Jessecar96 (GitHub) — original author / community‑maintained third‑party

Jessecar96 is an individual GitHub developer known as the original author of the open‑source project Steam Desktop Authenticator (SDA). SDA is a community tool that emulates the Steam Mobile Authenticator to provide Steam Guard codes and manage mobile authenticator data on desktop machines. The project was published and maintained on GitHub and attracted community interest because it allowed users to manage Steam two‑factor authentication (2FA) outside the official Steam mobile app.

The project is not a commercial company — it began as a hobby/open‑source effort by a GitHub user and has been carried forward by community contributors and forks. There is no official corporate website; support and development take place in the GitHub repository, issue tracker, and community forks. Because the code touches account security, many community forks and maintainers periodically update it to keep compatibility with Steam APIs and to address security/maintenance concerns.
