Mac + Token + I/O
Your smartphone authenticator app, now on your Mac.
A security-first TOTP/HOTP authenticator built natively for macOS. Your secrets are AES-256 encrypted, hardware-bound, and never leave your device. No cloud. No sync. No account. Just your codes.
Most people transfer authenticator accounts to their Mac by screenshotting the export QR code and sending it via email, Telegram, or WhatsApp. That screenshot — containing all your secret keys — now lives in chat histories, email servers, and cloud photo backups.
Mactokio solves this. Point your Mac's webcam at the QR code on your phone screen. Your secrets travel through the air, not through the internet. No screenshot. No file transfer. No cloud.
The recommended way to import your accounts:
- On your phone, open your authenticator app → export/transfer accounts
- In Mactokio, click + → From Camera
- Hold your phone's screen up to your Mac's webcam
- Done — all accounts imported and encrypted
The camera uses confidence-based detection across multiple frames, with visual feedback (tracking → green for success, red for invalid QR). Your secrets are encrypted the instant they're read.
Also supports:
- From File — QR code image or text file
- From Clipboard — QR screenshot or
otpauth://URI
Supports standard otpauth:// URIs and Google Authenticator migration format (otpauth-migration://).
