Creating Your Master Password

Why Your Master Password Matters

Your master password is the single key that unlocks your entire vault—including all the important information you're preserving for your family. It's the only password you'll ever need to remember, but it's also what your loved ones will need when the time comes.

Because Local Legacy Vault stores everything offline with zero-knowledge encryption, we never see or store your master password. This means:

Critical: If you forget your master password and haven't stored it somewhere safe, your vault data is permanently inaccessible. More importantly, your family won't be able to access the information you've prepared for them.

What Makes a Strong Master Password

A good master password is both strong (hard to guess or crack) and memorable (you won't forget it). Here's how to create one:

Use a Passphrase

Instead of a complex string of random characters, use a passphrase—a series of random words strung together. Passphrases are:

Example Passphrases

garden-sunset-bicycle-memory

Four random words connected with dashes. Easy to remember, extremely hard to crack.

Another Example

Grandma!Kitchen#Roses1987

Words that mean something to you, with symbols and a year. Personal but not guessable.

Use Our Built-In Passphrase Generator

Don't want to come up with a passphrase yourself? Local Legacy Vault includes a built-in passphrase generator that creates strong, memorable passphrases for you.

When you first set up the app or change your master password, you'll see a "Generate Passphrase" button. Click it to instantly create a secure passphrase like:

Generated Passphrase Example

meadow-compass-harbor-willow

Four random words that are easy to remember but impossible to guess. The generator uses a dictionary of common English words to create combinations that are both secure and memorable.

You can:

Tip: Generate a few options and pick the one that creates a mental image or story. "meadow-compass-harbor-willow" might remind you of a peaceful journey—that mental picture makes it unforgettable. Write it down and store it with your will so your family can access it when needed.

Do's and Don'ts

✓ Do This

  • Use 4+ random, unrelated words
  • Add numbers or symbols between words
  • Make it at least 16 characters
  • Write it down and store it with your will
  • Tell a trusted family member where it's stored
  • Practice typing it until it's muscle memory

✗ Don't Do This

  • Use your name, birthday, or pet's name
  • Use common phrases like "iloveyou"
  • Reuse a password from another account
  • Keep it only in your head
  • Share it casually or store it insecurely
  • Forget to tell family where to find it

Where to Store Your Master Password

Your master password needs to be accessible to your family after you're gone. Here are safe options:

Important: Make sure at least one trusted person knows that this password exists and where to find it. The best-prepared vault is useless if no one can open it.

Telling Your Family

You don't need to share your password now, but your family should know:

  1. That Local Legacy Vault exists on your computer
  2. What kind of information it contains
  3. Where to find the master password when needed
  4. That they should NOT try to guess—they only get a few attempts

Never store your master password: In a text file on your computer, in your email, in cloud notes, or anywhere that could be hacked or lost with your computer.
