SikkerLink is a new, free tool for the moment you need to hand someone a password, API key, or any secret and don't want it living in a chat message or an email forever. Paste the secret, get a link, send it. The link opens once, then it's gone.

Encrypted in your browser

The secret is encrypted in your browser before it ever leaves the page, with a key only the link carries. SikkerKey's servers store an unreadable blob and nothing else, so no one on our side can read what you sent.

One view, then it self-destructs

The first time the recipient opens the link, the secret is shown and immediately destroyed. Reload the page and there's nothing left. You also choose how long a link stays alive, from one hour to a day, after which it expires on its own.

Keep the passphrase in the link, or split it

By default the key travels inside the link, so anyone you send it to can open it once. Prefer to split it? Turn that off and you get the passphrase to share over a separate channel, so the link on its own is useless.

No account, nothing to install

There's no sign-up and nothing to set up. Open sikkerlink.com, paste, and share. It's free.
