Why Your Master Password Matters
Your master password is the only way to unlock your entire vault. It's the only password you'll ever need to remember—but it's also the only thing standing between your data and anyone who wants access.
Because Local Password Vault stores everything offline with zero-knowledge encryption, we never see or store your master password. This means:
- We can't recover it if you forget it
- No one can reset it for you
- It cannot be breached from our servers (we don't have it)
Critical: If you forget your master password, your vault data is permanently inaccessible. There is no recovery option. This is by design—it's what makes your data truly secure.
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:
- Easier to remember than random characters
- Much longer, making them harder to crack
- Easy to type accurately
Example Passphrases
Four random words connected with dashes. Easy to remember, extremely hard to crack.
Another Example
Three words with symbols and a number. More complex but still memorable.
Length Over Complexity
A 20-character passphrase of simple words is far more secure than an 8-character password with symbols. Every additional character exponentially increases the time needed to crack it.
Minimum recommendation: At least 12 characters, but 16-24 is ideal for a master password.
Use Our Built-In Passphrase Generator
Don't want to come up with a passphrase yourself? Local Password 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
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:
- Regenerate until you find one you like
- Customize the number of words (3-6 words)
- Add numbers or symbols between words for extra security
- Copy it to write down before confirming
Tip: Generate a few options and pick the one that creates a mental image or story in your head. "timber-crystal-voyage-anchor" might make you think of a wooden ship with a crystal cargo dropping anchor—that mental picture makes it unforgettable.
Do's and Don'ts
✓ Do This
- Use 4+ random, unrelated words
- Add numbers or symbols between words
- Make it at least 16 characters
- Use something personally meaningful but not guessable
- Write it down and store it safely (physically)
- 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
- Use only numbers or only letters
- Share it with anyone
- Store it in a text file on your computer
Where to Store Your Master Password
Until you've memorized it completely, you need a backup. Here are safe options:
- Write it on paper and store in a fireproof safe or safety deposit box
- Store it with your will or important documents that only trusted family can access
- Split it—write half in one place, half in another
Never store your master password: In a text file, in your email, in cloud notes, in a browser password manager, or anywhere digital that could be hacked.
Changing Your Master Password
You can change your master password at any time from within the app:
- Open Local Password Vault and unlock with your current password
- Go to Settings → Security
- Click Change Master Password
- Enter your current password, then your new password twice
- Click Save
Tip: After changing your master password, create a new backup of your vault. Old backups will still require the old password to restore.
