About this app

MattaVault is a secure digital legacy vault that keeps your passwords,
documents, and sensitive information protected with military-grade
encryption and safely shared with the people who matter most.

Whether you're storing login credentials, credit cards, identity
documents, or secure notes, MattaVault encrypts everything on your
device before it ever reaches the cloud. Only you hold the key.

ZERO-KNOWLEDGE ENCRYPTION
MattaVault uses a two-layer security model. Your Firebase account
password controls access to your account. Your master password
encrypts your vault using Argon2id key derivation and
XChaCha20-Poly1305 authenticated encryption. Even MattaVault
cannot see your data ever.

EVERYTHING IN ONE PLACE!!

Store and organise all your sensitive data in one secure vault:

• Login credentials (username, password, website)
• Credit and debit cards
• Identity documents
• Secure notes
• SSH keys
• TOTP authenticator codes (2FA backup)
• File attachments (PDFs, images, documents)

Organise entries with folders, categories, and tags. Search and
filter instantly across your entire vault.

BUILT-IN PASSWORD GENERATOR
Generate strong, unique passwords and usernames directly inside
the app:

• Password generator—choose length (5–128 chars), uppercase,
lowercase, numbers, symbols, and avoid ambiguous characters
• Passphrase generator—EFF wordlist based, configurable word
count and separator
• Username generator—random words, plus-addressed email,
catch-all email
• All generation uses a cryptographically secure random number
generator (no predictable patterns)

FAMILY SHARING & VAULT SHARE!!!
• Vault Share—share individual passwords with up to 3 people
(Free and Individual plans)
• Family Vault—share credentials across up to 6 family members.
with role-based permissions (Family plan)
• View-only or edit access per recipient

EMERGENCY ACCESS
Prepare for the unexpected. Grant trusted contacts emergency
access to your vault with a configurable waiting period
(immediately, 24 hours, or 48 hours). You are notified of any
request and can deny it before the waiting period expires.

VAULT HEALTH & SECURITY
Stay on top of your security posture:

• Exposed passwords—checks against the Have I Been Pwned
database (k-anonymity model, your password never leaves
your device)

• Health score (0–100) with actionable recommendations
