2FA Authenticator vs BLE Sniffer

Secure your accounts with Autheris — a privacy-first two-factor authentication (2FA) app for iPhone, iPad, Mac and Apple Watch. Autheris generates the time-based one-time passwords (TOTP) that protect your most important accounts, and keeps the secrets behind them on your device. No account, no sign-up, no ads. NOW ON APPLE WATCH • One Code at a Time — Your codes on your wrist, each with a live countdown. Turn the Digital Crown to move between them. • Read-Only by Design — There is no copy, no editing and no settings on the watch. Your iPhone stays the one place codes are managed. • Works Without Your iPhone — Codes are generated on the watch itself, so they keep counting down with your phone out of reach or switched off. KEY FEATURES • One-Tap Codes — Copy a code with a single tap. The clipboard clears itself after 60 seconds. • Pin and Reorder — Pin the codes you use most to the top, and drag the rest into whatever order suits you. • Recently Deleted — Delete a code by mistake? It stays on your device for 7 days, ready to restore. • QR Scanning — Add an account by scanning a QR code, or choose a screenshot from your photo library. • Time-Based and Counter-Based Codes — TOTP for almost every service, and HOTP for the ones that hand you a counter instead, each with SHA-1, SHA-256 or SHA-512 and 6 to 10 digits. If a service rejects your codes, the algorithm is editable per account. • Import — Bring your token generator accounts across from Google Authenticator, Aegis, andOTP or 2FAS. • Search — Find any account instantly, however long your list gets. • Issuer Icons — Familiar brand marks so you can spot an account at a glance. • Countdown Ring — A clear, colour-customisable ring shows how long each verification code has left. PRIVACY AND SECURITY • Face ID / Touch ID Lock — Locks when opened, and again after 30 seconds away. • Blurred When Backgrounded — Content blurs when you switch apps, and your codes are hidden in the app switcher. • Protected While Recording — Codes are covered whenever your screen is being recorded or mirrored. • Secrets Stay on Your Device — Codes and setup keys are kept in your device's Keychain and never leave it unless you export them or turn on iCloud Sync. • Encrypted Backups — Save an AES-256-GCM encrypted backup protected by a password only you know. • Optional iCloud Sync — Off by default. When you enable it, your secrets are end-to-end encrypted by CloudKit, and the developer cannot read them. • No Account, No Tracking — Nothing to sign up for, no analytics, no advertising. Autheris is open source. Install Autheris, add an account, and keep your second factor — and your 2-step login — under your own control.

BLE Sniffer turns your iPhone into a passive Bluetooth Low Energy scanner. See the BLE devices broadcasting around you, log what they're advertising, and use a proximity radar to gauge how close they are — all without connecting to anything. Think of it as a "sniff raw" mode for the Bluetooth Low Energy spectrum: capture the advertisements in the air, filter nothing, analyze offline. Whether you're mapping the BLE devices in your own home, auditing your gear, or reverse-engineering your own hardware, BLE Sniffer shows you what's broadcasting nearby. WHAT IT DOES Live device scanning See a real-time list of the nearby BLE devices that are advertising — name, identifier, signal strength (RSSI), manufacturer, service UUIDs, advertisement count, and first/last-seen times. Sort by signal, activity, name, or recency. Device categorization (heuristic) A built-in lookup of the complete Bluetooth SIG manufacturer registry — 4,000+ vendor IDs — plus vendor and name heuristics attaches a visual badge to some devices to help you triage a long list — for example dev boards, smart-home gear, and devices whose manufacturer ID or advertised name matches known camera vendors. These are best-effort guesses based on what a device broadcasts, not confirmed identifications. Proximity radar & "Geiger" mode A radar view plots advertising devices on concentric rings by signal strength. Pick one device and switch to single-device mode: a big live RSSI readout with color-coded background plus audio and haptic feedback that speeds up as the signal gets stronger — walk around and home in on it like a metal detector. Sessions & baseline diffing Save a scan as a named session. Capture a baseline in one location, scan another, and diff the two — see which advertising devices appear in the new scan but not the baseline. A quick way to narrow a long list down to what changed. Full CSV export Export any session or live scan as CSV — one row per advertisement, with timestamps, identifiers, RSSI, manufacturer IDs, service UUIDs, TX power, and raw advertisement bytes. Share it anywhere via the system share sheet for offline analysis. Optional device inspection For devices you own, opt in to connect and browse the GATT service tree — read manufacturer, model, and firmware info and explore characteristics. Connections are always explicit and per-device; the app never auto-connects. PRIVACY-FIRST BY DESIGN • Passive by default — it listens, it doesn't transmit or pair • No ads, no in-app purchases, no subscriptions • No telemetry, no accounts, no cloud — your data stays on your device • Everything is logged locally and exported only when you choose GREAT FOR • Mapping and auditing the BLE devices broadcasting in your own home or office • Hardware hackers, makers, and security researchers • Anyone curious about the invisible radio traffic around them PERMISSIONS BLE Sniffer asks only for Bluetooth access, which it uses to listen for nearby device advertisements. It does not pair, transmit, or request your location. Each device appears under an app-scoped identifier assigned by iOS — no hardware addresses are exposed. NOTE BLE Sniffer is a passive observation tool for the Bluetooth Low Energy spectrum. It detects Bluetooth Low Energy advertisements only — it is not a hidden-camera or surveillance detector and cannot find devices that don't broadcast BLE (including many cameras, and anything using Bluetooth Classic, Wi-Fi, or cellular). RSSI indicates rough proximity (distance), not direction, and device categories are heuristic guesses, not guarantees. Please use it responsibly and legally.
