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.
