Our verdict on Authman

Authman is a free, open-source authenticator for individuals managing time-based one-time password accounts across devices. It supports iOS, Android, Windows and Mac, making it suitable for people who want one token collection available on both mobile and desktop. Accounts can be added by entering a secret or scanning a QR code, and generated codes can be copied when needed. The product is designed for personal 2FA token management rather than centralized identity or SSO administration.

Its strongest practical advantage is the combination of cross-platform access and encrypted synchronization. Authman accounts connect tokens between supported devices, while biometric unlocking with Touch ID or Face ID adds a direct access option on compatible hardware. Import and export support can help with token migration, and backup QR-code display provides another way to preserve account setup. Custom icons and images add organization without changing the app’s TOTP-centered scope.

Authman is a focused choice for users who want a free authenticator with open-source availability, QR-based setup and synchronized access across mobile and desktop. The trade-off is its narrow purpose: organizations seeking identity administration, SSO controls or a broader authentication platform should look elsewhere. Synchronization also depends on an Authman account, so users choosing the app should be comfortable with that account-based model. For straightforward TOTP management across the listed platforms, Authman offers a concise feature set without a paid tier.
