## What is Sentinel?

Sentinel is a modern authenticator that does more than spit out 6-digit codes. It scores how secure your digital life is, then guides you through enabling 2FA on every account that matters — email, social, banking, crypto, and developer tools.

— SECURITY HEALTH SCORE
Get a single 0–100 score, broken down across six dimensions: 2FA coverage, factor strength, recovery readiness, breach exposure, secret hygiene, and app security. Top recommendations are ranked by impact × ease, so you always know what to fix first.

— GUIDED 2FA WIZARD
A curated catalog of 80+ services — Google, Microsoft, GitHub, Apple, Facebook, Instagram, X, Binance, Coinbase, Stripe, AWS, 1Password, Bitwarden and more — with step-by-step setup, deep links to each security page, and quick QR scanning back into Sentinel.

— ENCRYPTED VAULT
TOTP, HOTP, and Steam Guard codes generated on device, never sent to any server. Secrets live in the iOS Keychain protected by Face ID / Touch ID. Optional 6-digit app passcode as a fallback.

— RECOVERY YOU CAN ACTUALLY USE
12-word BIP-39 recovery phrase. Encrypted .sentinelvault backup with a passphrase you choose — works in iCloud Drive, Files, AirDrop, anywhere. No vendor lock-in.

— BREACH MONITORING
Watch the emails you care about against the Have I Been Pwned database. Sentinel hashes locally and queries via k-anonymity so the plaintext never leaves your device. Weekly background refresh + on-demand checks.

— PRIVACY-FIRST
Zero-knowledge by design. iCloud sync (Pro) encrypts every record on-device with AES-256-GCM keyed by your recovery phrase — Apple cannot read it. No ads. No tracking SDKs. Open-source crypto core.

— HOME & LOCK SCREEN WIDGETS
Glance the next code from your favorite account, or a countdown without revealing the code on a Lock Screen widget. Tap to launch the app for the full code.

— iPAD-NATIVE
Sidebar + detail layout, smooth Dynamic Type, full Dark Mode and tinted icons.

— PRO (OPTIONAL)
Free up to 10 accounts. Unlock unlimited accounts, end-to-end encrypted iCloud sync across iPhone / iPad / Mac, weekly breach monitoring, family sharing for 5 members, and the full guided wizard with monthly, yearly, or lifetime plans.

iOS 17+. No login required.
