What Authenticator Pro does
Authenticator Pro generates time-based one-time passwords (TOTP) every 30 seconds from secrets you add, either manually or by scanning a QR code. It can autofill the current code into a login form or let you copy it to the clipboard, and it supports Chrome sync so your tokens follow you across signed-in devices.
Authenticator Pro free vs paid
Authenticator Pro is free to install from the Chrome Web Store, with no separate paid tier listed. It's offered by an independent developer rather than a company, and its feature set (token management, themes, password protection) is included at no cost.
Is Authenticator Pro safe?
The developer discloses that it does not collect or use your data, and the extension is not identified as a trader in the EU sense, meaning it's an independent project. Because it stores 2FA secrets, treat any authenticator extension with the same caution you'd give a password manager.
