U2 Secured Password Vault

Read full description

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

OffMemory is a fully encrypted diary — your words stay on this device. Every note, title, photo and drawing is locked with AES-256, and the password is derived with Argon2id, so guessing it offline is expensive. No cloud, no servers, no ads. It opens and you write Layered materials, a restrained type scale, a hairline border instead of shadows, and light or dark following the system. Every touch target was audited for size and contrast — a journal that does not compete for attention: writing first, features second. Three things worth calling out 1. Second Vault: set a second, decoy password. Unlocking with it opens a separate space where your real journal is not visible — separate database, separate keys, separate media folders, not merely a hidden entrance. 2. Apple Watch: capture from your wrist, entries wait in a sync queue so nothing is lost offline, and you can lock the phone from your wrist. No new permissions, and the watch never keeps note text. 3. On-device summaries on Apple Intelligence devices: summarise, suggest a title or reflect. Nothing leaves the device. Key features 1. Password protection with Face ID; the app locks itself when it leaves the foreground 2. Recovery code: write it down once and your notes stay readable even if you forget the password 3. Per-note lock: one entry behind its own Face ID check, separate from the app lock 4. Time Capsule: a letter to your future self, sealed until the day you choose 5. Full Markdown toolbar with inline sizes and colours, folders, tags, favourites, moods and a writing calendar 6. Event date: date an entry by when it happened, separately from when you wrote it 7. Insights: a year of writing as a heat map, with streaks, active days and average length 8. Year in Review: a year on one page; the optional share card carries statistics only, never note text 9. Optional Spotlight index — titles only, off by default, never locked notes, never note bodies 10. Home-screen widget and Lock Screen control (iOS 18+) 11. Export to PDF, Obsidian-ready Markdown or mood CSV; an encrypted backup restores on a new iPhone Download free — your first three entries are free to write; a one-time purchase then unlocks unlimited writing, forever. iPhone, iPad, Apple Watch, 15 languages.
