on top of it, so a locked link cannot be opened by someone who has the key but not the PIN — and it does not silently fall back to the unlocked room of the same key.
No install either
It is a web page, so there is nothing to install and nothing to approve. That matters most on the machines where it is not your call: a work laptop with locked-down software installation, a shared or library computer, a Chromebook, or a phone you would rather not add another app to.
If you do want it to feel like an app, it installs as a PWA from the browser's own menu — no store account involved. The install guides cover each platform, and there are native desktop builds and a CLI if you would rather have those.
Is a no-login clipboard safe?
For its intended use — moving text between your own devices — the absence of an account makes it safer rather than less safe, because there is no account to breach and no stored history to leak. The encryption is done in your browser, so nobody watching the network — your Wi-Fi, your ISP — can read your clipboard.
The room address the operator does see is derived through the same 250,000-iteration key stretching, so it cannot be reversed to your key without paying that cost per guess. The threat model gives the arithmetic.
The real risk is the one named above: a short key is short enough to be guessed by someone determined, so it is the wrong tool for a secret that would matter in a year. Use the PIN lock for anything sensitive, and treat an unlocked session the way you would treat a note left on a desk. The source is on GitHub under the MIT licence, and you can run your own relay if you would rather not trust anyone else's.
Common questions
Is there an online clipboard that does not require an account?
Yes. A shared short key can identify a session instead of a signed-in identity, so both devices simply type the same key and are placed in the same room. No email address, password or profile is involved at any point, and the service cannot tell one user from another because it is never given anything that would.
Do I need to install anything?
No. It runs in a browser tab on Windows, macOS, Linux, Android, iOS and ChromeOS. You can optionally install it as a progressive web app from the browser's own menu, which needs no app store and no account, and there are native desktop builds and a command-line tool if you prefer.
Is a clipboard with no login secure?
The text is encrypted in your browser before it is sent, and the server is addressed by a hash of your key rather than the key itself. Having no account removes the two things most often breached — a credential database and stored history. The trade is that the short key is the only thing protecting an unlocked session, so lock it with a PIN for anything sensitive. The threat model is specific about it.
Is it really free, and what is the catch?
Free, with no paid tier and no trial. The honest catch is scope rather than money: file transfers are capped at 5 MB, and automatic clipboard capture needs a Chromium-based browser. It is open source under the MIT licence, so nothing stops you running it yourself.
What happens to my text after I close the tab?
It is gone. The relay holds messages only long enough to forward them and writes nothing to disk, and with no account there is no server-side history attached to you. Anything kept locally lives in your own browser storage and is cleared with it.
