Cue Vault

Cue Vault generates unique, strong passwords for every service you use without ever storing them. Instead of saving passwords to a vault that can be breached, it derives them on the fly using a 4-digit PIN, a passphrase, and a short 4-letter cue you assign to each service. Same inputs, same password, every time. No database to hack. No cloud to compromise. How it works - Set up a 4-digit PIN and a memorable passphrase - Add services with a unique 4-letter cue (e.g., "gmai" for Gmail) - Tap a service to instantly generate and copy its password - Your PIN and passphrase are secured with Face ID / Touch ID Why it's different - Zero password storage — passwords are computed, not saved - Works completely offline — no servers, no accounts, no sync - Biometric-protected credentials stored in your device's secure Keychain - With manual fallback you can reconstruct any password by hand using the built-in guide, even without the app - Beautiful dark and light themes with smooth animations Security by design Your PIN and passphrase never leave your device. Service data is encrypted locally with MMKV. There's no cloud backend, no analytics, and no network requests. If your phone is lost, your passwords can't be extracted without biometric authentication. One PIN. One passphrase. Unlimited unique passwords.
