How to change the password on 500px web publishing

I recently changed my password on my 500px account but I don't see a way to change it on the fastpictureviewer web publishing plugin. Any ideas?

As silly as it sounds, there is no mechanism to reset the access credentials stored in FPV Pro at this time (we must think of something, like a "Reset credentials" button on the plug-in's About page).

In the meantime, here is a (little barbarian) fix: using regedit.exe, navigate to

HKEY_CURRENT_USER\Software\ARSD\FastPictureViewer\Publishing\Plugins\{23B2FD19-6B49-489D-B186-F821E1A94241}

You will find all the 500px plugin's parameters in there, notably a value named 'PrivateStream' which contains your authorization credentials, strongly encrypted.

Just erase this value (right-click its name and click Delete) and the plug-in will ask for a new authorization the next time you use it.

As a side note, your password is *not* stored there. In fact, FastPictureViewer never had your 500px password as the authorization is made on the 500px site itself: what we store is the authorization token created by 500px and which can be revoked from the 500px.com website just like you'd un-authorize any other app.

Thanks for the input but now when I try to authorize it, it gives me this error:
Could not connect to the 500px authorization server. The error code was 0x80004005. Unspecified error. I also tried updating to the latest version of fastpicture viewer with the same result.

Yes, we know that. We wrote to 500px about this, as we get a "server error" back from them, but no satisfactory answer so far (after about a week)

I got some news: apparently 500px forgot about FastPictureViewer! More concretely, the app registration on their site is no longer there for some reason, and since apps authenticate themselves with a special { key + secret } pair, which was no longer on the 500px servers, it was impossible to authenticate new FPV copies (but already authenticated instances kept working and it was still possible to upload images).

A tech is looking into this as I write this, hopefully they will be able to restore or recreate the registration on their side and your installed FPV Pro copy will start working again auto-magically, i.e. you'll be able to authorize the program and upload your pics. At worse the 500px plug-in will need a new pair of keys and you'll need to download FPV Pro again to fix the problem.

More on this later...

Everything is back to normal, you should be able to authorize FastPictureViewer on 500px again now, no need to reinstall or update anything.
