  • Password manager master key dies with you
  • Last words never reach loved ones
  • Existing "encrypted" services can still read your data
With WillMessage
  • True zero-knowledge encryption for your sensitive data

How It Works

Three simple steps. Complete zero-knowledge security.

01

Create Your Vault

Add messages, passwords, crypto keys, or documents. Everything stays on your device until encrypted. Choose how the decryption key will be created and delivered.

02

Encrypt & Timestamp

Your vault encrypts in your browser using AES-256 encryption. A digital fingerprint is registered on Bitcoin as proof your vault existed at this moment and has not been modified.

03

Automatic Delivery

Set your check-in schedule. If you stop responding, the system triggers delivery. Your beneficiary receives the encrypted vault via email, SMS, and postal letter. Only the correct key unlocks it.

Choose Your Vault Type

All zero-knowledge. Choose the level of security that fits your needs.

Default

Passphrase

You create a passphrase that encrypts your vault. Download a document with the passphrase and deliver it to your beneficiary yourself. Once check-ins stop, the system triggers delivery of the encrypted vault. Your beneficiary enters the passphrase to unlock it in the browser.

Create a strong passphrase and deliver it yourself

  • You create the passphrase
  • You deliver it
  • We deliver the encrypted vault
  • Decrypted in beneficiary browser

Best for: General Use, Corporate Succession

Alternative

Shared Memory

Security questions only you and your beneficiary can answer. The encryption key is derived from the answers. We only store the questions, never the answers. Once check-ins stop, the system sends the encrypted vault with the questions. Correct answers unlock it in the beneficiary browser.

"What year did we first meet?" "What was our first pet's name?"

  • Encryption key derived from answers
  • Beneficiary needs nothing beforehand
  • We only store questions, never answers
  • Decrypted in beneficiary browser

Best for: Family, Partners, Close Friends

Pro Plan

Smart Contract

Maximum security through separation. Your encryption key is stored in a blockchain smart contract. When check-ins stop, an external oracle sends the key independently. WillMessage sends the encrypted vault separately. Two different sources, no single party has complete access.

Oracle sends the key. WillMessage sends the vault.

  • Key stored in smart contract
  • Key delivered by oracle (not us)
  • Vault delivered by WillMessage
  • 2 independent sources, maximum security
  • Decrypted in beneficiary browser

Best for: Crypto Holders, Security Professionals

The Delivery Process

No accidental triggers. Multiple safeguards before activation.

Step 1

Set & Manage Your Check-in

When creating your vault, you choose your check-in interval: from 30 days to 365 days. You can modify it later from your dashboard. To confirm you're active, log in and click to reset the timer. Do it proactively or when you receive a reminder.

Step 2

We Try to Reach You

If you miss the check-in, we send you reminders via email and SMS. First a friendly reminder, then more urgent ones. Multiple attempts over several days. We exhaust all options before taking any action. No false alarms.

Step 3

The Switch Activates

Only after all contact attempts fail does the system trigger. Your encrypted vault is delivered to your beneficiary via email, SMS, and letter. Pro plan adds phone call and registered letter for maximum reliability.

Your beneficiary receives the encrypted vault. Without the decryption key, it's just meaningless data.

Zero-Knowledge Means We Mathematically Cannot Read Your Data

Your encryption key never touches our servers. Even if we're hacked, attackers get useless encrypted blobs. This isn't "trust us" encryption. This is verifiable, auditable, cryptographic certainty.

Frequently Asked Questions

Everything you need to know about WillMessage.

WillMessage is a cryptographically secure dead man's switch for your digital life. Your digital contingency plan with true zero-knowledge encryption. Store critical information - passwords, crypto keys, documents, last words - that's automatically released to your beneficiaries only when needed. Bitcoin-timestamped and verifiable.
No. Your encryption key never touches our servers, whether derived from shared answers, a passphrase, or stored in a blockchain contract. We store encrypted blobs that are useless without the key.
With Passphrase mode, you deliver the passphrase document yourself, so remind your beneficiary where to find it. With Shared Memory mode, choose questions with answers that are truly unforgettable between you both. With Smart Contract mode, there's nothing to remember: the key is delivered automatically by an external oracle.
Without the encrypted vault, the key is useless. We only send the vault to the configured beneficiary when the switch activates. We never execute manually, never deliver on request. Even if someone has the decryption key, they cannot get the vault from us.
In the unlikely event we ever discontinue the service, we would notify all users at least one year in advance. Your encrypted vault is always exportable. The encryption is standard AES-256-GCM, any implementation can decrypt with the right key.
Both encryption and decryption happen entirely in your browser using Web Crypto API. We use AES-256-GCM for encryption and SHA-256 for hashing. Our crypto library will be open source. We are currently finalizing the repositories and will make them public when the product launches.
Text, images, PDFs, audio, and video files. Optimized for passwords, crypto keys, critical documents, and messages. Not designed for large media archives. Executables are not allowed for security reasons.
Bitcoin for timestamping all vaults via OpenTimestamps, proving your data existed at a specific moment and has not been modified. Smart Contract mode uses EVM-compatible networks like Polygon or Ethereum, with Chainlink oracles to deliver the key.
WillMessage is a secure storage and notification service, not a legal will. Consult a lawyer for legally binding estate planning.
