MattaVault

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)

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.
