V4ult Academy

Verified guides on encryption, authentication and password management, and how V4ult implements them.

• AES-256

  AES-256 is a symmetric encryption algorithm standardized by NIST that uses 256-bit keys. It's one of the most widely used and audited block ciphers in the world.

• Biometric Authentication

  Biometric authentication uses a physical trait — a fingerprint or face — to verify a user, usually processed and matched locally on the device rather than sent anywhere.

• Identification cards in V4ult

  V4ult lets you store identification documents (ID cards, driver's license, etc.) encrypted in the same vault as your passwords, with the same on-device AES-256-GCM encryption.

• Importing passwords into V4ult

  V4ult can import credentials from a CSV file exported by another password manager or browser, with automatic column detection for Chrome, Bitwarden, LastPass and KeePass, and manual mapping for anything else.

• Migrating from Bitwarden to V4ult

  Export your vault from Bitwarden as an unencrypted CSV file, then import it into V4ult — V4ult recognizes Bitwarden's export format automatically, though only logins transfer, not TOTP secrets, cards or notes.

• Migrating from Chrome's password manager to V4ult

  Export your saved passwords from Chrome as a CSV file, then import them into V4ult — V4ult recognizes Chrome's export format automatically.

• Migrating from KeePass to V4ult

  Export your database from KeePass as a CSV file, then import it into V4ult — V4ult recognizes KeePass's export format automatically.

• Migrating from LastPass to V4ult

  Export your vault from LastPass as a CSV file, then import it into V4ult — V4ult recognizes LastPass's export format automatically.

• OTP Codes (TOTP)

  An OTP (One-Time Password) code is a numeric code used only once, valid for a short time window, used as a second authentication factor alongside a password.

• PBKDF2

  PBKDF2 (Password-Based Key Derivation Function 2) turns a password into a cryptographic key by repeatedly hashing it, so that guessing the password by brute force takes deliberately longer.

• Passkeys

  Passkeys are WebAuthn-based credentials that replace passwords: they use a cryptographic key pair instead of a shared secret, and can sync across devices.

• Passwords

  A password is a secret string of characters used to verify a user's identity. It remains the most widespread authentication method, but also one of the most vulnerable when reused or weak.

• QR codes in V4ult

  V4ult lets you store QR codes in the same encrypted vault as your passwords, so you can keep and reuse them (Wi-Fi credentials, one-off links, etc.) without a separate app.

• Secure notes in V4ult

  V4ult's secure notes let you store free-form text (recovery keys, security answers, sensitive information) encrypted with the same AES-256-GCM standard as the rest of the vault.

• V4ult

  V4ult is a password manager with a zero-knowledge architecture: it encrypts your passwords, OTP codes, cards and notes on your own device before syncing, so V4ult itself can never read your master password or your vault's content.

• Vault

  A vault is the encrypted container where a password manager stores all of a user's items: passwords, OTP codes, cards, identities and notes. It can only be opened with the user's master password.

• Virtual credit cards in V4ult

  V4ult lets you store virtual credit cards encrypted in the same vault as your passwords, with the same on-device AES-256-GCM encryption.

• WebAuthn

  WebAuthn (Web Authentication) is a W3C standard that lets web applications authenticate users using public-key cryptography instead of passwords, and is the technical basis of passkeys.

• Zero-Knowledge

  Zero-knowledge is an architecture in which the service provider never has access to the user's master password or plaintext data: all encryption and decryption happens on the user's own device.
