Secure passwordsAll in one place
Store passwords, secure notes, and credit cards with zero-knowledge encryption.
End-to-end encryption
Secured with AES-256-GCM encryption, the industry standard for protecting sensitive data.
Zero-knowledge
Only you can see your encrypted credentials. Master passwords and encryption keys remain in your control.
Password generator
Create strong, unique passwords instantly with built-in tools for every account.
Advanced activity log
Every sign-in, item change, and trusted device is recorded in a single audit trail — so unusual access can be identified and reviewed with clarity. Built for teams and individuals who need continuous visibility into vault activity without sacrificing encryption or control.
Security by design
Vault is built outside the browser autofill layer, so your credentials are never exposed to extensions or session-level browser risks. End-to-end encryption and a zero-knowledge architecture ensure only you can unlock your data — a deliberate design that prioritizes protection over convenience.
Frequently
asked questions
Vault items are encrypted on your device with AES-256-GCM before they are stored or synced. Encryption keys are derived from your master password, which is never stored in a recoverable form. Only you can unlock passwords, secure notes, and credit cards.
It means Vault App never has the material required to decrypt your vault. Encryption happens locally; the service stores ciphertext. Vault contents cannot be viewed, accessed, or recovered by anyone else — including Vault App.
Vault App stays out of the browser autofill layer on purpose. Extensions sit in a privileged position across every tab and are a common phishing and malware target. Unlocking in the app and copying what you need keeps retrieval intentional and shrinks that attack surface.
The master password is never stored or transmitted in a recoverable form, so it cannot be reset or recovered. If it is lost, access to the encrypted vault cannot be restored. That tradeoff is what keeps vault contents unreadably sealed. If you have a paid plan and cannot sign in, you can still cancel billing through Stripe receipt or invoice emails, or email support@vault0.app for billing cancellation only. Subscription billing is separate from vault encryption, so canceling in Stripe does not require unlocking your vault — and it does not restore vault access.
Passwords and usernames, website addresses, secure notes, and credit cards — including cardholder name, number, expiration, and CVV. Everything uses the same end-to-end encryption and zero-knowledge architecture.
Productized sharing usually requires a server that can mediate or read secrets. That conflicts with a vault Vault App cannot decrypt. Sharing is left out so exclusive control over credentials stays intact.
