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.
V4ult is a password manager developed by Byt3tech LLC, available on iOS, Android and web, with real-time encrypted sync across devices.
Its architecture follows the zero-knowledge principle: the master password never leaves the user's device. Instead, a key is derived locally using PBKDF2-HMAC-SHA256 with 600,000 iterations, and that key wraps the vault's actual symmetric key. Vault content (passwords, OTP codes, cards, secure notes and identities) is encrypted field-by-field with AES-256 in GCM mode before being sent to V4ult's servers, which only ever receive ciphertext.
Sync functions run on Cloud Functions hosted in the Madrid, EU region (europe-southwest1). V4ult also offers local biometric unlock (Face ID, Touch ID, Android biometrics) to quickly access a session already unlocked with the master password.
As of this publication, V4ult does not have a published independent security audit or formal certifications (ISO 27001, SOC 2, etc.). This page will be updated if that changes.

Frequently asked questions
What is V4ult?
V4ult is a password manager with a zero-knowledge architecture available on iOS, Android and web. It lets you store passwords, OTP codes, cards, identities and secure notes, encrypted on-device before syncing.
Can V4ult read my master password or my data?
No. The master password is processed locally and never transmitted in plaintext. Vault content is encrypted on-device with AES-256-GCM before being sent, so V4ult's servers only ever store encrypted data.
Where does V4ult's sync infrastructure run?
V4ult's sync Cloud Functions run in the Madrid, EU region (europe-southwest1).
Does V4ult have an independent security audit?
No, as of today V4ult has not published any independent security audit or formal certification. This page will be updated if that changes.
