Is WinAuth for steam any good? And is it Vac safe?

Thanks. One of my favorite shows.

I heard that there was a glitch where you couldn't confirm market confirmations. Has this been patched?

Winauth:
"Security and Encryption
All private authenticator data is encrypted with your own personal password, salted and enhanced with key strengthening to reduce the ability for brute force attacks. The data can also be protected using Windows in-built Data Protection API, which will “lock” the data to a single computer or account, making it completely unusable if copied to another computer.

A YubiKey can be used to further enchance the protection by providing a secret key stored only on the YubiKey itself, and must be physically plugged into the computer before WinAuth can be opened.

Each authenticator can also additionally have its own secondary password that is required before any codes are decrypted, calculated and displayed.

Finally, all codes are drawn directly onto the screen to prevent any malware from “windows spying”."

WinAuth is the best implementation of Steam 2FA from all I evaluated as "good" when implementing ASF 2FA.

In fact, ASF 2FA was initially based on SDA code, then I rewrote it entirely and now it's based on stripped-down WinAuth code, with my own ASF improvements.

Normally I'd say that ASF 2FA in its current form is the best, but it's not user friendly by definiton and not meant to be used as one, so I can say - definitely consider using WinAuth over SDA - SDA is really crappy, crappy to the point that I spent time rewriting working code into another one, and that takes enough time to think twice if it's worth doing in the first place.

Yes, no need to repost the same thread when my question is identical to this one.
