Official domains
Use the exact addresses on this page to find our four official download sources. A similar name or high search ranking is not proof of origin. The MIT licence allows others to redistribute or modify the source; that does not make independently built or modified copies ours.
Publisher websites and official download sources#
| Address | What it is | Downloads? |
|---|---|---|
| opendesktopauthenticator.com | This site. Documentation and links only — it has never hosted an installer and never will. | No |
| github.com/opendesktopauthenticator/open-desktop-authenticator | The project repository: source, public build workflow and releases. Use its Releases page for direct downloads. | Yes |
| apps.microsoft.com — Open Desktop Authenticator | The Microsoft Store listing for product ID 9NMM2XJ6HZ1D, published by MASTERPANEL LLC. Microsoft signs the Store AppX package. | Yes |
| open-desktop-authenticator.en.softonic.com | Softonic’s authorized Windows x64 listing, naming MASTERPANEL LLC. Its “Trusted Program” and “Official distributor” labels were checked on 1 October 2026. A tested route returned a separate downloader; read the notice below. | Yes |
| open-desktop-authenticator.en.uptodown.com/windows | Uptodown’s Windows x64 listing, naming MASTERPANEL LLC as developer. Version 1.5.1 and its displayed checksum were checked against the GitHub release on 15 October 2026. | Yes |
| masterspanel.com | The company that publishes this. Names the product and links back here, which is the other half of the check. | No |
Our four official download sources are Microsoft Store, GitHub, Softonic and Uptodown. The download page explains which to take, and how to check what you got.
What Softonic's labels mean#
The ODA listing on Softonic names MASTERPANEL LLC as developer. Softonic's “Official distributor” label means it has authorization to offer ODA. Its “Trusted Program” label reports a clean VirusTotal scan of the listed file. We checked both labels on 1 October 2026. They are distribution and file-scan information, not an independent security audit of ODA.
A public Softonic download tested on 1 October 2026 returned a separate Softonic downloader instead of the original ODA installer. Resolution is not verified; use Microsoft Store, GitHub or Uptodown. Read the download notice. For an ODA installer obtained there, check the publisher signature and compare the file with the matching GitHub release checksum. ARM64, portable Windows and Linux packages are available on GitHub.
What this page is for#
The attack this project exists to answer is a search result that looks official. A counterfeit Steam Desktop Authenticator can display working codes while copying account secrets. Similar names and search rankings are not proof of origin — what a counterfeit build actually does covers the pattern.
A list like this only helps if it is the same list everywhere, which is why the release process compares the GitHub organisation name against this page rather than against somebody’s memory. If this page, the repository and a download disagree, stop and investigate. Do not choose whichever source looks most reassuring. Follow the signature and provenance checks; a website can be compromised too.
If you find something claiming to be us#
Report it through the reporting form — suspected clone sites are one of the things it is for, and a report costs you a minute and may save somebody their inventory. Do not send us vulnerability details there; the security page has the private channels for that.
GitHub, Microsoft, Softonic and Uptodown can serve files through their own delivery domains after you follow the links above. A delivery redirect alone is not proof of a fake; a lookalike page offering its own build needs independent verification. If you ran an untrusted authenticator and gave it Steam credentials or maFiles, treat those secrets as potentially compromised and work through the compromised-account steps rather than hoping. Open Desktop Authenticator cannot undo that, and neither can we.
