Never get locked out of your accounts. Authenticator creates secure 2FA codes for every account, keeps them encrypted on your device and backs them up to your private iCloud, so a lost, broken or new iPhone is never a problem. WHY PEOPLE SWITCH • Encrypted iCloud backup and one-tap restore on a new iPhone (Pro) • Codes work offline: no signal or Wi-Fi needed • Face ID and Touch ID keep your codes private • Move accounts over in one step from Google Authenticator, other apps or a file • Home Screen widget shows codes without opening the app BACKUP AND RESTORE Your 2FA secrets are encrypted before they leave your device and are stored in your own iCloud. Sign in on a new iPhone and every account comes back. Prefer to keep it yourself? Export an encrypted backup file. END-TO-END ENCRYPTION Codes are encrypted on your device using your iCloud Keychain. No one but you can read them. SET UP IN SECONDS Scan a QR code or enter the setup key. No account, no email, no signup.
