Digital Legacy Letter
betaThis free digital legacy letter tool lets you write a private message and store account passwords for your loved ones, sealed with AES-256 encryption. Unlock it with a password or split it into family shares — nothing is ever uploaded.
Write a private letter — passwords, accounts, and final words — that your family can open only when the time comes. It is encrypted on your device; nothing is ever uploaded.
How it works
Write
Your final message + account logins and passwords.
Lock on your device
Encrypted with AES-256 right here. Nothing is uploaded to any server.
Choose the keys
Protect it with a password, family shares, or both.
Opened later
When the time comes, family unlocks it with the password or by combining shares.
The clever part: family shares
split into 5 shares — give one to each relative
any 3 unlock it →
2 spare — can be lost
All 5 shares go to 5 people. Any 3 of them — it doesn’t matter which 3 — together open the letter, so no single person can open it alone and up to 2 shares can be lost. The solid vs. dashed boxes above just show one example trio; you pick the numbers (2-of-3, 3-of-5, 4-of-7…).
Private by design. Everything is encrypted and decrypted in your browser. Your passwords are never sent anywhere — not even to us.
You arrange the handoff. A private tool can’t detect when you’ve died, so it can’t auto-release. Share the password or the shares so they only come together when the time comes — tip: give one share to your lawyer or executor.
How to use Digital Legacy Letter
- 1 Write your message and add each account — service, username, password, and notes.
- 2 Choose how family will unlock it: a password, family shares (any 3 of 5, say), or both.
- 3 Download the encrypted .gwtvault file and store it safely; hand out the shares separately.
- 4 When the time comes, your family opens the file here with the password or by combining shares.
Frequently asked questions
Is my letter or my passwords uploaded anywhere?
No. Everything is encrypted and decrypted on your device with AES-256-GCM. The file never leaves your browser, so your passwords are never sent to any server.
How do family shares work?
The key is split into several shares (for example 5) using Shamir Secret Sharing, and a chosen number of them (say any 3) are needed to open the letter. No single person can open it alone, and it still works if a few shares are lost. Tip: give one share to your lawyer or executor.
Can it release automatically when I die?
Not automatically — a private, in-browser tool cannot know when you have died without a server holding your data. Instead you control the handoff: share the password or the family shares so they can only be brought together when the time comes.
What if I lose the password and the shares?
Then the letter cannot be opened — by design, so no one else can read it either. Keep the file and the way to unlock it stored separately and safely.
