❗ ❗ ❗ (To find out about WinAuth, read the original repository's README) Unfortunately, original WinAuth development has been archived, without leaving a way to contact author & suggest updates. I've forked it (on top of Florastamine 2020-09-01 update) and added some essential features:

• Winauth is now standalone .exe file (produced by Costura.Fody).[to make it fully portable, copy WinAuth.xml from %appdata%\WinAuth aside to WinAuth.exe]
• Search-box to quickly filter the desired sites from list.
• Option to drag & drop QR-image onto the Add-Authenticator window.
• Option to auto-copy the one-time code if the searched result is single.
• Option to auto-close app (to save an extra click) when you copy the code..
• Fixed "Auto-Update" interval option being erased on next re-open.

(One issue still persists which we couldn't fix - when having tons of sites, WinAuth takes a while to open on startup).

• To Build , install NuGet packages at first, and then Build (if any issues, clean solution and restart VS).
