App Description
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.

• Apple Watch app — generate codes from your wrist (Premium)

• Face ID, Touch ID and passcode lock for the app itself

MOVE TO A NEW IPHONE WITHOUT LOSING ACCESS
Sign into iCloud on your new device, open AuthenticKey, and every account is exactly where you left it. No screenshots of recovery codes. No 30-minute account recovery flows. No emails to support teams. Migration that actually works.
