Link Auth
2FA codes and secure transfer
Free · Designed for iPad. Not verified for macOS.
Link Auth is a focused and secure authenticator app for managing two-factor verification codes across email, developer tools, cloud services, finance systems, and other important accounts.
It supports both TOTP and HOTP authenticators. Codes refresh automatically when needed, and you can tap a code to copy it quickly. Add authenticators by scanning a QR code, importing from the clipboard, or entering a secret manually. When moving to a new device, export your authenticators as a QR code for a smoother transfer.
Key features:
- Manage TOTP and HOTP verification codes
- Add codes by QR scan, clipboard import, or manual entry
- Search by service name or account
- Protect sensitive codes with device authentication and app lock
- Transfer authenticators by QR code
- Support for dark mode, light mode, and multiple languages
Link Auth keeps two-factor verification clear, organized, and ready for everyday use.
