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.
KEY FEATURES
• One-tap setup — scan any 2FA QR code in seconds
• Encrypted iCloud sync across iPhone and iPad
• Apple Watch app — generate codes from your wrist (Premium)
• Home Screen widget for instant code access (Premium)
• Face ID, Touch ID and passcode lock for the app itself
• Auto-clearing clipboard — copied codes wipe after 30 seconds
• Works offline — TOTP and HOTP codes generate without internet
• Supports SHA-1, SHA-256 and SHA-512 algorithms
• Full RFC 6238 (TOTP) and RFC 4226 (HOTP) standard compliance
• 11 languages: English, Spanish, French, German, Italian, Portuguese, Dutch, Korean, Japanese, Norwegian, Swedish
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.
WORKS WITH 1000+ SERVICES
Google · Microsoft · Apple · Amazon · Facebook · Instagram · X (Twitter) · Snapchat · TikTok · Discord · GitHub · Slack · Zoom · Dropbox · Coinbase · Binance · Kraken · KuCoin · Crypto.com · PayPal · Stripe · AWS · Azure · Salesforce · Okta · Duo · Cloudflare · Twitch · PlayStation · Xbox · Steam · Epic Games · LinkedIn · Reddit · Shopify · Notion · 1Password · LastPass · Bitwarden · ProtonMail · Tutanota · Fastmail — and any service supporting standard TOTP or HOTP.
PERFECT FOR
→ Crypto traders securing Coinbase, Binance and Kraken accounts
→ Developers managing AWS, GitHub and Cloudflare access
→ Remote teams using Microsoft 365, Google Workspace and Slack
→ Anyone who's lost 2FA codes during an iPhone upgrade
→ Privacy-conscious users who want their secrets to stay on Apple's hardware
HOW WE PROTECT YOUR DATA
Your 2FA secrets are encrypted on your device with AES-256-GCM and stored in the iOS Keychain. 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.
