Clusterix Authenticator vs 2FA iAtomos

InnOS Authenticator is a secure two-factor authentication application designed for utmost convenience. Simply scan the QR code once, and it will continuously provide you with unique code combinations for enhanced security, even offline. Switch off 2FA whenever you want. Your digital world, now safer than ever.

FREE FOREVER 2FA iAtomos is free forever. There is no subscription, no advertising and nothing to buy inside the app. Codes follow the open TOTP standard, and the optional cloud copy is encrypted on the phone before upload. You can import accounts from Google Authenticator, Authy, 2FAS and Aegis. About five seconds before a code changes, the app can warn you. 2FA iAtomos generates your two-factor codes on the phone itself. No account, no connection, no tracking. Your 2FA secrets live in a vault encrypted on the device with AES-256-GCM. The key is held by the iOS Keychain. Nothing leaves the phone unless you decide it should. CLOUD BACKUP, NO PASSWORD TO REMEMBER Sign in and your accounts are saved automatically. Every change is encrypted on your device with AES-256-GCM before upload, with a key that lives only in your iCloud Keychain. On your next iPhone or iPad with the same Apple ID, your accounts appear on their own. A green cloud on the home screen tells you everything is saved. The server only ever receives encrypted data. Restoring merges accounts and never deletes what you already have, and an altered copy or a version conflict leaves your local vault untouched. You can switch the backup off at any time and it is deleted from the server. AN INDEPENDENT ENCRYPTED FILE Export a password-protected file whenever you like. It does not depend on the cloud backup or on any account, so you always have a second way back. WHAT IT DOES • Standard 2FA codes (TOTP, RFC 6238) with SHA-1, SHA-256 and SHA-512, 6 or 8 digits • Scan a QR code, import a Google Authenticator export, or type the secret • Face ID or Touch ID lock, with the device passcode as fallback • Favorites, search and a custom order • The service's own period is respected, never stretched to buy time • English, Spanish, Catalan, German, French, Italian, Portuguese, Japanese, Korean, Chinese (Simplified) and Russian BUILT FOR EVERYONE The app follows your iOS accessibility settings rather than fighting them. Larger Text grows the code instead of shrinking it, Increase Contrast switches to a high-contrast palette, Reduce Motion stops the countdown animating, and Bold Text and Smart Invert are honored. With VoiceOver, every code can be read out digit by digit and copied, starred or deleted through rotor actions. Time remaining is available on demand, so nothing interrupts you mid-code. Urgency is never signaled by color alone. WHAT IT DOES NOT DO • No ads • No data selling • No behavioral tracking • No secrets, account names or generated codes in any log or report The optional account lets you sign in with Apple, Google or your email. Those services process account identifiers and diagnostic data, and the privacy policy says exactly which and when. The security model is written down, not implied.
