## What is 2FA Authenticator?

Keep your two-factor authentication codes together with Auth., an offline authenticator for iPhone and iPad. Generate time-based one-time passwords (TOTP), add compatible accounts with a QR code and tap to copy a verification code when you sign in.

START WITH 3 FREE ACCOUNTS
Basic includes up to three accounts, QR scanning, saved QR image import, manual key entry, compatible account imports, search, favorites, app lock and account exports. No Auth. sign-up is required. There are no ads.

CODES READY OFFLINE
Get six-digit codes that refresh every 30 seconds, with a clear countdown. Once you add an account, code generation works without an internet connection. Protect access with Face ID, Touch ID or your device passcode. Your vault is encrypted on your device. Usage analytics and crash reporting are optional; account names, setup keys and codes are not sent to analytics providers.

OPTIONAL WEEKLY PREMIUM
Auth. Premium adds unlimited accounts, custom categories and creation of encrypted local backup snapshots. It is an auto-renewing weekly subscription with no free trial. Your local price appears in the app before purchase. Payment is charged to your Apple Account at confirmation. Cancel at least 24 hours before the current period ends to stop renewal. Manage or cancel in your Apple Account settings. Restore eligible purchases with the same Apple Account.

After Premium expires, existing codes, exports and recovery from saved local snapshots remain available. Adding accounts beyond the Basic limit, creating custom categories and creating new snapshots require Premium.

PLAN FOR RECOVERY
Encrypted snapshots stay in this installation and depend on its device-bound key. They are not cloud backups. Transfer your accounts before deleting the app or changing phones, and keep each service’s recovery codes separately. JSON exports are unencrypted and contain secret keys: store them securely. We cannot recover lost secrets. Restoring a subscription does not restore your vault or accounts.

COMPATIBILITY AND LANGUAGE
Supports SHA-1 TOTP with six digits and a 30-second period. Unsupported formats are rejected. Auth. does not replace SMS verification or provider-specific push approvals. Requires iOS 17 or later. Purchases and purchase restoration need an internet connection. The app interface is currently in English.
