Opening Seal…
Your memory, sealed.
Signing in tells Seal where your memory is. Only your passphrase and your 24 words open it; Seal's servers never hold the key to your memory.
Seal is invitation-only while it is being tested. If you were invited, sign in with the email address the invitation went to.
You're on the waitlist
Create your vault
Choose a passphrase for this browser. It never leaves this page. Then you will be shown 24 words. They are the only way into your memory from another device, and nobody, including us, can replace them.
Write these down
Not stored by this page and not sent anywhere. Settings shows them again only after your passphrase, on a device that opens your vault. Without one, they cannot be recovered.
On paper. Not in a screenshot, not in a notes app.
Check your paper
Type these four back from what you wrote down, not from the screen. The screen is about to be wrong on purpose.
Show me the words again. Nothing is lost by looking, and this check is exactly why.
Unlock
Welcome back. This browser already holds your sealed vault. The passphrase opens it here and goes nowhere.
Different device, or forgot the passphrase? Use your 24 words.
Open on this device
Your words rebuild the vault here. The passphrase you choose now is this device's lock from then on.
