TotpCat — Secure TOTP Authenticator for macOS

TotpCat is a lightweight, privacy-first TOTP authenticator built natively for macOS.

It lives quietly in your menu bar — always ready to show your 2FA codes when you need them.

No accounts, no cloud sync, no tracking. Just your secrets, safely stored in your Keychain.

Why TotpCat?

Because most authenticators are either bloated or web-based.

TotpCat focuses on simplicity, speed, and trust — everything happens locally.

It’s perfect for developers, privacy-conscious users, and anyone who prefers native macOS UX.
