A fully offline multi-factor authenticator. Your secrets never leave your device — no account, no ads, no tracking. Migrate from Google Authenticator in seconds.
TwoAuth is a clean, secure and fully offline authenticator that generates verification codes for two-factor (2FA) and multi-factor (MFA) authentication — a drop-in replacement for Google Authenticator and Microsoft Authenticator.
WHY TWOAUTH
• Fully offline: no sign-up, no servers, ever
• Keys stay private: secrets are stored only in the local system Keychain and never uploaded
• Zero data collection: no ads, no analytics, no third-party SDKs
• Standards-based: a faithful implementation of RFC 4226 (HOTP) and RFC 6238 (TOTP), compatible with every website, enterprise system and service that supports two-factor or multi-factor authentication
MOVE IN SECONDS
• Scan the "Transfer accounts" QR codes from Google Authenticator to import everything at once
• Add accounts by scanning a website QR code, reading a QR code from your photo library, or entering the secret key manually
BUILT FOR SPEED
• All codes on one screen, refreshed at the same instant
• Codes flash red for the final 5 seconds, with the next code previewed and ready to copy
• Tap a card to copy; pin favorites to the top
• Brand logos for well-known services help you find accounts at a glance, with manual icon override
BACKUP & TRANSFER
• Bulk export as migration QR codes (Google Authenticator compatible)
• Bulk export as a JSON file
• Export any single account as a standard otpauth QR code
THE DETAILS
• Light / dark themes — follow the system or set your own
• English, Simplified Chinese and Traditional Chinese
• SHA1 / SHA256 / SHA512, 6–8 digit codes, custom periods and counters
IMPORTANT
Before deleting an account, disable two-factor authentication on the website or switch to another authenticator first, or you may be locked out.
