U2 Secured Password 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 PASSWORD 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. • Breach monitoring — your saved passwords are checked against known breach corpora, and anything exposed is flagged on the item and in Alerts, with the number of breaches it appears in. The check never sends your passwords anywhere. • Biometric unlock — open your vault with Face ID or Touch ID instead of retyping your master password. • 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. • Multiple workspaces — keep personal and team vaults separate, and move between them without signing out. • English and French — the app follows your device language, and you can change it any time from the sign-in screen or in Settings. • 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. The key travels in the link itself, so we never hold it. • 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. Start free. Your vault, your key, your control. Privacy Policy: https://u2secured.com/privacy Terms of Use: https://u2secured.com/terms
