Winticator
What Winticator is
Winticator is a free, open-source desktop authenticator for Windows, macOS, and Linux. It generates time-based one-time passwords according to RFC 6238 and operates entirely offline, making no network communications. You can scan TOTP QR codes shown on your screen, including Google Authenticator migration codes that use the otpauth-migration:// scheme. Entries can be exported and imported through a proprietary password-protected backup file, or displayed as QR codes for transfer to another device. Selecting an entry copies its current code to the clipboard, which clears automatically when that code expires. Winticator is presented as an independent technical demonstration and reference implementation, not a commercial product. The MIT License permits commercial use under its terms. Current downloads include Windows x64, macOS Apple Silicon, and Linux x64 binaries; macOS Intel binaries are no longer published. Large migration QR codes may be difficult to decode.
Who it suits
Winticator suits desktop users who need offline TOTP codes on Windows, macOS, or Linux. It also fits people moving entries from Google Authenticator or transferring them between devices.
What it does well
- Works entirely offline with no network communication
- Supports Windows, macOS, and Linux binaries
- Imports Google Authenticator migration QR codes
- Password-protected backup export and import
- Clipboard clears codes after expiration
What to know first
- No macOS Intel binary in latest releases
- Advanced enterprise features are out of scope
- Provided without warranty or official support
- Dense migration QR codes may fail to scan
Verdict
Winticator provides offline desktop TOTP generation with migration, backup, and transfer options. Its reference-implementation focus and missing macOS Intel release matter for production or older-Mac users.
