U2 Secured Vault

U2 Secured Vault is a zero-knowledge password manager. Every password, note, and card is encrypted on your device with a key derived from your master password — so the server stores only unreadable ciphertext and can never see your secrets.

WHY U2 SECURED VAULT • Zero-knowledge by design — encryption and decryption happen entirely on your device. We can't read your data, and neither can anyone who breaches our servers. • Strong cryptography — AES-256-GCM for your items, Argon2id to harden your master password, X25519 for secure sharing. • Built-in strong password generator — create unique, high-entropy passwords in one tap. • Everything in one place — logins, secure notes, credit cards, Wi-Fi, and more, organized in folders. • Two-factor login — protect your account with TOTP and trusted-device verification. • Secure sharing — send an item through an encrypted, expiring link. Set an expiry, add a passphrase, or burn it after one view. • Fast and private — a clean, focused interface with no ads and no tracking.

HOW IT WORKS Your master password never leaves your device. It derives the key that encrypts your vault, and only a verifier — never the key itself — is sent to the server. Lose the connection, switch devices, or face a server breach: your secrets stay sealed.

WHO IT'S FOR Anyone who wants a password manager that genuinely can't read their passwords — individuals, families, and teams that take privacy seriously.
