OpenAuthenticator
What OpenAuthenticator is
OpenAuthenticator is a free, open-source desktop authenticator for Linux, macOS, and Windows. It uses time-based one-time passwords, or TOTP, and lets users add or delete authenticator tokens. Codes can be copied to the clipboard, and keys refresh automatically. The application fetches a favicon for each service to help identify tokens. The project credits otplib for cryptographic token generation and lists an MIT license. The repository documents local development: clone the project, install dependencies with npm, and run npm start. The README says npm run package creates a package for the local platform. The GitHub repository has a Releases section with no release entries and a Packages section with no package entries. The project is described as simple enough for broad everyday use, while its cross-platform design covers the three listed desktop systems. With no published releases or packages, the repository provides the route for obtaining the code, running it locally, and creating a local package.
Who it suits
It suits desktop users who need a free TOTP authenticator on Linux, macOS, or Windows. Developers can also use the documented npm workflow to run and package it locally.
