The things you can't afford to lose.
Six situations people use Lastnote for. Find the one that sounds like your life — then open it for a sentence more.
For a partner who isn't tech-savvy Give them access to your passwords and accounts — without trusting it all to one device that could be lost or hacked.
You trust your partner completely, but not the unlocked laptop or the reused passwords. With Lastnote you hand them just one piece of the key — useless on its own. Even if their device is stolen, an attacker has a single piece, and your vault only opens when several are brought together.
For the life you leave behind Make sure your family can reach your photos, accounts, and last wishes — without months of probate.
Seal a vault with what your family will need — accounts, a financial summary, letters to the people you love. Give one piece to each of a few trusted people. While you're here, nothing happens. When you're not, enough of them come together and the vault opens — at their own pace, on their own devices.
For your highest-stakes accounts When everything living on one phone isn't safe enough for what matters most.
Most "two-factor" is really one — your phone holds your authenticator, your codes, your logins. For everyday accounts that's fine. For the handful that can never leak — a crypto seed, a master login, last wishes — Lastnote needs several keys that can't all live on the same device, or even with the same person.
For data AI can't touch Keep your irreplaceable files out of reach of an agent that could delete or leak them.
AI agents now read your files and act on your behalf — and a bad prompt or a wrong move can wipe out things you can't get back. Seal those things into a vault locked with a key the agent has never seen and can't assemble. Full access to your day-to-day life; zero access to your irreplaceable archive — by maths, not by a setting you have to trust.
For your crypto seed phrase A backup no one can steal alone — and you can't lose.
The single paper with your seed words is the most fragile thing in self-custody: lose it and the wallet's gone; have it stolen and it drains in minutes. Split it across five places with any three needed to restore — three cities, a lawyer, a bank box. Lose two and you're still fine. Have one or two stolen and the wallet stays untouchable.
For a startup's critical logins Your most important company accounts, openable only when enough of the team agree.
One founder has the AWS root password, another the Stripe login, the CTO the domain registrar. If any one drops off, the company has a problem. Seal the critical handful and split access across the founding team plus a trusted advisor — any three of five can open it. One person leaving doesn't break access; two insiders acting alone can't get in either.
The next step takes five minutes.
Seal your first vault — your files, your people, your keys. It takes about five minutes, and nothing leaves your device that we could ever read.
