OTPeer Authenticator
What OTPeer Authenticator is
OTPeer Authenticator is a free, open-source application for generating TOTP and HOTP two-factor authentication codes on desktop computers and in a terminal. It runs on macOS, Windows, Linux, and terminal environments. Devices pair with a QR code or short pairing code, then merge encrypted vaults over the local network without a relay or backend server. Vault data stays on users’ devices, and setting a password protects the vault with AES. The product says it has no cloud, account, or telemetry and does not upload secrets. Imports include Google, Microsoft, and Facebook authenticator exports, plus backups from Aegis, 2FAS, and andOTP. Each synced device stores a complete vault copy. Desktop downloads include macOS Apple Silicon and Intel installers, Windows, and Linux AppImage or .deb packages. The CLI is distributed through npm as authenticator-clui. iOS and Android apps are described as coming soon.
