Our verdict on OTPeer Authenticator
OTPeer Authenticator is a free, open-source two-factor authentication app for macOS, Windows, Linux, and the terminal. It generates both TOTP and HOTP codes, stores accounts in an encrypted local vault, and supports account migration from Google Authenticator, Microsoft Authenticator, Facebook Authenticator, Aegis, 2FAS, and andOTP. It suits desktop users who want local control of authenticator data and a terminal-access option through its Node.js CLI.
Its standout feature is peer-to-peer vault synchronization over a local network. QR-code device pairing connects devices directly, while encrypted account export and restore provide a separate migration path. This combination is useful for users who want several desktop devices to share authenticator accounts without relying on a hosted synchronization service. The import coverage also makes it more practical for moving from several established authenticator apps and backup formats.
The platform fit is deliberately desktop-oriented: builds are available for macOS, Windows, and Linux, with terminal access through the CLI. Mobile apps are planned, so OTPeer Authenticator is a stronger match for a desktop-centered workflow than for users who need phone-based access today. Choose it for free, open-source authentication with encrypted local storage, local-network synchronization, and broad migration support; choose another option if mobile apps are central to your authentication routine.
