2FA Authenticator: OTP Codes

Never get locked out of an account again. AuthenticKey is the 2FA authenticator app built around the one thing other authenticators get wrong: moving to a new iPhone. Generate secure two-factor authentication codes for Google, Microsoft, Apple, Facebook, Instagram, GitHub, Coinbase and 1000+ other services — backed up through your private iCloud and ready the moment you sign in on a new device. WHY AUTHENTICKEY Most authenticator apps trap your 2FA codes on a single device. Lose the phone, factory reset, or upgrade to a new iPhone — and you're locked out of every account, hunting for recovery codes you never saved. AuthenticKey fixes this with end-to-end encrypted iCloud sync. Your codes follow your Apple ID, not your hardware.

Sync uses your private iCloud — Apple can't read your codes and neither can we. We never see, store, or transmit your 2FA secrets in any form. For app improvement and crash diagnostics we collect anonymous usage statistics. Your 2FA secrets are never part of that data and never leave your device unencrypted.
